The APRO 70 Swift Catheter with an aspiration pump and the Alembic Aspiration Tubing 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 thrombolytic drug therapy or who failed thrombolytic drug therapy are candidates for treatment.
The Alembic Aspiration Tubing is intended to connect the APRO 70 Swift Catheter to the aspiration pump.
The APRO 70 Swift Catheter is a single-lumen, braid and coil reinforced catheter. The APRO 70 Swift Catheter is designed to remove thrombus from the vasculature using aspiration. The APRO 70 Swift Catheter targets aspiration from a suction pump directly to the thrombus to remove thrombus from an occluded vessel. The APRO 70 Swift Catheter is introduced through a guide catheter or long femoral sheath and into the intracranial vasculature and guided over a neurovascular guidewire under fluoroscopic visualization to the site of the primary occlusion. The distal shaft has a hydrophilic coating to aid navigation through the vasculature. A radiopaque marker is located at the distal end of the catheter for visualization under fluoroscopy. For the aspiration source, the APRO 70 Swift Catheter is used in conjunction with an aspiration pump with pre-specified performance parameters that is connected using the Alembic Aspiration Tubing, along with a legally marketed canister and accessories kit. The APRO 70 Swift Catheter is available in lengths of 125 cm. 132 cm, and 135 cm and is provided with an introducer sheath.
The Alembic Aspiration Tubing connects the APRO 70 Swift Catheter to the aspiration pump. The flow control valve allows control of the aspiration flow using an ON/OFF switch. It is available in one size.
The provided text describes the acceptance criteria and the study results for the APRO 70 Swift Catheter and Alembic Aspiration Tubing. It is important to note that this document is a 510(k) summary, which focuses on demonstrating substantial equivalence to a legally marketed predicate device through non-clinical performance data, rather than a clinical trial report. Therefore, some of the requested information, particularly regarding clinical studies, human readers, and effect sizes, is not applicable or available in this document.
Here's the breakdown of the information based on your request:
