Carotid Stent Trial to Evaluate the Safety and Efficacy of the Roadsaver™ Stent Used in Conjunction with the Nanoparasol® Embolic Protection System for Patients at Increased Risk for Adverse Events from Carotid Endarterectomy.
To evaluate the safety and effectiveness of MicroVention, Inc. Roadsaver™ Carotid Stent System used in conjunction with the Nanoparasol® embolic protection system for the treatment
Devices Used in Trial:
- The Roadsaver™ system consists of self-expanding nickel titanium (Nitinol) stent implant and a rapid exchange (RX) delivery catheter. The self-expanding implant is designed to expand to a pre-determined diameter when deployed by the delivery catheter. The implant is produced with various outer diameters ranging from 5-10 mm and with lengths of 20-40 mm. Upon exiting the delivery catheter at the target lesion, the implant expands to conform to the vessel lumen diameter.
- The Nanoparasol® embolic protection system is designed to capture and remove dislodged debris during a carotid interventional procedure. When the interventional procedure is complete, a retrieval catheter is advanced over the guidewire to close and capture the filter before the entire assembly is withdrawn from the patient.
- Patient is between >21 and ≤80 years of age.
- Patient is willing and capable of complying with all study protocol requirements, including specified follow-up period and can be contacted by telephone.
- Patient or authorized legal representative is willing to provide written informed consent prior to enrollment in study.
- Patient should have been diagnosed with carotid artery stenosis and be considered a high operative risk for carotid endarterectomy.
- Patient is either:
- Symptomatic with carotid stenosis ≥50% as determined by angiography using NASCET methodology. Symptomatic is defined as amaurosis fugax ipsilateral to the carotid lesion; TIA or non-disabling stroke within 180 days of the procedure within the hemisphere supplied by the target vessel; or
- Asymptomatic with carotid stenosis ≥80% as determined by angiography using NASCET methodology.
- Patient has a target lesion located at the carotid bifurcation and/or proximal ICA.
- Patient has a single de novo or restenotic (post CEA) target lesion or severe tandem lesions close enough that can be covered by a single Roadsaver™ stent.
- Patients having a vessel with reference diameters between 3.0 mm and 9.0 mm at the target lesion.
