STENT GRAFT, ASSEMBLY AND ENDOVASCULAR AORTIC REPAIR METHODS

摘要

A branched stent graft system includes an elongate main stent graft extending along a central longitudinal axis. The main stent graft is configured for deployment in a main vessel and has a cell zone extending along the axis and has a wire mesh and a puncturable wall divided by the wire mesh into a plurality of cells, which includes at least one cell defining a through hole in the wall of the cell. The system also includes a branch stent graft having a tubular body extending longitudinally from a proximal end to a distal end. The branch stent has a flange extending from the proximal end and the flange has an outer diameter that is larger than a diameter of the through hole. The branch stent extends through the hole and is fluidly sealed at the flange to an inner surface of the cell zone surrounding the through hole.
