CONTRAINDICATIONS
MAINTENANCE
The device is contraindicated for use in:
1.0 CALIBRATION
• • •
•
•
Every time the GYNECARE THERMACHOICE UBT System is powered up, the controller checks the calibration of the temperature circuitry. The pressure measurement in the system is accomplished by utilizing two transducers. These transducers are internally calibrated and are temperature compensated which are accurate and stable over the operating range. They are also factory calibrated at installation. These pressure readings are checked against each other at power up and throughout the procedure. These sensors are of differential type, and therefore measure the balloon pressure relative to the outside atmosphere. In addition to the internal means of calibration, it is possible to ensure the proper operation of the system against other calibrated devices. The procedure is recommended to be performed on an annual basis. The procedure also needs to be carried out if it is believed that the system is behaving unexpectedly.
A patient who is pregnant or who wants to become pregnant in the future. A patient with a history of latex allergy or who has demonstrated a sensitivity to latex material (for catheter version 1.2 only). A patient with known or suspected endometrial carcinoma (uterine cancer) or pre-malignant change of the endometrium such as unresolved adenomatous hyperplasia. A patient with any anatomic or pathologic condition in which weakness of the myometrium could exist, such as history of previous classical cesarean sections or transmural myomectomy. A patient with active genital or urinary tract infection at the time of procedure (e.g., cervicitis, vaginitis, endometritis, salpingitis, or cystitis). A patient with an intrauterine device (IUD) currently in place,
Note: There are no calibration adjustments on the controller. If the unit does not meet the calibration requirements, it needs to be sent back to the manufacturer.
WARNINGS Failure to follow all instructions or to heed any warnings or precautions could result in serious patient injury. • The device is intended for use only in women who do not desire to bear children because the likelihood of pregnancy is significantly decreased following this procedure. There have been reports of women becoming pregnant following this procedure. Pregnancies after ablation can be dangerous for both mother and fetus. • Endometrial ablation using the GYNECARE THERMACHOICE UBT System is not a sterilization procedure. • Patients who undergo endometrial ablation procedures who have previously undergone tuballigation are at increased risk of developing post ablation tubal sterilization syndrome which can require hysterectomy. This can occur as late as 10 years post-procedure. • Endometrial ablation procedures using the GYNECARE THERMACHOICE UBT System should be performed only by medical professionals who have experience in performing procedures within the uterine cavity, such as IUD insertion or dilation and curettage (D&C), and who have adequate training and familiarity with the GYNECARE THERMACHOICE UBT System. • Endometrial ablation procedures do not eliminate the potential for endometrial hyperplasia, or adenocarcinoma of the endometrium and may mask the physician'S ability to detect or make a diagnosis of such pathology. • The GYN ECARE THERMACHOICE III UBT Balloon Catheter is for single use only do not reuse or resterilize. • Do not treat patients for more than one therapy cycle in a given treatment session because of the potential for transmural injury to the uterus or injury to adjacent viscera. • UTERINE PERFORATION • Uterine perforation can occur during any procedure in which the uterus is instrumented. Use caution not to perforate the uterine wall when sounding the uterus, dilating the cervix or inserting the catheter. • Any of the following indicates possible uterine perforation.

1. If the catheter can be inserted to a greater depth than was determined by the uterine sound 2. If the pressure cannot be stabilized at 160 - 180 mmHg with up to 35 ml* of fluid 3. If the pressure drops quickly at any point during the procedure *35 ml of fluid in the THERMJ1CHOICE III device is approximately equal to the 30 ml used
in the THERMACHOICE I clinical study. • If a perforation is suspected, THE PROCEDURE SHOULD BE TERIvllNATED IMMEDIATELY. The physician may elect to perform a diagnostic procedure to confirm perforation. If the physician cannot absolutely rule out perforation, the procedure should be abandoned. • For patients in whom the procedure was aborted due to a suspected uterine wall perforation, a work-up for perforation should be considered prior to discharge. • If a perforation is present, and the procedure is not terminated, thermal injury to adjacent tissue may occur if the heater is activated. • After completing the procedure it is important not to touch the GYNECARE THERMACHOTCE Uterine Balloon for the following reasons: - The balloon is covered with blood and body fluids - There are mechanical and electrical parts that could puncture the balloon • Proper care should be taken in disposing of the catheter.
