Endoprosthetic device comprising a support channel capapble of receiving a branch endoprosthetic device

Abstract

The present disclosure includes an endoprosthesis comprising a tube or substantially tubular lumen. The tube can comprise a first end and a second end, and a side wall can extend between the first and second ends. The side wall can be fenestrated by a side opening or fenestrated portion. The endoprosthetic device can further comprise a patch or support wall coupled to an inner surface of the side wall. The patch can overlap the fenestration. Further, the patch can have a first open edge and/or a second open edge, both of which can open to receive a branch endoprosthetic device. The patch can be movable between a closed configuration adjacent to the inner surface of the side wall and an open configuration spaced apart from the inner surface of the side wall. The open configuration can define a support channel that receives the branch endoprosthetic device.
