Intended Use
The Aventus Thrombectomy System is indicated for: · The non-surgical removal of emboli and thrombi from blood vessels. · Injection, infusion, and/or aspiration of contrast media and other fluids into or from a blood vessel. The Aventus Thrombectomy System is intended for use in the peripheral vasculature.
Device Story
Aventus Thrombectomy System is a manual aspiration catheter system for minimally invasive removal of emboli/thrombi from peripheral vasculature. System components include an aspiration catheter with radiopaque distal tip, navigation catheter, infusion lumen, handle, 60-cc dual-action manual syringe, and clot canister. Physician operates device under fluoroscopic guidance; catheter is navigated to target site using 0.035" guidewires. Manual syringe provides vacuum for aspiration, drawing blood and clot into canister; infusion lumen allows contrast/fluid delivery. Device facilitates clot removal, potentially restoring blood flow and improving patient outcomes. Used in clinical settings; single-use; sterile.
Clinical Evidence
No human clinical data. Evidence includes successful bench testing (tensile strength, pressure/leak integrity, clot removal validation, torque, kink testing, simulated-use) and a GLP chronic large animal study demonstrating safety and performance meeting all pre-defined endpoints.
Technological Characteristics
Catheter-based manual aspiration system. Materials: stainless steel reinforcement, polymeric jacket with variable stiffness. Features: radiopaque distal tip, 60-cc dual-action manual syringe, clot canister. Compatible with 24F introducer sheaths, 4F support catheters, 0.035" guidewires. Sterilization: ISO 14937:2009 compliant (SAL 10^-6). Biocompatibility: ISO 10993-1:2018. Non-software device.
Indications for Use
Indicated for non-surgical removal of emboli and thrombi from peripheral vasculature and injection, infusion, or aspiration of contrast media and fluids in patients requiring such procedures.
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.

a Handle designed to navigate within the vasculature. The Aspiration Catheter shaft incorporates a metallic reinforcement made of stainless steel, an inner liner and polymeric jacket material with variable stiffness.
The System is provided with a 60-cc dual action manual syringe which allows for directional flow control and directs aspirated blood and clot into the Clot Canister.
#### V. INDICATIONS FOR USE
The Aventus Thrombectomy System is indicated for:
- . The non-surgical removal of emboli and thrombi from blood vessels.
- Injection, infusion, and/or aspiration of contrast media and other fluids into or from a blood . vessel.
The Aventus Thrombectomy System is intended for use in the peripheral vasculature.
### VI. COMPARISON OF TECHNOLOGICAL CHARACTERISTICS WITH THE PREDICATE DEVICE
The subject device, Aventus Thrombectomy System, is substantially equivalent to the predicate device: Malibu Aspiration Catheter cleared under K223929. The intended use of the subject device is the same as the predicate, namely removal of thrombi or emboli from the peripheral vasculature system and injection, infusion, and/or aspiration of contrast media and other fluids into or from a blood vessel.
The subject and predicate device share similar technological characteristics in that both devices are large bore aspiration catheters which utilize a 60-cc manual syringe as the aspiration source. Both devices utilize a dedicated infusion port for injection and infusion of contrast media and other fluids into or from the blood vessel. Both devices utilize similar construction such as metallic (stainless steel) reinforcement and a polvmeric jacket with variable stiffness for the shaft, radiopaque markings at the distal tip for fluoroscopic visualization, and use of flow-control valves to direct the flow of fluids.
The subject device differs from the predicate device in that it incorporates additional features that increase the convenience of use and does not include any coating or surface materials like the predicate device.
#### VII. PERFORMANCE DATA
The following performance data were provided in support of the substantial equivalence determination.
