NCT02921542

Brief Summary

To evaluate vessel lumen quality (gain) and patient outcomes based on treatment with a predetermined laser treatment protocol in patients presenting with varying lesion types or morphologies: homogenous (plaques with a uniform texture-smooth and regular), heterogeneous (plaques with non-uniform texture-smooth and irregular surface), calcific (consisting of calcium) and restenotic (reoccurring narrowing of the vessel following prior treatment) associated with peripheral arterial disease (PAD).

Device: Laser Atherectomy

Interventions

The Turbo-Power is laser atherectomy catheter designed for treatment of de novo or restenotic lesions in native infrainguinal arteries and for the treatment of femoropopliteal artery in-stent restenosis (ISR) in bare nitinol stents with adjunctive percutaneous transluminal angioplasty (PTA).

Sampling MethodNon-Probability Sample
Study Population

Consecutive patients with homogenous, heterogeneous, calcific, or restenotic with above the knee lesions eligible for treatment with laser atherectomy with Turbo-Power (target will be 15 patients enrolled in each category by lesions morphology).

You may qualify if:

  • Patient age at least 18 years.
  • Patient has been informed of the nature of the study, agrees to participate and has signed an approved consent form.
  • Rutherford category 1, 2, 3, or 4
  • Subject Patient presents with clinical evidence of PAD requiring endovascular intervention.
  • Target lesion access must use the femoral approach that will accommodate at least a 7Fr sheath.
  • Angiographic evidence of significant restenosis (≥ 50% by visual estimate).

You may not qualify if:

  • Inability to obtain informed consent.
  • Life expectancy \< 12 months.
  • Pregnancy, suspected pregnancy, or breastfeeding during study period. (Patients of childbearing potential must have negative serum pregnancy test 7 days prior to treatment.
  • Any evidence of hemodynamic instability prior to procedure/randomization
  • Coagulopathy or clotting disorders.
  • Present or suspected systemic infection or osteomyelitis affecting target limb.
  • Contraindication to contrast media or any study-required medication (antiplatelets, anticoagulants, thrombolytic, etc).
