{4}------------------------------------------------

# Device Description, continued

The catheter body consists of four sections: the telescope assembly, proximal shaft, distal shaft, and the distal quidewire lumen. The proximal shaft, distal shaft, and distal quidewire lumen comprise the usable length of the catheter (135 cm). The proximal telescoping section remains outside of the guide catheter.

The distal quidewire lumen (1.6 cm in length) is used to track the catheter along the quidewire and incorporates a radiopaque marker band (0.5 cm from the distal tip). The distal shaft serves as a flexible and acoustically transparent imaging window. The proximal shaft provides pushability to the catheter and serves as a lumen to the imaging core. Two insertion markers are located on the proximal shaft (90 and 100 cm from the distal tip). These markers facilitate estimation of catheter position relative to the distal tip of the guide catheter.

The telescope assembly allows the imaging core to be advanced and retracted up to 15 cm. The corresponding movement of the transducer occurs within the imaging window from 2 to 17 cm from the distal tip of the catheter. The telescoping shaft includes 16 incremental markers (1 cm apart) for lesion length assessment; the 5-cm, 10-cm, and 15-cm markers are distinct. The outer surface of the catheter body also employs a hydrophilic coating to enhance lubricity and promote deliverability (distal 23 cm).

The imaging core consists of a proximal hub assembly and a rotating drive cable that houses a piezoelectric (PZT) transducer at the distal imaging window. The hub assembly (1) provides an electro-mechanical interface between the catheter and the motor drive unit and (2) incorporates a oneway check valve that is used to flush the interior of the catheter body. The catheter must be flushed with heparinized saline prior to use, as this provides the acoustic coupling media required for ultrasonic imaging.

The drive cable and PZT transducer rotate independently of the sheath to provide 360° image resolution. The transducer converts electrical impulses sent by the motor drive in to transmittable acoustic energy. Reflected ultrasound signals are converted back to electrical impulses, returned to the motor drive unit, and are ultimately processed by the iLab equipment for visualization.

| Device<br>Technoogy<br>Characteristics<br>and<br>Comparison to<br>Predicate<br>Device | OptiCross™ 18 maintains the same indications for use,<br>fundamental scientific technology, and operating principles<br>as those of the predicate device (Atlantis™ 018, K073623). |
|---------------------------------------------------------------------------------------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| | OptiCross 18 serves as the replacement for BSC's legacy<br>peripheral imaging catheter, Atlantis 018, but with the latest<br>proximal hub interface (and with it compatibility with the<br>MDU5 PLUS Motor Drive Unit) – as already utilized by BSC's<br>OptiCross™ (K123621) and OptiCross™ 6 (K153617)<br>Coronary Imaging Catheters. Likewise, other modifications<br>to Atlantis 018 include utilization of BSC's latest sheath and<br>telescope designs presently employed by OptiCross™ 6. |
| | In addition to adopting the latest hub, telescope, and sheath<br>designs as described above; OptiCross 18 utilizes a lower<br>frequency (30 MHz) transducer intended to enhance depth of<br>penetration relative to the predicate, Atlantis 018 (40 MHz).<br>Finally, OptiCross™ 18 will be sterilized via electron beam<br>(E-Beam) irradiation; not gamma, a practice now consistent<br>for all BSC Imaging Catheters. |
| | In support of a substantial equivalence determination, BSC<br>has compared and evaluated the material and design<br>differences between the subject and predicate device. |
| | Non-clinical performance evaluations, as described below,<br>indicate that the subject device is substantially equivalent to,<br>and at least as safe and effective as the predicate device<br>(Atlantis 018). |

{6}------------------------------------------------

| Non-Clinical<br>Performance<br>Data | Determination of substantial equivalence is based on an<br>assessment of non-clinical performance data. |
|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| | Non-clinical data includes bench-top performance testing,<br>packaging validation, biological safety, electromagnetic<br>compatibility, acoustic output testing, and a pre-clinical<br>animal study to validate imaging performance in the porcine<br>model. |
| | Bench Testing:<br>Bench testing was performed to evaluate physical integrity,<br>functionality, and overall performance of the catheter.<br>Performance criteria includes deliverability, crossability,<br>guide catheter compatibility, lubricity, retraction capability,<br>image resolution, image penetration, non-uniform rotational<br>distortion (NURD), measurement accuracy, pullback<br>reliability, dimensional requirements, visibility under<br>fluoroscopy, interface with ancillary devices, environmental<br>requirements, user interface requirements, catheter<br>robustness and simulated use structural integrity. |
| | Pre-clinical Evaluation:<br>The purpose of this study was to support acute performance<br>and design validation claims associated with in-vivo image<br>quality. |
| | Biological Safety Testing:<br>OptiCross™ 18 was subjected to a series of biocompatibility<br>tests in accordance with ISO 10993-1, microbial<br>assessments including bioburden and endotoxin,<br>pyrogenicity, and sterility assurance. |
| | Electrical and Mechanical Safety:<br>Acoustic Output was evaluated in accordance with FDA<br>Guidance, Information for Manufacturers Seeking Marketing<br>Clearance of Diagnostic Ultrasound Systems and<br>Transducers (September 9, 2008). Acoustic Output test<br>results for OptiCross™ 18 are below the FDA Track 1 limits.<br>Electromagnetic compatibility testing was also conducted;<br>demonstrating compliance to IEC 60601-1-2 (3rd Edition). |
| | Packaging Validation:<br>The integrity of the packaging configuration was evaluated in<br>accordance with ISO 11607-1 and ISO 11607-2. Testing<br>was conducted on fully packaged units after subjected to<br>electron beam sterilization, climatic conditioning, and<br>distribution challenge conditioning. |
| Conclusion:<br>Non-clinical performance evaluations, as described above,<br>indicate that the subject device is substantially equivalent to,<br>and at least as safe and effective as the predicate device, | |

Atlantis™ 018 (K073623).

|---------------------------------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| Conclusion | With respect to the predicate, design modifications<br>incorporated by OptiCross™ 018 do not alter the<br>fundamental scientific technology or the indications for use.<br>Based on Failure Mode Effects Analysis (FMEA),<br>comprehensive verification and validation activities were<br>successfully completed; raising no new issues of safety or<br>effectiveness.<br><br>Non-clinical performance data supports a determination that<br>the subject device, OptiCross™ 18, is substantially<br>equivalent to the predicate device, Atlantis™ 018 (K073623);<br>and that it is at least as safe and effective for its intended<br>use. |
