Zoom 7X Catheter; Zoom Aspiration Tubing; Zoom POD Aspiration Tubing
The Zoom 7X Catheter, with the Zoom Aspiration Tubing or Zoom POD Aspiration Tubing, and the Zoom Aspiration Pump (or equivalent vacuum pump), is 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 last known well.
Patients who are ineligible for intravenous thrombolytic drug therapy or who have not responded to thrombolytic drug therapy are candidates for treatment.
The Zoom Aspiration Tubing and the Zoom POD Aspiration Tubing are intended to connect the Zoom (7X, 71, 55, 45, 35) Catheter and the TracStar LDP Large Distal Platform, the Zoom 88 Large Distal Platform, or the Zoom 88 Large Distal Platform Support to the Zoom Canister of the Zoom Aspiration Pump (or equivalent vacuum pump) and to allow the user to control the fluid flow.
The Zoom™ 7X Catheter is a single lumen, braid and coil reinforced, variable stiffness catheter that facilitates removal of thrombus/clot from the neurovasculature when connected to a vacuum source, such as the Zoom Aspiration Pump, using the Zoom Aspiration Tubing or the Zoom POD Aspiration Tubing.
The Zoom 7X Catheter is comprised of a hollow cylindrical tube which is bonded to a standard luer fitting. The wall of the tube is constructed using a combination of metal coils/braids and medical grade polymers.
The distal section of the Zoom 7X Catheter has a hydrophilic coating to enhance tracking through the vasculature. The beveled distal tip allows for atraumatic tracking past vessel branches during insertion. A radiopaque marker provides the user with visual confirmation of the distal tip location under fluoroscopy.
The Zoom 7X Catheter is packaged with an accessory Rotating Hemostasis Valve (RHV). The RHV is intended to be attached to the proximal hub of the catheter and used to control hemostasis during use with other devices. The Zoom 7X Catheter is also packaged with two (2) introducer sheath accessories. The introducer is intended to assist with insertion of the Zoom 7X Catheter into the RHV or the guide catheter.
The Zoom Aspiration Tubing and the Zoom POD Aspiration Tubing are comprised of a hollow cylindrical tube which is bonded to a standard luer fitting that connects to the Zoom 7X Catheter and a slip fit connector that connects to the canister on the aspiration pump. The Zoom Aspiration Tubing is made of common medical grade polymers.
