Stent for Peripheral Arterial Disease:

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
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.
