Sherlock 3CG* Tip Confirmation System

1 Overview 1.1 Indications for Use The Sherlock 3CG* Tip Confirmation System (TCS) is indicated for guidance and positioning of Peripherally Inserted Central Catheters (PICCs). The Sherlock 3CG* TCS provides real-time PICC tip location information by using passive magnet tracking and the patient's cardiac electrical activity (ECG). When relying on the patient’s ECG signal, the Sherlock 3CG* TCS is indicated for use as an alternative method to chest X-ray and fluoroscopy for PICC tip placement confirmation in adult patients. Limiting but not contraindicated situations for this technique are in patients where alterations of cardiac rhythm change the presentation of the P wave as in atrial fibrillation, atrial flutter, severe tachycardia, and pacemaker driven rhythm. In such patients, who are easily identifiable prior to PICC insertion, the use of an additional method is required to confirm PICC tip location.

1.2 Post Market Clinical Trial The Sherlock 3CG* Tip Confirmation System (TCS) is Bard’s next generation, fully integrated magnetic tracking and ECG-based peripherally inserted central catheter (PICC) tip confirmation technology, which represents the next evolution of the Sherlock* II Tip Location System and the previouslymarketed Sapiens Tip Confirmation System. The Sapiens TCS Post-Market Clinical trial was a prospective, single arm, single center study designed to assess the efficacy of the ECG method for correctly positioning the tip of catheters in adult patients. The primary endpoints were to assess the performance of the Sapiens technology with respect to: (1) the accuracy of the Sapiens technology with regard to correct positioning of the catheter tip when compared to postoperative chest x-ray, (2) safety of using an invasive intracardiac electrode, and (3) compatibility with peripherally inserted central catheters. One hundred fourteen (114) subjects received a PICC. Final PICC tip location was confirmed at the cavoatrial junction or within +/- 1 cm in 99.1% (113/114) of the subjects. No adverse events were reported.

1.3 Sherlock 3CG* TCS Description The Sherlock 3CG* TCS is designed to aid in PICC tip positioning through magnet tracking and ECG technology. It is designed to operate with Bard Access Systems’ catheter kits labeled [

] and “Sherlock 3CG* TPS Stylet”.

Note: When used in conjunction with catheter kits labeled [ through ECG technology.

] the device provides magnetic navigation information but does not allow positioning

ECG Positioning The Sherlock 3CG* TCS displays an ECG signal detected by the intravascular and body electrodes, which can be used for catheter tip positioning. In patients with a distinct P-wave, the P-wave will increase in amplitude as the catheter approaches the top of the cavo-atrial junction. As the catheter advances into the right atrium, the P-wave will decrease in amplitude and may be biphasic or invert.

Magnetic Navigation Permanent magnets are encapsulated within the tip of the Sherlock 3CG* TPS Stylet. No magnetic energy is generated by the Site~Rite Vision* Ultrasound System or the sensor. The Sherlock 3CG* TCS displays the relative position of the magnet-tipped stylet to the sensor. It does this in two steps: 1. Sherlock 3CG* TCS takes a background measurement of the ambient magnetic field during the calibration cycle. 2. Sherlock 3CG* TCS senses changes in the magnetic field. When the Sherlock 3CG* TCS detects the stylet, it displays the stylet tip location and orientation.

1.5 Warnings and Precautions This section specifies warnings and precautions specific to the functionality of the Sherlock 3CG* TCS. - See the Bard Access Systems' catheter Instructions for Use (IFU) for possible complications associated with peripherally inserted central catheter (PICC) placements and ECG positioning.

Warnings Warning: This product should only be operated by qualified medical personnel. Warning: Do not power the Sherlock 3CG* TCS in the presence of flammable anesthetic gases. Explosion may result. Warning: Do not attempt to sterilize the sensor. Damage to the equipment may occur. Warning: The following actions void the warranty of the Sherlock 3CG* TCS and may result in injury or equipment damage. - Opening or servicing the Site~Rite Vision* Ultrasound System with Sherlock 3CG* TCS by anyone other than Bard Access Systems’ authorized service personnel. - Removing system labels by anyone other than Bard Access Systems’ authorized service personnel. - Connecting the sensor or applied patient components to any unauthorized system or accessory. Refer to Section 1.4 for complete components. - Installation of unauthorized software. - Modification of system software settings without authorization by Bard Access Systems. Warning: If the Site~Rite Vision* Ultrasound System with Sherlock 3CG* TCS is visibly damaged, discontinue use immediately. Use of the damaged system may result in injury or equipment damage. Warning: Do not submerge the sensor in liquid or allow fluid to enter the connectors. Damage to the equipment may occur. Warning: Sherlock 3CG* TCS is not intended to diagnose or treat disease. Warning: Only Bard Access Systems’ authorized service personnel should attempt to service this equipment. Site~Rite Vision* Ultrasound System contains static sensitive components and circuits. Failure to observe proper static control procedures may result in damage to the system. Warning: Do not rely on ECG signal detection for catheter tip positioning when interpretation of the external or intravascular ECG P-wave is difficult. For example, when: - P-wave is not present - P-wave is not identifiable - P-wave is intermittent These conditions may be a result of heart rhythm abnormalities, atrial fibrillation, atrial flutter, severe tachycardia or presence of cardiac rhythm devices. In these cases, rely on magnetic navigation and external measurement for tip positioning and use chest x-ray or fluoroscopy to confirm catheter tip location, as indicated by institutional guidelines and clinical judgment. Warning: Do not rely on ECG signal detection for catheter tip positioning when there are no observable changes in the intravascular P-wave. In this case, rely on magnetic navigation and external measurement for tip positioning and use chest X-ray or fluoroscopy to confirm catheter tip location, as indicated by institutional guidelines and clinical judgment. Warning: Do not place and/or use the Sherlock 3CG* TCS in the presence of strong magnetic fields such as Magnetic Resonance Imaging (MRI) devices. The high magnetic fields created by an MRI device will attract the equipment with a force sufficient to cause death or serious injury to persons between the equipment and the MRI device. This magnetic attraction may also damage the equipment. The magnetic and the RF fields associated with the MRI environment may interfere with the display of ECG waveforms. Consult the MRI manufacturer for more information. Warning: Do not remove Sherlock 3CG* TCS enclosures. To avoid electrical shock, use only the power cord supplied with the system and connect only to properly grounded wall outlets. Only Bard Access Systems qualified personnel should service the system
