摘要:
A segmented balloon expandable stent graft includes a graft material and a plurality of cylindrical stent elements coupled to the graft material. The plurality of cylindrical stent elements are plastically deformable when expanded from a radially compressed configuration to a radially expanded configuration. The plurality of cylindrical stent elements includes a first end stent element, a second end stent element, and a plurality of middle stent elements. The first and second end stent elements are independent of the plurality of middle stent elements. The first and second end stent elements are more resistant to radial expansion than the plurality of middle stent elements such that the plurality of middle stent elements plastically deform from the radially compressed configuration to the radially expanded configuration when inflated by a balloon prior the first and second end stent elements.
