Riptide™ Aspiration System

Indications for use

The Riptide™ Aspiration 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, 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 fail IV t-PA therapy are candidates for treatment. 

Description

The Riptide™ Aspiration System is comprised of the following devices:

  • React™ 68 Catheter REACT-68
  • React™ 71 Catheter REACT-71
  • Riptide™ Large Bore Aspiration Tubing MAT-110-110
  • Riptide™ Aspiration Pump MAP-1000EU
  • Riptide™ Collection Canister with Intermediate Tubing MAC-1200

The Riptide™ Aspiration System is designed to remove occlusive thrombus from the cerebral vasculature using continuous aspiration. The catheter shaft has a hydrophilic coating that spans the distal 40 cm to reduce friction during use. The catheter acts as a conduit for providing direct aspiration to the occlusion site generated by the Riptide™ Aspiration Pump. The catheter is introduced through a guide catheter or sheath and into the intracranial vasculature and guided over a neurovascular guidewire and/or microcatheter to the site of the primary occlusion. The catheter is connected to the Riptide™ Aspiration Pump through the aspiration tubing. The Intermediate Tubing connects the Riptide™ Collection Canister to the Riptide™ Aspiration Pump. The Riptide™ Aspiration System in this configuration may be used to aspirate thrombus from the occluded vessel.

Note: The catheter and aspiration tubing are Applied Parts.

Precautions

  • The catheter and the aspiration tubing are supplied sterile and are intended for single use only. Do not resterilize or re-use. Resterilization and/or re-use may result in ineffective catheter coating lubrication, which may result in high friction and the inability to access the target neuro vasculature location. 
  • Use the catheter, aspiration tubing, and Riptide™ Collection Canister with Intermediate Tubing prior to the “Use-by date”.
  • The Riptide™ Aspiration Pump and Riptide™ Collection Canister with Intermediate Tubing are supplied non-sterile and are intended for use outside of the sterile field only.
  • The Riptide™ Collection Canister with Intermediate Tubing is intended for single use only. Dispose in accordance with standard biologic waste disposal procedures.
  • Do not use kinked or damaged devices. Do not use open or damaged packages.
  • Inspect the catheter before use to verify that its size and condition are suitable for the specific procedure.
  • Use the catheter under fluoroscopic guidance to confirm placement of the catheter proximal to the thrombus prior to applying aspiration.
  • Maintain a constant infusion of appropriate flush solution.
  • When performing aspiration, ensure that the aspiration tubing flow switch is in the open position for only the minimum time needed to remove thrombus.
  • The recommended continuous duration of aspiration is a maximum of 90 seconds.
  • If repositioning of the catheter is necessary during the revascularization procedure, such reposition should be performed over an appropriate neurovascular guidewire and/or microcatheter using standard techniques.
  • Do not use automated high-pressure contrast injection equipment with the catheter because it may damage the device.
  • Medical management and post stroke care should follow AHA/ASA guidelines and institutional protocols.
  • As in all surgical interventions, monitoring of intra-procedural blood loss is recommended so that appropriate management may be instituted.
  • Possible malfunctions of the Riptide™ Aspiration System include, but are not limited to, issues associated with vacuum for the aspiration tubing, Riptide™ Aspiration Pump, and Riptide™ Collection Canister with Intermediate Tubing that may lead to decreased therapeutic response during mechanical thrombectomy.
  • Operators should take all necessary precautions to limit X-radiation doses to patients and themselves by using sufficient shielding, reducing fluoroscopy times, and modifying X-ray technical factors where possible.
