The Penumbra System is designed to remove thrombus and restore blood flow in the neurovasculature using aspiration. The Reperfusion Catheter delivers aspiration from the pump directly to the site of occlusion to remove the clot. The 3D Revascularization Device is used with Reperfusion Catheters to facilitate aspiration and removal of the thrombus when needed. Alternatively, a Separator may be used to clear the lumen of the Reperfusion Catheter should it become blocked with thrombus. The Reperfusion Catheter is introduced through a guide catheter or long femoral sheath and into the intracranial vasculature and guided over a neurovascular guidewire to the site of the primary occlusion. The Penumbra Reperfusion Catheter is used with the Penumbra Aspiration Pump to aspirate thrombus from an occluded vessel. The Penumbra Reperfusion Catheter is connected to the Penumbra Aspiration Pump using the Penumbra Aspiration Tubing and the Penumbra Aspiration Pump Canister. The Penumbra Reperfusion Catheter is provided with a steam shaping mandrel, rotating hemostasis valve (RHV), peelable sheath, and optionally, SENDit Technology (cleared under K191946). The Penumbra 3D Revascularization Device is provided with an introducer sheath. The Penumbra Separator is provided with an introducer and torque device. The devices are visible under fluoroscopy.

1.8 Conclusions
The subject Penumbra System (Reperfusion Catheter RED 72) is substantially equivalent to the predicate Penumbra System (Reperfusion Catheter RED 72). The subject device has the identical intended use and similar operating principle, design concept, fundamental technology as the predicate. The differences between the subject and predicate devices do not raise new or different questions of safety or effectiveness. The device testing described in this 510(k) Summary demonstrates the subject device performs as intended.
