Penumbra is committed to delivering clinically beneficial products that help patients suffering from stroke and other neurovascular diseases.
®
The Penumbra System uses a unique Microcatheter and Separator™ based thrombus debulking approach to intracranial revascularization. Together with the Penumbra Aspiration Pump and Accessories, its advantages include: • Proximal working position • Continuous aspiration • Variable sizing for variable anatomy 3

Technical Tip: The Neuron 6F 070 Delivery Catheter placed in the petrous anatomy may facilitate access. The Neuron 6F 070 is compatible with the 026, 032 and 041 Reperfusion Catheters only. TM
Technical Tip: Steam shaping of the Reperfusion Catheter Tip may assist tracking. All Penumbra Reperfusion Catheters are steam shapable. Technical Tip: Coaxial technique may require that RHV be removed from 041 Reperfusion Catheter and 054 Reperfusion Catheter to allow microcatheter to extend far enough to aid in access.

Prepare Penumbra System® for Aspiration 1
Place Reperfusion Catheter in vessel immediately proximal to occlusion. If the coaxial system was used, re-attach the RHV on to the Reperfusion Catheter hub.
2
Remove Guidewire from the Reperfusion Catheter.
3
Introduce matching Separator using light blue colored Penumbra introducer.
4
Set up the Separator for optimal throw within the Reperfusion Catheter. a. Place a torque device on proximal end of Separator. b. Tighten torque device against the RHV hub so that radiopaque marker on Separator Bulb extends approximately 4mm past the radiopaque marker on the Reperfusion Catheter.

2 Observe and note baseline aspiration flow rate in
both the Aspiration Tubing (sterile) and dripping in the Canister.
3 Position Separator such that the radiopaque marker on the Separator is approximately 4mm distal to the radiopaque marker on the Reperfusion Catheter. Separator movement should be kept short enough (<2cm) so that the Separator’s midshaft (green in color) does not exit RHV.
4 Ingest Clot: Advance Reperfusion Catheter until aspiration flow slows or stops in the Aspiration Tubing (sterile) and/or the pump Canister.
Increased friction between Separator and Reperfusion Catheter may indicate thrombus has become lodged in one or both devices. Remove and thoroughly clean both devices. If friction or fatigue persists, replace one or both with new devices. See “Tips” on page 18.

Aspiration Optimization Techniques 1
Reperfusion Catheter Does Not Clear After Several Separator Movements If after one (1) minute of performing the procedure in steps 4-6 above under Thrombus Removal, the Reperfusion Catheter cannot be cleared, and aspiration flow cannot be re-established, perform the following to help clear the Reperfusion Catheter: a. Retract the tip of the Reperfusion Catheter proximal to the thrombus to an open segment of the artery. b. Repeat the movement of the Separator as in steps 4-6 above in Thrombus Removal. c. If flow is still not re-established, remove Separator from the Reperfusion Catheter and inspect, and wipe down any adherent material.
d. If flow is not re-established after removing the Separator, the Reperfusion Catheter should be removed, inspected for damage, flushed on the table, or replaced. e. The system should be re-introduced as described in Access Guidelines on Page 10.

Aspiration Optimization Techniques
2 Reperfusion Catheter is Unable to Maintain Stable Position at Proximal Face of Thrombus If the Reperfusion Catheter is unable to maintain a stable position at the proximal surface of the thrombus, you may elect to move to a more distal position. a. Place the Reperfusion Catheter within the thrombus using standard access techniques. b. Begin aspirating. c. Use the Separator to clear the Reperfusion Catheter as discussed in steps 4-6 above in Thrombus Removal. Technical Tip: The Reperfusion Catheter may need to be repositioned proximal to thrombus in an open vessel to achieve optimal aspiration of ingested clot.
