MINIMALLY INVASIVE TREATMENT SYSTEM FOR AORTIC ANEURYSMS

摘要

An endoluminal prosthesis (10) comprises a radially expandable tubular segment (12) having a first end (32), a second end (34), a lumen interconnecting the first end (32) and the second end (34). A connection portion (52) defines an opening in the tubular segment (12) in fluid communication with the lumen. The connection portion (52) includes a converging portion (54), an annular diverging portion (56) and an annular neck portion (58) interconnecting the converging portion (52) and the diverging portion (56).
