LIFESTENT FOR PERIPHERAL ARTERIAL DISEASE Lifestent by Bard for upper leg and knee. The LIFESTENT Vascular Stent is the only stent approved by the U.S. Food and Drug Administration and commercially available for use in the SFA and proximal popliteal artery, which are both arteries above the knee. The narrowing of these arteries is responsible for the symptoms associated with peripheral artery disease (P.A.D.). SFA= Superficial femoral artery is a large artery in the muscles of the thigh. The popliteal artery is defined as the extension of the "superficial" femoral artery after passing through the adductor canal and adductor hiatus above the knee. If not treated, P.A.D. can limit the ability to walk and exercise, as well as place patients at risk for limb loss. P.A.D. patients also have a greater chance of heart attack, stroke and death. In a recent randomized, controlled, multi-center trial, 206 patients who required treatment for lesions up to 15cm received either PTA (percutaneous transluminal angioplasty) alone or PTA and a LIFESTENT Vascular Stent. This trial provided compelling evidence that the self-expanding nitinol stent can keep the arteries open and reduce the need for additional procedures better than balloon angioplasty alone.
