The Ovation Stent Graft System is a new, trimodular endoprosthesis for the treatment of Abdominal Aortic Aneurysms. A long nitinol stent with anchors serves the suprarenal fixation whereas inflatable rings in the main body achieve sealing. This dissociation precludes the presence of a nitinol skeleton in the endograft, thus avoiding ...

The popliteal artery may well be the most challenging of all infra-inguinal vessels to treat. Not only is it anatomically unique but it's also exposed to some of the most brutal forces seen in the lower limb, during normal knee flexion. Management may be challenging and with few randomized trials ...
