Intended Use

The Captus Vascular Retrieval System is intended for use in the cardiovascular system to retrieve foreign objects, including, but not limited to guide wires, coils, balloons, catheters, and filters.

Device Story

Captus Vascular Retrieval System is a percutaneous retrieval device used by physicians in the cardiovascular system. It consists of a 120 cm flexible PEEK and Pebax shaft with a nitinol Braided Loop Snare (BLS) at the distal end. An inner rod, secured to the BLS via UHMWPE braided suture, connects to a proximal external torquer. During procedures, the physician positions the distal end near a foreign object and rotates the torquer clockwise to cinch the BLS, securing the object for retrieval. The device facilitates the removal of misplaced or unwanted foreign bodies, reducing the need for more invasive surgical interventions.

Clinical Evidence

No clinical data. Evidence consists of bench testing and an ovine model for thrombogenicity. Bench testing included biocompatibility (cytotoxicity, sensitization, irritation, systemic toxicity, hemocompatibility, pyrogenicity) and design verification (tensile strength, torque, leak, corrosion resistance, and simulated use). A feasibility study demonstrated successful retrieval of various foreign bodies.

Technological Characteristics

Device comprises a flexible PEEK and Pebax shaft with a nitinol Braided Loop Snare (BLS) and UHMWPE braided suture. Features a proximal external torquer for mechanical cinching. Dimensions include a 120 cm shaft length. Non-powered, mechanical device. Biocompatibility and performance verified via industry standard testing protocols.

Indications for Use

Indicated for use in the cardiovascular system to retrieve foreign objects (e.g., guide wires, coils, balloons, catheters, filters) in patients requiring percutaneous retrieval.

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.

#### DEVICE DESCRIPTION

The Captus Vascular Retrieval System consists of a flexible polyetheretherketone (PEEK) and Pebax shaft with a nitinol Braided Loop Snare (BLS) on the distal end. The device is designed to

capture and retrieve foreign objects from the cardiovascular system. The lumen of the 120 cm long flexible snare shaft contains an inner rod that is secured to the BLS using an ultra-high molecular weight polyethylene (UHMWPE) braided suture. The external torquer is attached to the proximal end of the shaft and supports BLS manipulation. During the procedure, once the distal end has been positioned near the foreign object, the torquer can be turned clockwise (in relation to the shaft) in order to cinch the BLS. This feature allows the foreign object to be more firmly secured before its retrieval.

## PREDICATE DEVICE IDENTIFICATION

The Captus System is substantially equivalent to the following predicates:

| 510(k)<br>Number | Predicate Device Name / Manufacturer | Primary<br>Predicate |
|------------------|------------------------------------------------------------------|----------------------|
| K112185 | FourSnare Vascular Retrieval Snare / Cook Inc. | ✓ |
| K092343 | EN Snare Endovascular Snare System / Merit Medical Systems, Inc. | |
| K151497 | EN Snare Endovascular Snare System / Merit Medical Systems, Inc. | |

## SUMMARY OF NON-CLINICAL TESTING

No FDA performance standards have been established for the Captus System. The following tests were performed to demonstrate safety based on current industry standards:

The following tests were performed to demonstrate biocompatibility of the device: cytotoxicity, sensitization, irritation, acute systemic toxicity, hemocompatibility (direct and indirect hemolysis, complement activation, platelet and leukocyte counts, partial thromboplastin time), and material mediated pyrogenicity. Additionally, a thrombogenicity assessment of the device was performed in an ovine model.

The following tests were performed to demonstrate design verification and performance of the device: total length, outer shaft length, BLS outer working length (open), BLS outer diameter (open), BLS inner working length (open), outer shaft (outside diameter), inner shaft (outside diameter), maximum number of turns on torquer, appearance, cross-hair symmetry, distal bond tensile strength, joint strength, torque tensile strength, leak, torque location, and junction tensile strength. Corrosion resistance was performed as well as simulated use testing comparing the subject and predicate devices. A feasibility study documenting the retrieval of various foreign bodies from the vascular system was performed to demonstrate that the device is appropriate with the stated indications.

## EQUIVALENCE TO PREDICATE DEVICES

Avantec believes that the Captus System is substantially equivalent to the predicate devices based on the information summarized here:

The subject device has identical indications for use as K112185 and similar design and dimensions as the devices cleared in K092343 and K151497. It uses similar or identical materials as the devices cleared in K112185 and K151497. The subject device has similar technological characteristics to the devices cleared in K112185, K092343, and K151497 and has undergone testing to ensure the device is substantially equivalent to the predicates.

#### CONCLUSION

Based on the testing performed, including biocompatibility, design validation, corrosion testing, usability testing, and feasibility testing, it can be concluded that the subject device does not raise new issues of safety or efficacy compared to the predicate devices. The similar indications for use, technological characteristics, and performance characteristics for the proposed Captus System are assessed to be substantially equivalent to the predicate devices.
