Abstract:
1. A stent graft comprising: one or more stent segments, each stent segment comprising a plurality of struts connected in a substantially zigzag pattern, wherein one or more struts in each stent segment comprises a reduced profile section, each of the stent segments having a gap therebetween; a biocompatible graft material affixed to the one or more stent segments, the graft material having indented sections in the regions of the gaps between the stent segments; and at least one attachment device for securing the biocompatible graft material to the one or more stent segments, the at least one attachment device comprising a deformable, partially tubular band having a slotted opening for accepting a portion of a strut and a portion of the biocompatible graft material, the deformable, partially tubular band having a substantially linear initial shape and being deformable to substantially surround and conform to the shape of the strut at the reduced profile section with a substantially rectangular final shape, thereby slidably engaging the graft material to the strut and graft material without puncturing either the graft material or the strut, the deformable, partially tubular band being configured to allow relative movement between the biocompatible graft material and the strut and configured to slidably secure the biocompatible graft material to the strut of the one or more stent segments, the at least one attachment device comprises a metallic material.
