Abstract
An aneurysmal repair system that utilizes a modified apex and delivery device is designed for accurate endoprosthesis delivery and deployment. The modified apex utilizes segments that overlap and hold one another down as well as the fixation barbs attached thereto. The delivery device holds or secures at least one section of the apex and may be easily released by retraction of a hold down member.
