10. German Clinical Ovation TM Trial  Objective: 2-year safety and performance  Primary Endpoint:  SAE within 30 days of the procedure  Secondary Endpoints:  Treatment success defined as:  Deployment  Freedom From: Type I, III & IV endoleak, migration, AAA enlargement, rupture, and conversion  Follow-up: 1 month, 6 months, 2 years and annually to 5 years

11. Inclusion & Exclusion Criteria  AAA ≥ 5.0 cm in diameter or ≤ 5.0 cm in diameter if:  Ø increased ≥ 5 mm in 6 months  Ø is 1.5 times normal aortic diameter  Proximal neck:  ≥ 7 mm in length  16 to 30 mm in diameter (ID)  ≤ 45° angle (neck < 10 mm)  ≤ 60° angle (neck ≥ 10 mm)  Distal Iliac landing zone of:  ≥ 10 mm in length  8 to 20 mm diameter (ID)  Overall length from renal to hypogastric artery ≥ 130 mm  Adequate iliac/femoral access compatible with the delivery systems

14. Summary  The Ovation Abdominal System is a novel technology that optimizes the two most important requirements for EVAR, fixation and seal.  The clinical trail has yielded excellent short-term results across a broad cohort of patients.  The 14F OD system offers the lowest profile of any commercially available device, and is designed to expand the patient population suitable for endovascular aortic repair (EVAR) by addressing a wider range of diseased anatomies.
