Patent number: 9622887Abstract: A stent graft has a cylindrical wall, an internal lumen within the cylindrical wall and a fenestration in the wall. The fenestration is closed off by a valve arrangement to prevent the flow of liquids from within the internal lumen to outside of the wall. The valve arrangement is a tube of graft material which can be closed off by pressure on its outside surface. The end of the tube remote from the fenestration can be held shut by having its periphery fastened to a flattened resilient ring. Fluid pressure on the tube of graft material causes the tube to close off to prevent fluid flow therethrough and by resilient deflection of the resilient ring the end of the tube of graft material can be opened to enable the passing of a medical device therethrough.Type: GrantFiled: November 3, 2014Date of Patent: April 18, 2017Assignee: Cook Medical Technologies LLCInventors: Werner D.
