    摘要： The present embodiments provide an introducer sheath having a braided member and methods of manufacture. The introducer sheath comprises an inner tube, a braided member disposed over at least a portion of the inner tube, and an outer tube disposed over the inner tube and the braided member. In one embodiment, the braided member comprises a plurality of intersecting first and second wire segments at least partially covered with a coating. At least a portion of the first and second wire segments are bonded together at one or more intersections, for example, by melting the coating, to reduce movement of at least one of the first and second wire segments with respect to one another. Optionally, a coiled member having a plurality of turns may be disposed over a portion of the braided member and the inner tube.

    摘要： A stent-graft fabricated from a thin-walled, high strength material provides for a more durable and lower profile endoprosthesis. The stent-graft comprises one or more stent segments covered with a fabric formed by the weaving, knitting or braiding of a biocompatible, high tensile strength, abrasion resistant, highly durable yarn such as ultra high molecular weight polyethylene. The one or more stent segments may be balloon expandable or self-expanding. The fabric may be attached to the stent segments utilizing any number of known materials and techniques. The fabric may be attached to the stent segments utilizing an attachment device that secures the fabric to a strut of the stent segment by sandwiching the fabric between itself and the stent strut.

    摘要： A valve assembly includes a valve collar, a rotatable valve control member, and a flexible valve member disposed therebetween. The valve control member and the valve collar are aligned to define an elongated passageway, and the flexible valve member is disposed along the passageway. The valve collar is structured such that at least a portion thereof is capable of radial flexure upon engagement with a mechanism on the rotatable valve control member. One end of the valve member is secured to the valve collar, and the other end is secured to the rotatable valve control member. Upon rotation of the rotatable valve control member relative to the valve collar, the mechanism of the rotatable valve control member engages the valve collar portion in a manner such that the valve collar portion flexes in a radial direction and a tactile sensation is produced thereby, and the flexible valve member constricts from an open position to a position wherein the flexible valve member opening is at least partially closed to passage of fluid therethrough.

    摘要： The present invention relates to a medical device delivery system. The delivery system includes an introducer sheath having an elongated tubular member having a passageway extending generally longitudinally therethrough. The passageway is defined by an inner surface of the tubular member and is configured to receive a medical device moveably disposed therein, where at least a portion of the inner surface of the inner tube comprises a non-uniform surface configured to reduce surface contact between the inner surface and the medical device. The delivery system includes an inner catheter configured to slidably extend throughout the passageway of the introducer sheath. A prosthesis is disposed within a distal portion of the introducer sheath, where the prosthesis is supported within the introducer sheath by the inner catheter.
