Publication number: 20040073293Abstract: A prosthesis for transluminal implantation consists of a flexible tubular three-dimensionally braided structure of metal or polymeric monofilaments, and polymeric multifilament yarns. The prosthesis can be elastically deformed to reduce its diameter through axial elongation. The monofilaments and multifilament yarns are arranged in axially spaced apart helices, concentric on a common central axis of the prosthesis. The monofilaments are selectively shaped before their interbraiding with the multifilament yarns, either by an age-hardening or other heat-setting stage, or a cold-working stage that controllably plastically deforms the strands. The shaped structural strands cooperate to impart to the prosthesis its nominal shape and resilience. The textile strands cooperate to provide one or more layers of sheeting that reduce permeability and thereby enhance the utility of the prosthesis as a vascular graft.Type: ApplicationFiled: July 15, 2003Publication date: April 15, 2004Inventor: Paul J. Thompson

Publication number: 20040044396Abstract: An implantable stent and stent-graft for treating a patient having a relatively healthy first aorta portion upstream from a renal artery branch, and a diseased aorta portion downstream from the renal artery branch. One embodiment of the device includes a fixation section, a renal artery branch section and a diseased aorta section, all of which can be tubular, radially compressible and self-expandable structures formed from a plurality of filaments which are helically wound in a braided configuration. When the device is implanted and in its expanded state, the fixation section engages the first aorta portion upstream from a renal artery branch to provide substantial anchoring support. The diseased aorta section engages the portion of the aorta downstream from the renal artery branch and extends across the diseased portion of the aorta for purposes of treatment.Type: ApplicationFiled: February 4, 2003Publication date: March 4, 2004Inventors: Claude O. Clerc, Paul F. Chouinard, Paul J. Thompson

Publication number: 20030229391Abstract: The present disclosure relates to a stent including a stent body having a stent axis. The stent body includes structural members defining openings through the stent body. The structural members are provided with regions having different widths. The relative sizes of the widths are selected to control the length of the stent body as the stent body is radially expanded from an un-deployed orientation to a deployed orientation. In one embodiment, the regions having different widths are provided by tapering the widths of selected segments of the structural member.Type: ApplicationFiled: August 14, 2003Publication date: December 11, 2003Inventor: Paul J.

Publication number: 20030120336Abstract: A intraluminal stent comprises a reticulated tube having an un-deployed diameter and expandable to an enlarged diameter. The tube includes a structural beam extending between first and second ends. The structural beam changes from a first geometry to a second geometry when the tube changes from the un-deployed diameter to the enlarged diameter. The structural beam includes first and second longitudinal elements each extending at least partially between the first and second ends and with a spacing between the first and second elements. Each of said first and second elements changes from the first geometry to the second geometry when the tube changes from the un-deployed diameter to the enlarged diameter for the spacing to remain substantially unchanged as the tube changes from the un-deployed diameter to the enlarged diameter.Type: ApplicationFiled: January 28, 2003Publication date: June 26, 2003Applicant: Intra Therapeutics, Inc.Inventor: Paul J.

Patent number: 6524334Abstract: The expandable stent-graft generally defines a cylindrical lumen made from a stent having a discontinuous wail that is at least substantially covered with an expanded polytetrafluoroethylene material. The expanded polytetrafluoroethylene covering may be a biaxially oriented, expanded polytetrafluoroethylene material having nodules and longitudinal and circumferential fibrils or a uniaxially oriented. expanded polytetrafluoroethylene material.

Patent number: 6500203Abstract: A stent graft for transluminal implantation includes a resilient tubular interbraided latticework of metal or polymeric monofilaments, a tubular interbraided sleeve of polymeric multifilament yarns, and an adhesive layer between the sleeve and latticework for bonding them together. The monofilaments and multifilament yarns are arranged in respective sets of axially spaced apart and oppositely directed helices, concentric on a common axis of the stent graft. The respective braid angles of the monofilaments and multifilament yarns are carefully matched to ensure that the latticework and sleeve behave according to substantially the same relationship governing the amount of radial reduction that accompanies a given axial elongation. According to a process for fabricating the stent graft, the latticework and sleeve are braided and thermally set independently, then bonded to one another by a silicone polymer adhesive applied evenly to the latticework in a liquid spray that also incorporates an organic solvent.Type: GrantFiled: May 27, 1999Date of Patent: December 31, 2002Assignee: Boston Scientific Scimed, Inc.Inventors: Paul J.
