Warnings
• The INDIGO Aspiration System should only be used by physicians who have received appropriate training in interventional techniques.
• Do not advance, retract or use any component of the INDIGO 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 INDIGO Aspiration System with a pump other than the Penumbra Aspiration Pump.
• Placing guidewire too distal in the pulmonary vasculature or excessive manipulation of aspiration/guiding catheter in the smaller, peripheral, and segmental pulmonary artery branches can result in vessel perforation.
Precautions
• The device is intended for single use only. Do not resterilize or reuse.
• 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 INDIGO Aspiration System in conjunction with fluoroscopic visualization.
• Maintain a constant infusion of appropriate flush solution.
• When performing aspiration, ensure that the INDIGO Aspiration Tubing is open for only the minimum time needed to remove thrombus. Excessive aspiration or failure to close the INDIGO Aspiration Tubing when aspiration is complete is not recommended.
• Hemoglobin and hematorcrit levels should be monitored in patients with >700 mL blood loss from the clot aspiration procedure.
• The INDIGO SEPARATOR is not intended for use as a guidewire. If repositioning of the INDIGO Aspiration Catheter is necessary during the revascularization procedure, such repositioning should be performed over an appropriate guidewire using standard catheter and guidewire techniques.
• Do not use automated high-pressure contrast injection equipment with the INDIGO Aspiration Catheter because it may damage the device.

• The removal of fibrous, adherent or calcified material (e.g. chronic clot, atherosclerotic plaque)
• The cerebral vasculature
Warnings
• The Indigo Aspiration System should only be used by physicians who have received appropriate training in interventional techniques.
• Do not advance, retract or use any component of the Indigo Aspiration 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 Indigo Aspiration System with a pump other than the Penumbra Aspiration Pump.
Precautions
• The safety and effectiveness of this device for use in the treatment of ST-Elevation Myocardial Infarction (STEMI) has not been established. Complications from the use of this device in this manner could lead to death, permanent impairment, and/or the need for emergency medical intervention.
• 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 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 Indigo Aspiration System in conjunction with fluoroscopic visualization.
• Maintain a constant infusion of appropriate flush solution.
• When performing aspiration, ensure that the Indigo Aspiration Tubing valve is open for only the minimum time needed to remove thrombus. Excessive aspiration or failure to close the Indigo Aspiration Tubing valve when aspiration is complete is not recommended.
• The Indigo Separator 4 is not intended for use as a guidewire. If repositioning of the Indigo CAT RX Aspiration Catheter is necessary during the revascularization procedure, such repositioning should be performed over an appropriate guidewire using standard guidewire techniques.
• Do not use Indigo Separator 4 to macerate or retrieve thrombus distal to the catheter tip. Indigo Separator 4 is intended to be used with Indigo CAT RX Aspiration Catheter to clear the distal end of the catheter lumen should it be blocked with thrombus.
• Do not use automated high-pressure contrast injection equipment with the Indigo CAT RX Aspiration Catheter because it may damage the device.
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; death; device malfunction; distal embolization; emboli; false aneurysm formation; hematoma or hemorrhage at access site; inability to completely remove thrombus; infection; hemorrhage; ischemia; kidney damage from contrast media; neurological deficits including stroke; vessel spasm, thrombosis, dissection, or perforation; intimal disruption; myocardial infarction; emergent surgery; fibrillation; hypotension; respiratory failure; peripheral thromboembolic events.
Penumbra ENGINE – Indication For Use
