The Penumbra System® is a fully-integrated system designed specifically for mechanical thrombectomy by aspiration. It is intended for use in the revascularization of patients with acute ischemic stroke secondary to intracranial large vessel occlusion. The Penumbra System includes Reperfusion Catheters, Hi-Flow Aspiration Tubing, and Pump MAX™ aspiration pump and its accessories.
Penumbra Pump MAX, together with the MAX Canister, is connected to the Penumbra Reperfusion Catheter using Penumbra Hi-Flow Aspiration Tubing. The Hi-Flow Aspiration Tubing connects the canister to the Penumbra Reperfusion Catheter in the sterile field. Pump MAX is capable of delivering and maintaining nearly pure vacuum of 29 inHg (98.2 kPa).
Caution: Federal (USA) law restricts this device to sale by or on the order of a physician. Prior to use, please refer to the Instructions for Use for Penumbra System and Pump MAX for complete product indications, contraindications, warnings, precautions, potential adverse events and detailed instructions for use.
Indication For Use
Penumbra System® Reperfusion Catheters and Separators
As part of the Penumbra System®, the Reperfusion Catheters and Separators are 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.
Penumbra Aspiration Tubing
As part of the Penumbra System, the Penumbra Sterile Aspiration Tubing is indicated to connect the Penumbra Reperfusion Catheters to the Penumbra Pump MAX™.
There are no known contraindications.
• The Penumbra System should only be used by physicians who have received appropriate training in interventional neuro-endovascular techniques and treatment of acute ischemic stroke.
• Do not advance, retract or use any component of the Penumbra System against resistance without careful assessment of the cause using fluoroscopy. If the cause cannot be determined, withdraw the device or system as a unit. Unrestrained torquing or forced insertion of the catheter or separator against resistance may result in damage to the device or vessel.
• Do not use the Penumbra System with a pump other than the Penumbra Aspiration Pump.
• The device is intended for single use only. Do not resterilize or reuse. Resterilization and/or Reuse may result in ineffective catheter coating lubrication, which may result in high friction and the inability to access the target neuro vasculature location.
• Do not use kinked or damaged devices. Do not use open or damaged packages. Return all damaged devices and packaging to the manufacturer/distributor.
• Use prior to the “Use By” date.
• Use the Penumbra System in conjunction with fluoroscopic visualization.
• Maintain a constant infusion of appropriate flush solution.
• When performing aspiration, ensure the Penumbra Aspiration Tubing valve is open for only the minimum time needed to remove thrombus. Excessive aspiration or failure to close the Penumbra Aspiration Tubing valve when aspiration is complete is not recommended.
• The Penumbra Separator is not intended for use as a neurovascular guidewire. If repositioning of the Penumbra Reperfusion Catheter is necessary during the revascularization procedure, such reposition should be performed over an appropriate neurovascular guidewire using standard microcatheter and guidewire techniques.
• Do not use automated high-pressure contrast injection equipment with the Penumbra Reperfusion Catheter because it may damage the device.
• Administration of anticoagulants and antiplatelets should be suspended until 24 hours post-treatment. Medical management and acute post stroke care should follow the ASA guidelinesi. Any neurological deterioration should be evaluated by urgent CT scan and other evaluations as indicated according to investigator/hospital best practice.
• The total time allowed to achieve patient revascularization is 120 minutes of using the Penumbra System.
• As in all surgical interventions, monitoring of intra-procedural blood loss is recommended so that appropriate management may be instituted.
• Limit the usage of Reperfusion Catheters in arteries larger than the catheter’s outer diameter.
Potential Adverse Events
Possible complications include, but are not limited to, the following:
• allergic reaction and anaphylaxis from contrast media
• acute occlusion
• air embolism
• arteriovenous fistula
• device malfunction
• distal embolization
• false aneurysm formation
• hematoma or hemorrhage at access site
• inability to completely remove thrombus
• intracranial hemorrhage
• kidney damage from contrast media
• neurological deficits including stroke
• vessel spasm, thrombosis, dissection, or perforation

Indication For Use
The Penumbra Pump MAX™ is indicated as a vacuum source for Penumbra Aspiration Systems.
There are no contraindications.
• The canister / tubing is intended for single use only. Do not reuse. Reuse may result in the inability to aspirate.
• Do not block bottom or back air vents. Unit may overheat and shut off or fail to restart if run for extended periods without airflow.
• To avoid risk of electric shock, this equipment must only be connected to a supply mains with protective earth.
• Do not position the pump so that it is difficult to operate the power cord disconnection device.
• Remove and service the pump if liquids or solids have been drawn into the vacuum pump.
• Do not use in the presence of flammable anesthetic mixture with air or nitrous oxide.
• Do not use in oxygen rich environment.
• To prevent fire or shock hazard, use replacement fuses of equal size and rating.
• To prevent fire or shock hazard, use a replacement power cord of equal rating.
• Do not re-infuse blood or fluid from the canister back into the patient.
• Do not use petroleum base compounds, acids, caustics, or chlorinated solvents to clean or lubricate any parts. It will reduce service life of the pump. Use only water-base solvents for cleaning.
• Federal law (USA) restricts this device to sale by or on the order of a physician.
• No modification of this equipment is allowed.
