Stent Graft With Internal Tube

摘要

A stent graft ( 1 ) with an internal tube ( 15 ) extending from the fenestration ( 11 ) within and towards an end of the tubular body ( 3 ) of the stent graft. An end of the tube remote from the fenestration is flared into a funnel or elliptical shape ( 17 ) to facilitate access into the internal tube from a main lumen of the stent graft. The flared portion is fastened ( 19 ) to the wall of the stent graft. The flared portion is held open with a resilient wire ring ( 21 ).
