EXPERIMENTALInterventions
A rotating, aspirating, expandable catheter system for active removal of atherosclerotic debris and thrombus in the SFA and/or PPA
Eligibility Criteria
You may qualify if:
- Chronic, symptomatic lower limb ischemia defined as Rutherford categories 2-4
- Stenotic, restenotic or occlusive lesion(s) located in the native SFA and/or PPA of which meet the following criteria:
- Severely calcified lesions with degree of stenosis ≥70%
- Vessel diameter ≥3.0 mm and ≤6.0 mm
- Total lesion length (or series of lesions) ≤150 mm
You may not qualify if:
- Target lesion/vessel with in-stent restenosis
- History of major amputation in the target limb
- Subject has a history of coagulopathy or hypercoagulable bleeding disorder
- Subject with untreatable hemorrhagic disease or platelet count \<80,000mm3 or \>600,000mm3 as baseline assessment.
- History of myocardial infarction, or stroke/cerebrovascular accident (CVA) within 6 months prior to study enrollment
- Unstable angina pectoris at the time of the enrollment
- Septicemia at the time of enrollment
- Presence of other hemodynamically significant outflow lesions in the target limb requiring a planned surgical intervention or endovascular procedure within 30 days after the index procedure
- Presence of aneurysm in the target vessel
- Acute ischemia and/or acute thrombosis of the SFA/PPA prior to the index procedure
- Perforated vessel as evidenced by extravasation of contrast media prior to the index procedure
