The NeVa PV Thrombectomy Device is indicated for:

• The non-surgical removal of thrombus burden from coronary blood vessels,
• Use with adjunctive aspiration and with the injection or infusion of contrast media and other fluids.

The NeVa PV Thrombectomy Device ("NeVa") is a mechanical thrombectomy device that is temporarily inserted into the coronary vasculature under angiographic visualization in order to remove emboli and thrombus to restore blood flow to occluded vessels. The overall design of NeVa is similar to other commercially mechanical thrombectomy devices that use a self-expanding nitinol basket attached to a core pusher wire. To optimize emboli and thrombus removal, NeVa employs a capture cell design within the nitinol basket structure that incorporates a proprietary drop zone pattern. This proprietary drop zone design maximizes clot retrieval efficiency without changing the mechanism of action used by mechanical thrombectomy devices. As with other mechanical thrombectomy devices, NeVa is intended to be delivered through a compatible commercially available microcatheter to the target vessel. NeVa is intended to be retrieved into a guiding catheter with adjunctive aspiration to reduce potential emboli. NeVa is provided sterile and intended for single-use only. To accommodate different vessel diameters and clot sizes, NeVa is provided in multiple expandable tip sizes and configurations.

NeVasc Aspiration Catheter:
As part of the NeVasc Aspiration System, the NeVasc Aspiration Catheter with the Vesalio Aspiration Tubing Set and a compatible aspiration pump is indicated for use in the revascularization of patients with acute ischemic stroke secondary to intracranial large vessel occlusive disease (within the internal carotid, middle cerebral - M1 and M2 segments, basilar, and vertebral arteries) within 8 hours of symptom onset. Patients who are ineligible for thrombolytic drug therapy or who failed thrombolytic drug therapy are candidates for treatment.

Vesalio Aspiration Tubing Set:
As part of the NeVasc Aspiration System, the Vesalio Aspiration Tubing Set is indicated to connect the NeVasc Aspiration Catheter to a compatible aspiration pump.

The NeVasc Aspiration System consists of 1) NeVasc Aspiration Catheter, 2) Peel Away Introducer Sheath and 3) Vesalio Aspiration Tubing Set.

The NeVasc Aspiration Catheter is a single-lumen, reinforced, flexible, variable stiffness composite catheter that facilitates the removal of thrombus from the neurovasculature when connected to a compatible aspiration pump and the Vesalio Aspiration Tubing Set. The catheter distal shaft has an external hydrophilic coating aimed at reducing friction during use. The distal end of the catheter shaft is radiopaque for fluoroscopic visualization, and the proximal end contains a luer hub that allows attachment of accessories for flushing and aspiration.

The peel-away introducer sheath is provided in the package to facilitate the insertion of the NeVasc Aspiration Catheter's distal tip into an appropriate vascular sheath.

The Vesalio Aspiration Tubing Set is provided in a separate package and is made of common medical grade polymers. It comprises of a hollow cylindrical tube that is bonded to a standard male rotator fitting on one end. The male rotator allows the tubing to connect to a rotating hemostasis valve (RHV) or the female luer hub of the NeVasc Aspiration Catheter. The other end of the tubing consists of a hose fitting to enable connection with an aspiration pump. A flow switch is connected in line to provide vacuum control.

The NeVasc Aspiration System is provided sterile, non-pyrogenic, and is intended for single use only.

The Vesalio Peripheral Catheter is intended for use in the peripheral arterial vasculature for:

• the removal of fresh, soft emboli and thrombi
• infusion of diagnostic agents, such as contrast media

The Vesalio Peripheral System consists of 1) Peripheral Catheter, 2) Peel away Introducer Sheath and 3) an Aspiration Tubing Set.

The Peripheral Catheter is a single-lumen, coil-reinforced, flexible, variable stiffness composite catheter that facilitates the removal of thrombus from the peripheral arterial vasculature when connected to a compatible aspiration pump and the Aspiration Tubing Set.

The catheter is a hollow cylindrical tube constructed using a combination of medical-grade polymers with metal reinforcement, a lubricous inner liner made from PTFE and the outer jacket consisting of thermoplastics made of polyurethane, polyether block amide, and nylon 12. The distal end of the catheter has a hydrophilic coating aimed to reduce friction and aid tracking through the vasculature. The catheter employs radiopaque characteristics for angiographic visualization.

On the proximal end, the catheter incorporates a flexible strain relief, which provides kink resistance, and a translucent, polycarbonate female luer hub to allow attachment of ancillary devices for navigation, infusion of fluids, and aspiration through the catheter.

A peel-away introducer sheath is provided in the package to facilitate the insertion of the Peripheral Catheter's distal tip into an appropriate vascular sheath.

The Aspiration Tubing Set is provided in a separate package and is made of common medical grade polymers. It comprises of a hollow cylindrical tube that is bonded to a standard male rotator fitting on one end. The male rotator allows the tubing to connect to an RHV or the female luer hub of the catheter. The other end of the tubing consists of a hose fitting to enable connection with a vacuum pump. A flow switch is connected in line to provide vacuum control. The Peripheral System is provided sterile, non-pyrogenic, and is intended for single use only.

The NeVa™ PV Thrombectomy Device is indicated for:

• The non-surgical removal of emboli and thrombi from peripheral blood vessels.
• Temporary use in peripheral vessel occlusion.
• Use with aspiration and with the injection or infusion of contrast media and other fluids.

The NeVa™ PV Thrombectomy Device is a sterile, single-use thrombectomy device designed to for use in the peripheral vasculature to restore blood flow via non-surgical removal of emboli and thrombi from peripheral vessels in the vasculature. The NeVa™ PV device consists of a self-expanding nitinol basket attached to a core pusher wire that can be delivered through a micro catheter, deployed across a clot, and then removed with the clot to enable revascularization of the occluded vessel. To aid in fluoroscopic visualization, radiopaque markers are positioned at the distal end, proximal end, and along the nitinol basket of the NeVa™ PV device. A flexible atraumatic soft tip attached to the distal end of the nitinol basket is radiopaque for enhanced fluoroscopic visualization.

The NeVaTM PV device is provided sterile and is intended for single patient use. The device is not intended to be re-sterilized or re-used. No accessories are provided with the NeVaTM PV device. The device is intended to be used in conjunction with the appropriately sized microcatheter as indicated in the proposed Instructions for Use.

The provided text describes the regulatory clearance of a medical device, the NeVa™ PV Thrombectomy Device, based on its substantial equivalence to a predicate device. It details the device's characteristics, indications for use, and a summary of nonclinical testing performed to demonstrate its performance. However, the document does not contain information about acceptance criteria for a study, nor does it detail a study that proves the device meets specific acceptance criteria in the context of an algorithm or AI performance.

The document is for a medical device clearance (510(k)) that relies on substantial equivalence to a predicate device (ReVive™ PV Thrombectomy Device), not on meeting specific quantitative performance metrics as one might see for an AI/algorithm-based medical device.

Therefore, I cannot provide the requested information for acceptance criteria and a study proving device performance in the context of AI/algorithm evaluation. The document focuses on the physical and functional performance of a mechanical thrombectomy device.

To directly address your request given the provided text, I must state that the information is not present in the provided regulatory submission.
