The TriVascular Ovation Prime™ Abdominal Stent Graft System is an implantable
device made up of three parts: a main body, and two limbs. The main body is
placed in the aorta, and the limbs are then extended from the main body to the
iliac arteries (see image at right).
The main body of the stent graft uses two polymer-filled rings to provide seal
against the wall of the aorta above the aneurysm, while the metal stent
provides fixation of the stent graft to the aorta. The two limbs provide seal
below the aneurysm, containing the flow of blood within the graft and relieving
pressure on the aneurysm.
The catheter used to deliver the stent graft through the femoral arteries is
smaller and more flexible than current commercially available devices. This
should allow for easier passage through the arteries and smaller incisions in
those arteries.
