This is an interventional treatment trial for Restenosis focused on measuring Restenosis, aspiration, in-stent restenosis, atherectomy, superficial femoral artery, popliteal artery Read More

Inclusion Criteria:

1. Subject is 18 years of age or older.
2. Subject presents with clinical evidence of peripheral arterial disease with ISR in the femoropopliteal segment (includes common femoral, superficial femoral and popliteal)
3. Subject presents with a Rutherford Classification of 1-5 and has symptoms of rest limb pain, ulcerations or claudication.
4. Target lesion(s) must be viewed angiographically and have ≥50% stenosis.
5. The atherectomy wire must be placed entirely across all lesions to be treated with no visible evidence of clear or suspected subintimal/substent wire passage.
6. The main target vessel reference diameter must be at least 5 mm.
7. One patent distal run-off vessel with brisk flow is required.
8. Patient is an acceptable candidate for percutaneous intervention using the Jetstream NAVITUS System in accordance with its labeled instructions for use.
9. Patient has signed approved informed consent.
10. Patient is willing to comply with the follow-up evaluations at specified times.

Exclusion Criteria:

1. Subject is unable to understand the study or has a history of non-compliance with medical advice.
2. Subject is unwilling or unable to sign the Informed Consent Form (ICF).
3. Subject is currently enrolled in another clinical investigational study that might clinically interfere with the current study endpoints (e.g., limit use of study-recommended medications, etc.).
4. Subject is pregnant or planning to become pregnant within the study period.
5. Subject has a known sensitivity to contrast media and the sensitivity cannot be adequately pre-medicated for.
6. Subject is diagnosed with chronic renal failure or has a creatinine level > 2.5 mg/dl and is not on chronic dialysis.
7. Subject has a known allergy to heparin, ASA, Plavix.
8. Subject has a history of bleeding disorders or platelet count < 80,000 cells/ml.
9. Subject experiences ongoing cardiac problems (e.g., cardiac arrhythmias, congestive heart failure exacerbation, myocardial infarction, etc.) that, per the investigator, would not make the subject an ideal candidate for study procedures.
10. Subject has a CVA or TIA within 4 weeks prior to JetStream procedure.
11. Subject has an anticipated life span of less than 6 months.
12. Subject is suspected of having an active systemic infection.
13. Subject per the investigator's medical judgment must be excluded from the study.
14. Limited vascular access that precludes safe advancement of the Jetstream NAVITUS System to the target lesion(s).
15. Patient has evidence of intracranial or gastrointestinal bleeding within the past 3 months.
16. Patient has had severe trauma, fracture, major surgery or biopsy of a parenchymal organ within the past 14 days.
17. Patient has any planned surgical intervention or endovascular procedure within 15 days after the index procedure.
18. Use of another debulking device during the index procedure prior to the Jetstream NAVITUS System.

19. Use of another debulking device after the Jetstream NAVITUS system.