PRECAUTIONS • The GYNECARE THERMACHOlCE III UBT catheter, controller, and umbilical cable are designed as a system. To ensure proper function, never use other components with the GYNECARE THEIDvlACHOICE L13T System. • A starting pressure of 160 - 180 mmHg is recommended and typically requires 6 - 15 ml of fluid and may require as much as 35 ml for the THERMACHOlCE TIT catheter and 30 ml for the THERMACHOICE I catheter. Titration to achieve a stable pressure (no fluctuations greater that ±10 mmHg for at least 30 seconds) prior to activating the heating element is critical to proper functioning of the device. When inserting fluid, do not exceed a pressure of 200 mmHg. Typically, pressure levels decline slowly during the course of the procedure as the uterus relaxes. If a pressure of 160 - 180 mrnHg cannot be reached with up to 35 ml or less of fluid for the THERMACHOICE HI catheter and 30 ml for the THER.c,1ACHOICE I catheter, or if there is a rapid drop in pressure, it is likely there is a uterine perforation. • Rapid loss of pressure during a therapy cycle may indicate a uterine wall defect. Adding additional fluid to the balloon may create (or exacerbate if already present) a uterine wall defect such as a perforation. • Those patients who have undergone endometrial ablation and are later placed on hormone replacement therapy should have progestin included in their regimen in order to avoid the increased risk of endometrial adenocarcinoma associated with unopposed estrogen replacement therapy. • Never add additional fluid during a therapy cycle. • The safety and effectiveness of the GYNECARE THERMACHOICE UBT System has not been fully evaluated in patients: - with large uterine cavities (>35 ml* in volume or uterine sound>12 cm)
GYNECARE THERMACHOICE UBT System Operating Manual
Page 7
- with small uterine cavities «2 ml in volume or uterine sound <4 cm) - with submucosal myomas, bicornuate or septate uteri or previous endometrial resection/ ablation - undergoing repeat endometrial ablation procedures - who are post-menopausal *35 ml of fluid in the THERMACHOICE III device is approximately equal to the 30 1111
used in theTHERMACHOICE I clinical study. • It has been reported that patients with a severe anteverted retroflexed or laterally displaced uterus are at an increased risk of uterine wall perforation during any intrauterine manipulation. The clinician should use discretion in patient selection. • A false passage can occur during any procedure in which the uterus is instrumented, especially in cases of severe anteverted retroflexed or a laterally displaced uterus.

ADVERSE EVENTS CLINICAL STUDY In a study of 134 women performed with a previous generation balloon catheter (version 1.2) [without the fluid circulation mechanism inside the balloon]' the most frequent events that have been reported following completion of the procedure include:
•
•
•
• •
•
Cramping/pelvic pain - Post-treatment cramping was reported in 91.8% of the patients which ranged from mild to severe as reported during the intra-operative and immediate post-operative period. This cramping will typically last a few hours and rarely continues beyond the first day following ablation. The use of non-steroidal anti-inflammatory drugs (NSAIDs) prior to and following UBT is usually sufficient to manage cramping and pelvic pain. Nausea and Vomiting - Nausea and vomiting were reported for 23.9% of the patients in the immediate hours following the procedure. This may be attributed to general anesthesia, and can be easily managed with medication. Endometritis was reported in 2.1 % of patients. All patients responded to a course of oral antibiotics. Post-procedure symptoms such as pain, fever, nausea, vomiting, difficulty with defecation or micturition were reported. Failure of such symptoms to resolve over a reasonable period of time warrants evaluation by appropriate medical personnel. Pregnancy was reported in one patient (0.8%) resulting in a 2-month premature live infant. Pregnancy following endometrial ablation is dangerous to both mother and fetus. Hematometra was reported in 0.6% of patients treated in clinical studies conducted outside of the United States. In all patients, the hematometra was resolved with insertion of a uterine sound. A single perforation of the uterus was reported in a controlled clinical study.
