Abstract

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.

Independent Claims | See all claims (9)

  1. 1. A radially expandable reinforced vascular graft exhibiting improved flexibility, comprising: an expanded polytetrafluoroethylene layer; a radially expandable support layer comprising at least one stent, wherein said support layer is in contact with a surface of the expanded polytetrafluoroethylene layer; and an expanded polytetrafluoroethylene tube, comprising a tube wall and a plurality of openings, each of the openings extending through the tube wall comprising a longitudinal component and a circumferential component, wherein the length of the longitudinal component is less than the total length of the tube, and wherein the length of the circumferential component is less than 360°; wherein the radial expandable support layer is secured between the expanded polytetrafluoroethylene layer and the expanded polytetrafluoroethylene tube, and wherein at least a portion of the support layer is positioned within the openings.
