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： A method of making an implantable medical device includes extruding a first ePTFE tube and a second ePTFE tube, cutting a plurality of slits in the first ePTFE tube, positioning a radially expandable support layer between the first and second ePTFE tubes so that the slits span portions of the support layer, and laminating the first ePTFE tube to the second ePTFE tube through openings in the support layer.