OTHER ADVERSE EFFECTS As with all endometrial ablation procedures, serious injury or death can occur. The following adverse effects might be potentially expected or have been reported in association with the use of the GYNECARE THERMACHOICE UBT System:
Recommended Separation Distance d = [1.17J ,;p
d = [1.17J /p
80 MHz to 800 MHz
d = [2.33] ,;p
800 MHz to 2.5 GHz
'where P is the maximum output power rating of the transmitter in watts (W) according to the transmitter manufacturer and d is the recOlnmended separation distance in metres (m). Field strengths from fixed RP transmitters, as determined by an electromagnetic site survey,' should be less than the compliance level in eilch frequency range.' Interference may occur in the vicinity of equipment marked "~th the follO,,~ng symbol:
((<e))) I
NOTE 1: At 80 MHz and 800 MHz, the higher frequency range applies. NOTE 2: These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from structures, objects and people. Field strengths from fixed transmitters, such as base stations for radio (cellular I cordless) telephones and land mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted theore tically with accuracy. Tb assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey should be considered. If the measured field strength in the location in which the GYNECARE THERMACHOICE UBT system is used exceeds the applicable RF compliance level above, the GYlTECARE THERMACHOICE UBT system should be observed to verify normal operiltion. If abnorn1a1 performance is observed, additional measures may be necessary, such as reorienting or re10cating the GYNECARE THERMACHOICE UBT system. " Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 Vim.

6. Infection or Sepsis 7. Perforation 8. Post-ablation-tubal sterilization syndrome - This is a complication following endometrial ablation in women who have also previously undergone tuballigation. The pathophysiology of this condition is believed to be related to the regeneration of endometrium in the cornual areas of the uterus. Blood from these glands can flow back into the proximal fallopian tubes in cases where the lower uterine segment is extensively scarred. The proximal oviduct becomes filled with blood and fluid causing symptoms similar to those of an ectopic pregnancy. 9. Complications leading to serious injury or death.
CLINICAL TRIAL The CYNECARE THERMACHOICE mc catheter (version 3.0) and CYNECAIZE THERMACHOICE nc catheter (version 2.0) includes an active mechanism for circulation of the DsW within the balloon. The CYNECARE THERMACHOICE catheter (version 1.2) has a passive circulation which is based on convection. The clinical data presented below were obtained using the previous generation non circulating balloon catheter, however, laboratory testing (ex-vivo experiments conducted on extirpated human uteri) has shown that the active circulation of fluid within the balloon will lead to a more even distribution of heat at the balloon surface, and thereby over the endometrial tissue. Conclusions: In a study performed with a previous generation balloon catheter (version 1.2) [without the fluid circulation mechanism inside the balloon] at twelve, twenty-four, and thirty-six months of follow-up, balloon ablation was demonstrated to be at least as safe (with fewer intra-operative complications and shorter procedure times), and as effective as hysteroscopic rollerball ablation in reducing menstrual bleeding to a clinically acceptable level in menorrhagic women who had completed their childbearing. Furthermore, statistically equivalent and significant reductions in patient-reported dysmenorrhea (mild, moderate, severe menstrual cramps), PMS symptoms (mild, moderate, severe common PMS symptoms), and overall impact of menses on lifestyle (scale of 1-10; l=none, lO=severe) were experienced by both groups. Purpose: The use of balloon thermal ablation for the treatment of menorrhagia for benign causes in an anatomically normal uterine cavity was compared with rollerball electrosurgical endometrial ablation with regard to safety and effectiveness. The primary effectiveness measure was a validated dimy scoring system (adapted from Higham JM, O'Brien PMS, Shaw RW, Assessment of menstrual blood loss using a pictorial chart, Br J Obstet GynaecoI1990;97:734-9l. Success was defined as the reduction of excessive menstrual bleeding to normal flow or less. Secondary endpoints evaluated were overall percent decrease in diary scores and responses from a quality of-life questionnaire. The endpoints for safety were based on the evaluation of adverse events associated with each procedure, including device-related complications, time of procedure, and type of anesthesia use.

Methods: This randomized, prospective, multicenter clinical investigation obtained using the previous generation non-circulating balloon catheter was conducted at 14 sites using investigators highly experienced with hysteroscopic rollerball endometrial ablation. All patients were >30 years old, premenopausal, and had completed childbearing. All had an anatomically normal uterine cavity >4 cm and <10 cm. Three months of documented menorrhagia for benign causes was a requirement for inclusion and was confirmed with a diary score of at least 150 points. Endometrial biopsy and pap smear were required to rule out (pre)malignant uterine disease. No uterine thinning medications could be used for three months prior to treatment, and all patients underwent a three-minute suction curettage just prior to treatment. Selection of anesthesia regimen was left to the individual investigators. Treatment success was defined as reduction in menses to a diary score less than or equal to 75 in order to assure a return to eumenorrhea. In the original Higham study, a diary score of 100 had an 86% sensitivity and an 81 % specificity for true menorrhagia for benign causes as determined by chemical analysis of the saturated pads.

