    摘要: The present embodiments provide an endoluminal prosthesis, such as a stent-graft, having a relatively low delivery profile. In one embodiment, the prosthesis comprises a membrane, and at least one stent having contracted and expanded states, where the stent is coupled to the membrane and maintains patency in the expanded state. The prosthesis further may comprise selectively oriented axial and/or circumferential fibers arranged at predetermined locations along the length and circumference of the prosthesis. An increased population density of the circumferential and/or axial fibers may be provided in areas in which the at least one stent portion is attached to the membrane, or in areas of higher physiological loads imposed upon the endoluminal prosthesis. Selectively orienting axial fibers and circumferential fibers at predetermined locations along the length and circumference of the prosthesis, but not continuously along the entire prosthesis, significantly reduces delivery profile due to the reduction in graft material.

    摘要: A variable curvature stent limb is disclosed herein. A stent derived from a plurality of these variable curvature stent limbs may be highly compressible, such that it is compatible with a low-profile delivery device. This stent may be useful over a wider range of body vessel diameters and may possess a greater fatigue life, since this stent may provide a more controlled constant radial force.

    摘要: The present invention relates to methods of treating tissue of the human body, specially, methods of promoting cell proliferation and ingrowth around implantable medical devices. The methods include inserting an apparatus comprising asperities adapted to injure native tissue at a desired anchoring location, injuring the native tissue at the desired anchoring location with the apparatus to initiate an injury response in the native tissue to thereby promote cell proliferation and ingrowth; and implanting the medical device at the treatment location.
