THORACIC AORTIC ANEURYSM STENT GRAFT

摘要

PPROBLEM TO BE SOLVED: To solve the problem that for an aneurysm that develops in the thoracic arch of the aorta, stent grafts are needed that are deployable to extend along the substantial curvature of the arch without occluding the main branch vessels joined to the aorta along the arch's curve, all of which may be involved in and compromised by the aneurysm. PSOLUTION: A thoracic stent graft (20) has a tubular biocompatible graft material body (22) with a lumen therethrough with a proximal end (26) and a distal end (27). A sealing stent (28) is attached to the proximal end of the tubular graft material body (22). An anchoring device may be a "barb" (30) affixed to the sealing stent (28). A distal attachment stent (34) with "barbs" (30) can be affixed to and extend from the distal end (27) of the tubular graft material body (22). Intermediate stents (24) are provided along the length of the tubular graft material body (22). The thoracic stent graft can be in one or two portions. PCOPYRIGHT: (C)2011,JPO&INPIT
