Safety and Efficacy of the SETA LATECBA Stent Graft for EVAR in Subjects With AAA

Prospective, Open-label, Multicenter, Non-randomized Clinical Study to Determine the Safety and Efficacy of SETA LATECBA Stent Graft for Endovascular Repair Therapy (EVAR) in Subjects With Abdominal Aortic Aneurysm (AAA).

This is a Prospective, Open-label, Multicenter, and Non-randomized Clinical Study. The main purpose of this study is to establish the efficacy and safety of a medical device system, SETA LATECBA Stent Graft, intended for the treatment of EVAR of pararenal AAA (patients with complex anatomy, not eligible for other surgical procedure).Other objective is to evaluate the technical performance of the device SETA LATECBA Stent Graft.
