Deployment system for intraluminal devices

Abstract From the Canadian patent

A constraining sheath for use around an endoprosthesis (e.g. a sent device with or without a graft covering), which may be a balloon expandable endoprosthesis but more preferably is a self-expanding prosthesis. The endoprosthesis is coaxially enclosed within and substantially covered by the constraining sheath which is an outer, removable tubular sheath preferably made of ePTFE. The sheath is preferably corrugated circumferentially along at least a portion of the length of the endoprosthesis. The constraining sheath and endoprosthesis are preferably mounted together as an assembly at the distal end of a delivery means such as a catheter shaft for delivery of the endoprosthesis to a desired …
