# IV. DEVICE DESCRIPTION
The Powered Aventus Thrombectomy System™ (ATS-P) is a catheter-based aspiration system designed for minimally invasive removal of emboli and thrombi from blood vessels. It is also indicated for injection, infusion, and/or aspiration of contrast media and other fluids into or from a blood vessel. The ATS-P is intended for use in the peripheral vasculature. The ATS-P is a single-use device that is provided sterile and resides within the sterile field.
The ATS-P is comprised of the following components:
- Thrombectomy Catheter
- Clot Management System
The Thrombectomy Catheter is a percutaneous device that is inserted into the patient anatomy via venous access to engage and remove thromboemboli via aspiration. The Thrombectomy Catheter is available in four (4) models differentiated by profile, tip shape (Max vs Sweep), and working length to enhance physician product selection based on patient anatomy within the vasculature. Each model is compatible with off-the-shelf 0.035" guidewires and includes a flexible hydrophilic coated catheter, atraumatic Distal Tip, a Catheter Body, and a Handle, designed to navigate within the vasculature without the need of a dilator. The 24F device is provided with an integrated Navigation Catheter.
- 24Fr x 92cm length – Max Tip

The Thrombectomy Catheter includes embedded electronics and software which provide supplemental information about material sensed at the Thrombectomy Catheter tip via Sensing Indicators on the catheter handle and Clot Management System. The sensing functionality is meant for continuous operation throughout the procedure.
The Clot Management System is used in conjunction with the Thrombectomy Catheter to generate aspiration force at the catheter tip and power the Sensing Indicators and sensing functionality. The Clot Management System includes the Aspiration Syringe, Clot Canister, CO₂ Cartridge, De-Airing Chamber, and Blood Disposal Line. Upon actuation of the aspiration mechanism, the Syringe plunger retracts to a user determined aspiration volume (15 / 30 / 60-cc) then advances, pushing aspirated contents into the Clot Canister which separates clot and blood via a strainer and dual layered mesh filter (200 and 40 microns). The blood then passes through a De-Airing Chamber into the Blood Disposal Line for collection and disposal.
# V. INDICATIONS FOR USE
The Powered 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 Powered Aventus Thrombectomy System is intended for use in the peripheral vasculature.
# VI. COMPARISON OF TECHNOLOGICAL CHARACTERISTICS WITH THE PREDICATE DEVICE
The subject device, Powered Aventus Thrombectomy System™, is substantially equivalent to the predicate, Aventus Thrombectomy System cleared under K253925. The intended use of the subject device is the same as the predicate, namely removal of thrombi or emboli and infusion, and/or aspiration of contrast media and other fluids into or from a blood vessel. The devices are both used in the peripheral vasculature. However, the Powered Aventus Thrombectomy System is not indicated for use in the pulmonary artery or to treat pulmonary embolism.
The subject and predicate devices share the same technological characteristics in that both devices are single patient use, large bore catheters which utilize an aspiration syringe to remove thrombi and emboli. Both the subject and predicate device incorporate disposable powered electronics and embedded software. From a manufacturing standpoint, both devices utilize shafts made with metallic (stainless steel) reinforced polymeric jackets with variable stiffness, radiopaque markings at the distal tip for fluoroscopic visualization, and use of stopcocks to direct the flow of fluids.
The subject device removes thrombi and emboli by creating a negative pressure differential and pulling back a plunger on a large bore syringe using pneumatics versus the predicate device which is done manually.
# VII. PERFORMANCE DATA
The following performance data were provided in support of the substantial equivalence determination.
