Intended Use

The Pounce Thrombectomy System is intended for the non-surgical removal of thrombi and emboli from the peripheral arterial vasculature. The Pounce LP Thrombectomy System is indicated for use in vessels ranging from 2 mm in diameter.

Device Story

Percutaneous catheter system for mechanical thrombus removal in peripheral arterial vasculature; used by physicians in clinical settings. System components: delivery catheter, basket wire with two self-expanding baskets, funnel catheter, cleaning tools. Physician delivers basket wire to thrombus site via delivery catheter; baskets capture thrombus; funnel catheter collects and retrieves thrombus. Radiopaque markers on basket struts and catheter tip provide fluoroscopic visualization. System introduced through guide sheath. Benefits include non-surgical thrombus removal, potentially restoring blood flow in peripheral arteries.

Clinical Evidence

No clinical data. Substantial equivalence supported by bench testing, including dimensional, radial force, tensile strength, kink, leak, fatigue, simulated use, radiopacity, and biocompatibility testing.

Technological Characteristics

Percutaneous catheter system; includes delivery catheter, basket wire with self-expanding baskets, and funnel catheter. Features radiopaque markers for fluoroscopic guidance. Components are flexible; includes integrated handle with slider button for funnel deployment. Biocompatible materials used. Sterilized device.

Indications for Use

Indicated for non-surgical removal of thrombi and emboli from peripheral arterial vasculature in vessels 2 mm to 4 mm in diameter.

Regulatory Classification

Identification

An embolectomy catheter is a balloon-tipped catheter that is used to remove thromboemboli, i.e., blood clots which have migrated in blood vessels from one site in the vascular tree to another.

Dear Holly Ramirez:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate 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 (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls.

Image /page/4/Picture/0 description: The image shows the logo for Surmodics. The logo consists of a stylized blue and green icon to the left of the company name, "SURMODICS," which is written in a simple, sans-serif font. The icon appears to be an abstract representation of folded or layered shapes, with the blue color dominating and a touch of green at the bottom. The overall design is clean and modern.

# Device Description

The Surmodics Pounce™ Thrombectomy System is a percutaneous catheter system designed to facilitate mechanical thrombus removal in the peripheral arterial vasculature. The system is comprised of three separate components: a Delivery Catheter, a Basket Wire, the Funnel Catheter, and cleaning tool accessories. The system contains radiopaque components to conduct the procedure and is intended to be introduced through appropriately sized guide sheath.

The Delivery Catheter is flexible and designed to deliver the Basket Wire to the location of the thrombus. Incorporated in the catheter is a radiopaque marker band located at the distal tip.

The Basket Wire is comprised of two distal self-expanding baskets mounted a core wire for capturing thrombus. The distal capture baskets have integral radiopaque markers mounted on the struts of the basket for basket visibility under fluoroscopy.

The Funnel Catheter is used for thrombus collection and retrieval in conjunction with the Basket Wire. The Funnel Catheter is comprised of an inner funnel catheter and an outer delivery catheter. The two catheters work together to allow unsheathing of the funnel using the slider button on the integrated handle.

#### Indication for Use

The Pounce™ Thrombectomy System is intended for the non-surgical removal of thrombi and emboli from the peripheral arterial vasculature.

The Pounce LP Thrombectomy System is indicated for use in vessels ranging from 2 mm to 4 mm in diameter.

### Comparison of Technological Characteristics

The Pounce LP Thrombectomy System is substantially equivalent to the previous Pounce Thrombectomy System (K220501) in design, intended use, principles of use, biocompatibility, sterility, and labeling. Changes to the predicate device that have led to the submission of this new 510(k) are to extend the product line to include the use in vessels ranging from 2 mm. The smaller basket wire and catheter size has been verified through performance bench and biocompatibility testing and determined to be substantially equivalent.

The abstract shape appears to be a stylized ribbon or folded paper design, with the blue portion on top and the green portion underneath.

# Performance Bench Testing

Results of design verification and biocompatibility testing demonstrates that the technological and material differences identified do not raise new questions of safety or effectiveness compared to the predicate device. The Pounce LP Thrombectomy System has been evaluated through the following tests:

- -Dimensional
- Radial Force -
- -Tensile Strength
- -Kink
- -Air and Liquid Leak
- Basket Wire Fatigue -
- -Atraumatic Surfaces
- -Simulated Use
- Removal Force -
- -Radiopacity
- -Luer Compatibility
- Ancillary Device Compatibility -
- Torque Strength -
- -Rated Burst Pressure
- -Coating Integrity
- Packaging/Distribution -
- -Biocompatibility

# Clinical Studies and Testing

No clinical studies were required for the Pounce Thrombectomy System.

# Conclusion

Based on the device description, materials, technological characteristics, and accompanying performance and biocompatibility data it can be concluded that the device modifications made to the Pounce LP Thrombectomy System are substantially equivalent to the predicate device and the device will continue to function per its intended use.