Menorrhagia can be caused by a variety of underlying problems including but not limited to, endometrial cancer, myomas, polyps, anovulation, drugs, and dysfunctional uterine bleeding. Patients should always be evaluated to determine the cause of their excessive uterine bleeding before any treatment option is initiated.
When parameters extend outside the normal operating range, the controller sounds an audible alarm (intended only as a warning signal to the clinician). These values are listed below and reside between normal operating parameters (see previous chart):
Consult medical literature relative to various endometrial ablation techniques, indications, contraindications, complications, and hazards prior to the performance of any endometrial ablation procedures.

ERROR MESSAGES Under electrostatic discharge to the controller or abnormal line voltage conditions, i.e., surge and fast transients, the system may reset to the initial power-up state. It is also possible that the unit may tenninate the procedure with an error code. In this case, turn off the power to the controller and restart the procedure. In addition to the operating messages listed in the "Directions," the message Display also provides messages which indicate conditions under which the controller either will not begin treatment or will terminate treatment after the heating cycle has been initiated.
PATIENT COUNSELING As with any procedure the physician needs to discuss risks, benefits and alternatives with the patient prior to performing endometrial ablation. In addition, the physician should discuss signs and symptoms of potential complications such as bleeding, infection or thermal injury. Page 14
GYNECARE THERMACHOICE UBT System Operating Manual
Page 23
Note: Never add additional fluid during a therapy cycle as this could create (or excerbate if already present) a uterine wall defect such as a perforation. 4.4 When the treatment cycle is completed, the Message Display will alternate
between the following messages: THERAPY COMPLETED
and
COOLING DOWN PLEASE WAIT
4.5 The controller automatically terminates the heater at the end of the treatment (cycle) and an audible alarm will sound.
The device is intended for use only in women who do not desire to bear children because the likelihood of pregnancy is significantly decreased following this procedure. Post-procedure pregnancy may be dangerous for both mother and fetus. Patients of childbearing capacity should be counseled that endometrial ablation is not a sterilization procedure and should be provided an appropriate birth control method. Patients with childbearing capacity should be cautioned of the potential complications which may ensue if they should become pregnant. Vaginal discharge is typically experienced during the first few days following ablation and may last as long as a few weeks. Generally, the discharge is described as bloody during the first few days; serosanguinous by approximately one week; then profuse and watery thereafter.
5.0 POST-TREATMENT
PRETREATMENT PREPARATION OF PATIENT
5.1 The cool down cycle takes 30 seconds. When the cycle is completed, the Message Display will read the fC!lloWing:
The lining of the uterus should be thinned prior to GYNECARE THERMACHOICE UBT. This can be accomplished by timing the menstrual cycle to the early proliferative phase, administering pretreatment drugs such as danocrine or GnRH agonists, or performing suction or sharp curettage immediately prior to performing the endometrial ablation. The optimum pretreatment regimes have not been determined at this time.
THERAPY & COOL DOWN COMPLETED
then
REMOVE FLUID REMOVE CATHETER
Remove fluid by drawing back on syringe while depressing trumpet valve. Remove all fluid from balloon. Remove the balloon catheter. Check that the entire fluid volume is withdrawn.
It is recommended that a non-steroidal anti-inflammatory drug (NSAID) be given at least one hour prior to treatment and continued post-operatively as necessary to reduce intra-operative and post-operative uterine cramping.
5.2 Disconnect the catheter pressure line from the controller.
5.3 Disconnect the circulation catheter plug, if applicable, from the controller.
DIRECTIONS FOR USE
5.4 Disconnect the umbilical cable from the catheter (for version 1.2) or from the catheter umbilical cable connection (for versions 3.0 and 2.0) by pulling back the gray collar.
Please read all directions, precautions and warnings prior to use.
