Treo® Aorto Uni Iliac (AUI) is a low-profile 19Fr endoprosthesis, composed of an AUI body (a single branch) so as to maintain the blood flow to the right or left iliac artery, a distal extension branch and an occluder that is placed in the iliac artery on the other side to prevent the retrograde perfusion of the aneurysmatic sac. The framework of these three components is Dacron with self-expandable nitinol stents arranged in a Z pattern, and the AUI body also has a uncovered proximal stent. Treo® AUI is indicated for the treatment of abdominal aneurysms where bifurcated bodies cannot be used.
Unlike other endoprosthesis it has a double active fixation with suprarenal and infra-renal hooks that only come into action when the aorta presents infra-renal angulation
- AUI body available of 100 mm and diameters of 20 – 36 mm.
- Lengths of 31 – 33 – 35 mm.
- Diameters of 8 – 10 – 12 – 14 – 17 – 20 – 24 mm.
