Distal Access Catheters
AXS Catalyst Distal Access Catheter
Indications for Use
The AXS Catalyst Distal Access Catheter as part of the AXS Universal Aspiration System is indicated for use in the revascularization of patients with acute ischemic stroke secondary to intracranial large vessel occlusive disease (in the internal carotid, middle cerebral - M1 and M2 segments, basilar, and vertebral arteries) within 8 hours of symptom onset. Patients who are ineligible for intravenous tissue plasminogen activator (IV t-PA) or who failed IV t-PA are candidates for treatment.

Description
The AXS Catalyst Distal Access Catheter is a sterile, single lumen, variable stiffness catheter designed for use as part of the AXS Universal Aspiration System to restore blood flow in 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. The system includes the AXS Catalyst Distal Access Catheter (intravascular component), AXS Universal Aspiration Tubing, Medela Dominant Flex Pump, and AXS Universal Liner Set. The catheter features a hydrophilic coating, radiopaque marker, and luer hub, and is advanced over a guidewire for thrombus removal via aspiration.
