Nellix is a highly differentiated technology platform that is designed to uniquely and completely fill and seal the aortic aneurysm sac, with the aim of preventing device migration and endoleak, and therefore potentially reducing the need for secondary procedures. Clinical investigations are intended to demonstrate the applicability of Nellix to a broad range of AAA anatomies, including those that are outside the approved indications of existing devices. The following are among the anatomical requirements for patients to be enrolled in the clinical investigations:

• Non-aneurysmal aortic neck length of ≥ 5mm
• Non-aneurysmal aortic neck diameter of 16 to 36mm
• Maximum aortic blood flow lumen diameter of ≤ 60mm
• Common iliac artery diameter of 8 to 35mm
