Intended Use

The Sonicath Ultra Imaging Catheter is intended for the ultrasound examination of peripheral and coronary intravascular pathology. Intravascular ultrasound imaging is indicated in patients who are candidates for transluminal interventional procedures.

Device Story

Sonicath Ultra Imaging Catheter is a sterile, single-use disposable device for intravascular ultrasound (IVUS) imaging. Device consists of a catheter body and an imaging core containing a high-torque, flexible, rotating drive cable with an outward-looking 20 MHz ultrasonic transducer at the distal tip. Operated by physicians in clinical settings during transluminal interventional procedures. Device captures real-time ultrasound images of intravascular pathology in coronary and peripheral vasculatures. Output is displayed for clinician visualization to assist in assessing vessel pathology and guiding interventional decision-making. Benefits include improved visualization of vascular structures to support procedural success.

Clinical Evidence

No clinical data provided. Evidence consists of bench testing (tensile strength of catheter joints and imaging core weld joints), acoustic output testing (verified below FDA Track 1 limits), animal testing (in-vivo functional and imaging characteristics), and biocompatibility testing (ISO 10993-1).

Technological Characteristics

20 MHz ultrasonic transducer; rotating drive cable imaging core; 2.9F and 3.2F catheter diameters; sterile, single-use disposable; biocompatible materials per ISO 10993-1; acoustic output compliant with FDA 1993 guidance.

Indications for Use

Indicated for patients who are candidates for transluminal interventional procedures requiring ultrasound examination of peripheral and coronary intravascular pathology.

Regulatory Classification

Identification

A diagnostic ultrasonic transducer is a device made of a piezoelectric material that converts electrical signals into acoustic signals and acoustic signals into electrical signals and intended for use in diagnostic ultrasonic medical devices. Accessories of this generic type of device may include transmission media for acoustically coupling the transducer to the body surface, such as acoustic gel, paste, or a flexible fluid container.

## Intended Use:

The Sonicath Ultra Imaging Catheter is intended for the ultrasound examination of peripheral and coronary intravascular pathology. Intravascular ultrasound imaging is indicated in patients who are candidates for transluminal interventional procedures.

## Comparison To Predicate Devices:

The BSC Sonicath Ultra Imaging Catheter is a sterile, single-use disposable device used for the ultrasound examination of intravascular pathology in both the coronary and peripheral vasculatures. The Sonicath Ultra 2.9 F and 3.2 F Imaging Catheters and predicate devices consist of two main components: (1) the catheter body and (2) the imaging core. The imaging core of both the Sonicath Ultra and the predicate device imaging catheters is comprised of a hi-torque, flexible, rotating drive cable with an outward looking ultrasonic transducer at the distal tip.

The Sonicath Ultra Imaging Catheter is equivalent in intended use, design and operational characteristics to the following devices: (1) BSC, Sunnyvale - MicroView 2.9 F Coronary Imaging Catheter, (2) BSC, Sunnyvale - MicroRail 3.2 F Coronary Imaging Catheter, and (3) BSC, Natick (Medi-tech)- Sonicath 3.5 F Interventional Ultrasound Imaging Catheter. All predicate devices are used for the ultrasound imaging of intravascular pathology in either the coronary or peripheral vasculature. The Sonicath Ultra Imaging combines various features of the predicate devices to allow for imaging in both the peripheral and coronary vasculature.

# 510(k) Summary of Safety and Effectiveness (continued)

## Non-Clinical Test Results:

Bench, acoustic output, animal and biocompatibility testing demonstrate that the BSC, Sonicath Ultra Imaging Catheter is safe and effective, while meeting the anticipated clinical requirements for its intended use.

## Bench Testing:

Bench testing was included to evaluate the physical integrity of the catheter shaft by testing the tensile strength of the catheter joints and shaft tubing. The catheter joint and shaft tubing strengths were determined to be acceptable and consistent with the intended use of the device. In addition, the physical integrity of the imaging core was examined by evaluating the tensile strengths of the weld joints. The imaging core weld joint strengths were also determined to be acceptable and consistent with the intended use of the device.

## Acoustic Output Testing:

The Sonicath Ultra Imaging Catheter was tested for acoustic output as described in the FDA Guidance, The Revised 510(k) Diagnostic Ultrasound Guidance for 1993, Food and Drug Administration, and the 510(k) Guide for Measuring and Reporting Acoustic Output of Diagnostic Ultrasound Medical Devices, December, 1985, Food and Drug Administration. Acoustic output test results for the Sonicath Ultra 2.9 F and 3.2 F Imaging Catheters are below the FDA Track 1 limits.

## Animal Testing:

Animal testing was performed to assess the in-vivo functional and imaging characteristics of the catheter. In conclusion, the performance of the Sonicath Ultra Imaging Catheters was consistent with the intended clinical use of the device.

## Biocompatibility

The materials used to fabricate the BSC, Sonicath Ultra Imaging Catheter are similar to the predicate devices. The Sonicath Ultra Imaging Catheter was subjected to biocompatibility testing and meets the requirements for biocompatibility testing outlined in ISO 10993-1 Part 1 "Biological Evaluation of Medical Devices".

## Summary:

Based on the intended use, design, performance and biocompatibility data provided in this Notification, BSC, Sonicath Ultra Imaging Catheters have been shown to be substantially equivalent to currently marketed predicate devices.

Dear Mr. Wong:

We have reviewed your section 510(k) notification of intent to market the device referenced above and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug and Cosmetic Act. You may, therefore, market the device, subject to the general controls provisions Act (Act). The general controls provisions of the Act include requirements for registration, listing of devices, good manufacturing practices, labeling, and prohibitions against misbranding and adulteration.

This determination of substantial equivalence applies to the following transducers intended for use with the BSC Sonicath Ultra™ Imaging Catheters, as described in your premarket notification:

**Transducer Model Number**
2.9F and 3.2F/20 MHZ

If your device is classified (see above) into either class II (Special Controls) or class III (Premarket Approval) it may be subject to such additional controls. Existing major regulations affecting your device can be found in the *Code of Federal Regulations*, Title 21, Parts 800 to 895. A substantially equivalent determination assumes compliance with the Good Manufacturing Practice for Medical Devices: General (GMP) regulation (21 CFR Part 820) and that, through periodic GMP inspections, the FDA will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, the Food and Drug Administration (FDA) may publish further announcements concerning your device in the *Federal Register*. *Please note*: this response to your premarket notification does not affect any obligation you may have under sections 531 and 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal laws or regulations.

This determination of substantial equivalence is granted on the condition that prior to shipping the first device, you submit a postclearance special report. This report should contain complete information, including acoustic output measurements based on production line devices, requested in Appendix G, (enclosed) of the Center’s February 17, 1993 “Revised 510(k) Diagnostic Ultrasound Guidance for 1993.” If the special report is incomplete or contains unacceptable values (e.g., acoustic output greater than approved levels), then the 510(k) clearance may not apply to the production units which as a result may be considered adulterated or misbranded.

The special report should reference the manufacturer’s 510(k) number. It should be clearly and prominently marked “ADD-TO-FILE” and should be submitted in duplicate to:

Food and Drug Administration
Center for Devices and Radiological Health
Document Mail Center (HFZ-401)
