Device Description
DEVICE DESCRIPTION
The GreenLight XPS Laser System™ is designed for the ablation and coagulation of soft tissue using light. One example procedure is the endoscopic (transurethral) resection of the prostate for the treatment of Benign Prostatic Hyperplasia. The Laser System consists of a console, which generates the green laser light and a fiber optic delivery device that transmits laser light from the console to the patient. This Laser System is not intended to treat prostate cancer.
Console Description The console is a diode-pumped Solid State Laser utilizing Nd:YAG laser gain medium and Acousto-Optic Q Switch. Primary wavelength is 1064nm. Frequencydoubling crystal is used to generate 532nm output beam. Quasi-CW pulse repetition rate is 15KHz to 22 KHz depending on output power. Pulse duration is ~100ns. Pulse energy is ~8mJ at maximum power (180W). The console generates visible green 532nm laser light. In vaporization mode the power settings range from 20 W to a maximum power determined by the fiber delivery device. In coagulation mode the power settings range from 5 to 40W. The console features a “plug and play” capability that self adjusts to the facility’s individual voltage requirements, eliminating the need for electrical modifications of the operating facility. This Laser System also includes internal cooling mechanisms ensuring safe operating temperatures with no external water connection. Laser energy emission and system status changes are activated through a surgeoncontrolled, color-coded footswitch or system touch screen feature.
FiberLife The GreenLight XPS Laser System is equipped with the FiberLife feature. FiberLife continuously monitors the temperature of the tip of the fiber and momentarily stops the laser emission when the fiber gets too hot. In most cases, this will prevent damage to the fiber if tissue or vapor bubbles accumulate on the tip, or if for other reasons there is damage due to excessive heating of the fiber. In most cases the laser will turn back on immediately and the procedure continues without interruption. There will be noticeable “blinking” of the working beam. If the FiberLife feature is activated continuously, vaporization efficiency will be significantly reduced. In this case the fiber should be cleaned or replaced. The console will automatically detect this condition, put the laser in Standby mode and display an informative message.

Section 1:
Device Description
FiberLife will also stop laser emission if the laser is accidentally fired while inside the cystoscope. Generally, this will prevent serious damage to the cystoscope. However, some discoloration of the metal may still occur which could increase the possibility of corrosion.
Coagulation A feature new with GreenLight XPS is pulsed coagulation. In this mode, activated when the coag footswitch is pressed, laser emission is pulsed at a rate of ~12Hz with a duty cycle of ~25%. This mode improves the coagulative effect when compared to the continuous emissions typically used by other lasers.

Accessories Video Camera Filter A video camera filter must be inserted between the telescope and the camera (unless a comparable filter is built into the telescope). The filter comes in four versions, as shown in the table below. All versions have an optical density (OD) of 5 at a wavelength of 532 nm. This blocks most of the laser light, preventing saturation of the video camera sensor. The optimum transmission at wavelengths other than 532 nm and the filter diameter depends on the video camera and telescope model. The two most commonly used video camera filters, Models 10-0721 and 10-0722, are delivered with each Laser System. Model #

Laser Protective Eyewear Eyewear has been designed to protect operating room personnel from the 532 nm laser energy. The eyewear has a minimum optical density (OD) of 6.0 at 532 nm. The eyewear requirements for EU are 532 D L6. • Nearly clear Physician Laser Glasses. The essentially clear lens material
has very high visible light transmission and minimal color distortion.
• Orange Eye Protection Glasses. Although it has good visible light
transmission, the orange color of the plastic lens causes some color distortion.

obstructions; and vaporization of prostate tissue for men suffering from benign prostate hyperplasia/hypoplasia (BPH).
2.2
CONTRAINDICATIONS
The GreenLight XPS Laser System should only be used by a qualified and trained surgeon. The use of the Laser System is contraindicated for patients: • Whose general medical condition contraindicates surgical intervention • Where appropriate anesthesia is contraindicated by patient history • Where tissue (especially tumors) has calcified • For hemostatis of vessels over approximately two millimeters in • • • • •
diameter Where laser therapy is not considered the treatment of choice Uncontrolled bleeding disorders and coagulopathy Prostate cancer Acute urinary tract infection (UTI) Severe urethral stricture
The GreenLight XPS Laser System is contraindicated in the presence of severe urethral strictures; however, the system can be used in the treatment of urethral strictures with proper cautions. A severe stricture is any stricture with visible narrowing via urethrography or ultrasonography, with near total obstruction that makes passage of instruments difficult or dangerous. Care should be taken to avoid injury to urethral tissue.
2.3
POTENTIAL SURGICAL COMPLICATIONS AND RISKS
The same Potential Complications and Risks that exist for conventional or traditional surgery also exist for laser surgery. These include, but are not limited to, the following:
Non-Thermal Complications and Risks: Allergic reaction to medication Arrhythmia Aspiration Gas over-distension • Hypertension • Induced hemorrhage • Infection • Pain • Perforation • Pneumothorax • • • •

Physician Information
Thermal Complications and Risks: • • • • • • • • • • • • •
Chills Edema Fever Induced hemorrhage Delayed hemorrhage Leukocytosis Pain Perforation Ulceration Delayed healing Embolism Sepsis Stricture
Some of the Potential Surgical Complications and Risks have been further explained below: Bleeding: Patients may experience bleeding at the site of the laser therapy during or after laser therapy. Post-treatment hemoglobin and hematocrit are recommended to assess the severity of bleeding. Fever and Leukocytosis: Immediately after laser therapy, the patient may experience fever and leukocytosis, which are commonly associated with tissue destruction. These generally resolve without treatment. Cultures may be indicated to exclude the possibility of infection. Pain: Short-lived pain may occur immediately following endoscopic/cystoscopic laser therapy and may persist for as long as 48 hours. Perforation: Perforation can occur as a result of excessive exposure to laser radiation. Perforation can also occur from tumor erosion, or as a result of any endoscopic/cystoscopic procedure. To clinically diagnose perforations, patients must be closely monitored post-operatively through physical assessment of clinical symptoms, hematology studies as deemed appropriate, and radiography. Sepsis: Laser-ablated tissue may become infected after therapy. If a question of sepsis exists, a culture should be taken and other appropriate evaluations made.
