About this study

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.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

  • Pregnant or nursing a child.
  • Contraindication, intolerance, or allergy to contrast media that, in the opinion of the investigator, cannot be adequately pre-medicated.
  • Myocardial infarction within 60 days prior to index procedure.
  • History of severe trauma and/or sepsis within 60 days prior to index procedure.
  • Cerebrovascular accident (CVA) or Transient Ischemic Attack (TIA) within 60 days prior to index procedure.
  • Evidence of intracranial or gastrointestinal bleeding or intracranial aneurysm within 90 days prior to index procedure.
  • Abnormal electrocardiogram or blood test results and/or any other factor that would increase risk by participating in the study in the opinion of the investigator.
  • Target lesion not crossed with guidewire or extraluminal guidewire crossing (even if in short segments only).
  • Additional lesion that is located >3cm away from the target lesion
  • Treatment plan of the target lesion includes laser, brachytherapy, or atherectomy other than the Rotarex®S Catheter.
  • Patient is currently participating in another investigational drug or device study that has not reached the primary endpoint.
  • Patients contraindicated for antiplatelet therapy, anticoagulants or thrombolytics.
  • Patients with uncorrected bleeding disorders.
  • Thrombophlebitis or deep vein thrombosis within the past 30 days.

Treatment and study plan

Atherectomy/Thrombectomy

Device

Percutaneous transluminal removal of thrombotic, thromboembolic and atherothrombotic material from fresh, subacute and chronic occlusions of blood vessels in native blood vessels or vessels fitted with stents, stent grafts or native or artificial bypasses.
