    摘要： A method and system is provided for passing a suture anchor through a soft tissue and into a bone. The method includes the steps of locating a desired anchor receiving site on the bone; passing a locating wire through the soft tissue and into the bone at the anchor receiving site and passing over the locating wire an inner/outer cannula system which includes an inner cannula having a sharp distal tip, and an axial lumen therethrough sized to accommodate the positioning wire and an outer cannula having a distal end, and an axial lumen therethrough sized to accommodate the inner cannula and coaxially receiving the inner cannula, the distal end being tapered wherein to present a gradually increasing profile and wherein the distal tip of the inner cannula extends distally beyond the end of the distal end of the outer cannula. The sharp distal tip of the inner cannula passes through the soft tissue to create an opening therethrough and the tapered distal end of the outer cannula passes through the opening to expand the opening and minimize removal, cutting and disturbance of the tissue as it passes therethrough. The suture anchor passes through the outer cannula and is driven into the bone at the anchor site.

    摘要： Methods and device for extracting and collecting tissue, which can be used for example in tissue engineering and grafting applications, are disclosed. In one embodiment, a device can include an outer tube. A rotatable shaft can be disposed within the outer tube can have a tissue harvesting tip formed on its distal end, the tissue harvesting tip being effective to excise tissue upon rotation thereof A tissue collection device can be included to receive and collected excised tissue, and the tissue collection device can indicate the amount of tissue collected therein. For example, the tissue collection device can include a straining element which collects excised tissue and an indicator by which to assess the amount of collected tissue. In some embodiments, the tissue collection device can translate to indicate the amount of collected tissue. In many cases, devices disclosed herein can include driving mechanisms that are adapted to drive a tissue harvesting tip such that the tip excises soft tissue, but stops when contacting bone (or soon after contacting bone). In some embodiments, the tissue harvesting tip can be effective to excise viable tissue samples, such that the samples can exhibit desirable proportions of viable cells. Further, in some embodiments, the tissue harvesting tips can excise a tissue sample with tissue particles falling in certain size ranges.

    摘要： A stent-graft endoprosthesis is provided. The graft is a non-textile graft made from biocompatible polymers. The biocompatible compatible polymers include poly-para-xylylene polymeric material. The stent is also coated with a poly-para-xylylene polymeric material. The graft is formed by vacuum vapor deposition of diradicals forming the poly-para-xylylene material. The stent is also coated with the poly-para-xylylene material by vacuum vapor deposition.

    摘要： A graft system for intraluminal delivery in a vessel in need of repair comprising a graft, anchoring means, and a strippable sheath around at least part of the graft. A preferred anchoring means is a balloon-expandable stent. Also included in the invention is a method of using the device to treat a body lumen. The strippable sheath is removable by pulling on a drawstring to remove it which permits expansion of the graft. The positioning of the device may then be adjusted prior to stent dilation. A preferred embodiment of the invention includes a bifurcated graft system for intraluminal delivery in an aortic aneurysm comprising a bifurcated graft having a distal region and two legs, an expandable stent disposed in part of the distal region, and a strippable crocheted sheath around the distal region and one of the two legs. The strippable crocheted sheath is removable by untying it to permit expansion of the graft after initial placement within the aneurysm.
