Brief Summary

Post-Market Clinical Follow Up of the Rotarex®S Catheter

Detailed Description

A prospective, multi-center, non-randomized, multiple cohorts, observational, post market clinical follow-up study of the Rotarex®S Catheter to evaluate the safety, technical performance and medical efficacy of the Rotarex®S Catheter as a stand-alone and adjunctive therapy for the treatment of acute, subacute and chronic occlusions and sub-occlusions of arteries outside the cardiopulmonary, coronary and cerebral circulations, in accordance with Rotarex®S Catheter intended use.
