Safety and Effectiveness of Jetstream Atherectomy System (J-SUPREME II)

Not Applicable

Completed

• Conditions: Peripheral Arterial Disease
• Interventions: Device: Jetstream Atherectomy System

• Registration Number: NCT03847233
• Lead Sponsor: Boston Scientific Corporation

Brief Summary

The purpose of this study is to evaluate the safety and effectiveness of the Jetstream Atherectomy System for the treatment of Japanese patients with symptomatic occlusive atherosclerotic lesions in native superficial femoral artery (SFA) and/ or proximal popliteal arteries (PPA).

Detailed Description

A prospective, multicenter, single-arm trial evaluating the safety and efficacy of the Jetstream Atherectomy System in the treatment of symptomatic occlusive atherosclerotic lesions ≤150 mm in length located in the femoropopliteal arteries in subjects with symptoms classified as Rutherford categories 2-4.