5.5 Disconnect the umbilical cable from the controller by holding the stainless steel ribbed shell and pulling back. Do not pull on the cable itself. 5.6 Discard the catheter. Retain the umbilical cable and disinfect for the next case. 5.7 Power must be turned off before beginning another procedure. Note: When a controller is left on without use for 8 hours, the controller freezes and displays the following message: MAX TIME EXPIRED TeRN POWER OFF
OPERATING PARAMETERS / ALARM AND DISPLAY MESSAGES
1.0 SET-UP
1.1 The following items are required for use of the GYNECARE THERMACHOICE UBT System. GYNECARE THERMACHOICE UBT System • 1 sterile disposable balloon catheter (see catheter version matrix below) and syringe (30 mll • 1 umbilical cable • 1 controller • 1 power cord Catheter Version 3.0
Circul~tion catheter

The controller is designed to monitor time, temperature and pressure within parameters present at the factory. • •
ALERT. If the temperature and / or pressure increases or falls beyond a level preset at the factory, the controller will sound a short audible alarm. HAZARD ALARM/TERMINATION OF PROCEDURE (HEATER SHUT OFF LIMITS). If the temperature and/or pressure increase or falls outside the operating parameters, the controller will sound an alarm, terminate the procedure and display an error message. Additionally, if the controller detects a system

Medical Supplies • 50 ml sterile injectable plain 5% dextrose in water (DsW) • tenaculum (weighted) speculum • uterine sound, cervical dilator(s) • sterile drape for umbilical cord (optional) Note: Use only plain DsW to inflate balloon catheter - never use any other fluid. 1.2 Open the sterile package containing the GYNECARE THERMACHOICE UBT Catheter and Syringe. Disinfect umbilical cable as described at the end of this manual. Handle balloon portion of the catheter carefully to prevent damage. 1.3 Make sure that the controller power is off before making the connection (Steps 1.4 - 1.6). 1.4 Plug the power cord into the back of the controller and into the wall outlet. 1.5 The umbilical cable includes a connector plug at each end to connect the balloon catheter to the controller. Visually inspect the cable and connector plugs to ensure there are no defects or signs of wear. Drape umbilical cable with sterile drape, if necessary, and attach cable to the connector on the catheter umbilical cable connection (for catheters version 3.0 and 2.0) or at the end of the balloon catheter for version 1.2 (match arrows on umbilical cable to notch on catheter). Attach the opposite end of the cable to the connection port on the front panel of controller. (Align red dots from umbilical cable to controller). (See Diagram 4 for circulation catheter versions 3.0 and 2.0 and Diagram 5 for non-circulation catheter version 1.2).
4.0 TREATMENT 4.1 Message Display (alternating):
READY PRESS START
and STABILIZE START PRESSURE>150 When a steady pressure of 160-180 mmHg is maintained, press START (<i» button on controller to activate the heater. Do not add fluid once heater is activated, as this could create (or exacerbate if already present) a uterine wall defect such as perforation. Hold the balloon catheter immobile and centered in the uterine cavity during procedure (with the valve oriented upwards). Failure to hold the balloon catheter immobile during procedure can result in catheter failure. Note: Ensure that the balloon catheter is centered in the uterus to minimize potential overheat error codes during the treatment process. Prior to activating heater. ensure that fluid is on all sides of catheter tip. It is no longer necessary to maintain contact with the fundus. 4.2 After the start button is pressed, the controller activates the heater to achieve treatment temperature of 87°C (188°P) within 4 minutes. (This preheat cycle may take up to 4 minutes for larger uteri, but is usually 15-45 seconds). PREHEATING TO 87°C Note: If the treatment temperature of 87°Cis not reached within 4 minutes, the controller will terminate the procedure. Remove the fluid, remove the catheter. Note: During treatment and in case of emergency, the STOP ( @ ) button can be pressed to terminate the procedure. The stop button will power down the heater and the heater function can only be resumed by turning the unit off and restarting. 4.3 Message Display:
THERAPY CYCLE 87°C, 8 MIN
Once 87°C is reached, an audible tone ,vill indicate the automatic activation of the 8 minute therapy cycle. The Time elapsed will be shown on the "THERAPY TIME" display. After the preheat cycle is completed the time resets to 0:00. The displayed time represents the exact therapy cycle time. Note: Pressure may rise slightly with initial heating. It is common to then see the pressure fall gradually during procedure. If the pressure reaches 200 mmHg, an alarm will sound. If the pressure exceeds 210 mmHg for more than 2 seconds, the controller will terminate the procedure. The procedure may be restarted with a lower starting pressure to complete an 8 minute therapy. Note: A rapid drop in pressure or a failure to maintain pressure may be the result of a catheter leak or uterine perforation. After sufficient cooling, remove the balloon catheter. A work-up for perforation should be considered prior to discharge.
