    摘要： Partially encapsulated stents are made using gaps cut into ePTFE covering material. Ring stents are placed over an inner ePTFE tube (e.g., supported on a mandrel) and are covered by a “lacey” graft sleeve, which is constructed by cutting apertures into an ePTFE tube so that a series of circumferential and longitudinal strips is created. This “lacey” sleeve is then laminated to the inner ePTFE tube to capture the stents. By selecting the size and position of the apertures in the ePTFE covering, it is possible to leave critical parts of the stent unencapsulated to facilitate flexibility and expansion. Alternatively, the gaps can consist of slits cut into the ePTFE covering material. These slits can be cut in any direction including longitudinally, radially, or diagonally. In addition, the slits can be spaced at varying intervals around the covering material to maximize flexibility and expandability. Although a single stent can be used, these approaches lend themselves to use of a plurality of individual ring stents spaced apart along the inner ePTFE tube.

    摘要： An elongated shaft is sized and configured to establish an access path to bone having an interior volume occupied, at least in part, by cancellous bone. The elongated shaft includes a generally closed distal end portion and a side opening spaced from the closed distal end. A first tool is sized and configured to be selectively inserted into the shaft and selectively removed from the shaft. The tool includes a region that, when the first tool is inserted into the shaft, is capable of being aligned with and advanced through the side opening to project outside the side opening and contact cancellous bone. A second tool is sized and configured, upon removal of the first tool from the shaft, to introduce into the shaft a bone filling material for discharge through the side opening into the cancellous bone contacted by the first tool.

    摘要： A method and apparatus for filling a cavity in a patient's body with a material are provided. The apparatus can include a flexible tube, a barrel and a plunger. The flexible tube has a first end, a second end, and a lumen extending from the first end to the second end and operable to hold a material for conveyance through the first end into a cavity. The barrel is in fluid communication with the second end of the flexible tube and includes a lumen configured to receive material for delivery into the flexible tube. The plunger is configured to advance material through the lumen in the barrel and into the flexible tube. In one implememtation, there is substantially a one to one ratio of advancement of the plunger to a volume of material advanced from the rigid first end of the flexible tube.
