The Bifurcated PowerLink System is intended to provide a permanent alternative conduit for
blood flow within a patient's abdominal vascular system, which excludes the aneurysmal sac
from blood flow and pressure.
An arterial anuerysm is a permanent, localized dilatation of an artery with an increase in
diameter ≥ 50% larger than the normal artery. Although any artery may develop an aneurysm,
they are most commonly seen in the abdominal aorta, the thoracic aorta, the popliteal artery
and the common iliac artery.
The use of intravascular stents and endoluminal grafts to exclude natural arterial aneurysms
or treat occlusive vascular lesions has been evaluated in a number of preclinical studies.
Endovascular stent graft implantation obviates the need for abdominal surgery by using the
peripheral arteries as a route to the aneurysm, and stents provide a means of graft
attachment other than sutures. The goal of endoluminal grafting is the same as that of
conventional repair and allows insertion of a resilient conduit between the ends of the
aneurysm to exclude it from the circulation and prevent rupture of the aneurysm.
This is a Phase 2 Clinical Study of the Bifurcated PowerLink System (Endoluminal Graft) for
the treatment of abdominal infrarenal aorto-iliac aneurysmal disease (AAA). Diagnostic
imaging methods such as Spiral CT Scans, angiography, ultrasound and fluoroscopy imaging
will be used to choose the sites for placement of the device and to assure precise
The Delivery Catheter allows endovascular placement of the Device (endoluminal graft) via
either retrograde (femoral or iliac arteries) or antegrade (brachial arteries) approaches.
The Endoluminal Graft (ELG) is a self-expanding metal alloy stent cage, which is covered on
the outside by a thin walled ePTPE graft material. The graft material is fully supported
throughout the entire ELG length. The ELG is also available in a bifurcated configuration.
The bifurcated delivery catheter is available in various diameters and working lengths. The
catheter consists of an introducer sheath with homeostatic vavle and an inner shaft. The
inner shaft is an obturator with a tapered tip connected to a rear obturator by means of a
hypotube. The main body of the ELG is compressed around the hypotube then loaded into the
Delivery Catheter. The contralateral and ipsilateral limbs of the ELG are compressed in
their respective limb covers and loaded into the Delivery Catheter. The inner shaft
accommodates a standard .035 inch guidewire.
The concurrent surgical control and test patients' participation in the Study will include
enrollment, the Investigational Device procedure or surgical repair and follow-up period.
Patient data will be collected during: pre-operative, operative and post-operative follow-up
at discharge and at 1 month. Long term follow-up for both the concurrent surgical controls
and test patients will continue for 6 and 12 months to support a PMA. Extended follow-up
may be required until the Investigational Device is approved under a PMA, or up to 5 years
follow-up under Post Market Surveillance requirements.
