Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • The treatment vessel is DeNovo
  • Stenotic (\>50%) or occlusive atherosclerotic disease of infrapopliteal artery(s)
  • Reference target vessel diameter between 2-4.0 mm by visual assessment
  • Documented Rutherford Class 4 or 5 symptomatic critical limb ischemia
  • The patient must be \>18 years of age
  • Life-expectancy of more than 12 months
  • The patient has no child bearing potential or negative serum pregnancy test
  • within 7 days of the index procedure
  • The patient must be willing and able to return to the appropriate follow-up times for the duration of the study
  • The patient must provide written patient informed consent that is approved by the ethics committee
  • All inflow lesions successfully (\<30 residual stenosis) treated prior to target lesion treatment during same procedure or according standard of care without unresolved complications
  • At least one angiographically visible target at the ankle for establishment of straight line flow.

You may not qualify if:

  • Patient refusing treatment
  • The target vessel segment diameter is not suitable for available catheter design.
  • Unsuccessfully treated endovascular or bypass( \>30% residual stenosis) proximal ( iliac, superficial femoral, popliteal) inflow limiting arterial/graft stenosis
  • Lesion lies within or adjacent to an aneurysm
  • The patient has a known allergy to heparin, Aspirin or other antiaggregant therapies or a bleeding diatheses or is unable, or unwilling, to tolerate such therapies.
  • The patient has a history of prior life-threatening contrast media reaction.
  • The patient is currently enrolled in another investigational device or drug trial.
  • The patient is currently breast-feeding, pregnant or intends to become pregnant.
  • The patient is unable to provide informed consent
  • The patient has end stage renal disease (currently on any form of dialysis)
  • Known Left Ventricular Ejection Fraction \< 35%
  • The patient has had a myocardial ischemia within 30 days prior to enrollment
  • The patient has had a cardiovascular accident within 90 days prior to enrollment
  • Serum Creatinine \> 150 µmol
  • The patient has a previous bypass in the target limb
  • +1 more criteria
