Abstract
A stent includes a main body having proximal and distal ends, and at least one conformance strut coupled to the proximal end of the main body. A portion of the at least one conformance strut extends proximal to a proximal end of a graft material in a compressed delivery configuration, and further is aligned inside the proximal end of the graft material in an expanded deployed configuration. In the deployed configuration, the proximal conformance strut may at least partially encircle the graft material just distal to the proximal end of the graft material, which may reduce the likelihood of infolding at the proximal edge of the graft material and potential endoleaks.
