Description of intervention(s) / exposure
The Route 92 Medical Reperfusion System is intended for use in the revascularization of patients with acute ischemic stroke secondary to intracranial large vessel occlusive disease within the internal carotid and middle cerebral arteries.

An interventional neuroradiologist will administer the Reperfusion System during acute treatment for stroke.

The Route 92 Medical System is a system of products for accessing the neurovasculature and then aspirating clot in ischemic stroke patients. The system is comprised of the Base Camp Sheath System and the Reperfusion Systems. The Reperfusion System is provided in two sizes: 088 and 070. Each Reperfusion System is comprised of a Delivery Catheter and an Aspiration Catheter.

The Base Camp Sheath is placed in the femoral artery and provides access to the carotid artery. The 088 Reperfusion System may be placed through the Base Camp Sheath. The 070 Reperfusion System may then be placed through the 088 Aspiration Catheter to form a “telescoping” family of products. Once an Aspiration Catheter has gained access to the neurovasculature, the stroke-causing embolus may be aspirated.

The approximate duration of the revascularization procedure is expected to be less than 1 hour.
