Patent number: 8790241Abstract: A method for making a radially expandable stent-graft, including positioning a radially expandable stent member concentrically over a first polymeric member, locating a second polymeric member concentrically over the stent member and first polymeric member, and joining the first polymeric member to the second polymeric member through interstices of the stent member at selective locations to form slip planes between the first and second polymeric members. The slip planes accommodate movement of the stent between the polymeric members to facilitate compression of the stent graft to a low profile.Type: GrantFiled: September 2, 2011Date of Patent: July 29, 2014Assignee: Bard Peripheral Vascular, Inc.Inventors: Tarun J.

Publication number: 20140107766Abstract: A device includes a tubular substrate and a support member. The support member includes a component that is elastically deformable and elastically recoverable. The support member wraps around and adheres to an abluminal surface of the tubular substrate. The device is adapted for use in an anatomical conduit. For example, the device may be adapted for bypassing an anatomical conduit, for creating an arteriovenous shunt, or as a support structure for maintaining an opening in an anatomical conduit.Type: ApplicationFiled: December 13, 2013Publication date: April 17, 2014Applicant: BARD PERIPHERAL VASCULAR, INC.Inventors: Christopher E.

Publication number: 20140096906Abstract: A method for making an encapsulated stent includes providing first and second ePTFE layers and a stent positioned therebetween. The first ePTFE layer may be unsintered and have a node-fibril microstructure in which the fibrils are oriented perpendicular to the longitudinal axis. The second ePTFE layer may be unsintered and have a node-fibril microstructure in which the fibrils are oriented parallel to the longitudinal axis. The method includes joining the first ePTFE layer to the second ePTFE layer through openings in a wall of the stent.Type: ApplicationFiled: December 13, 2013Publication date: April 10, 2014Applicant: BARD PERIPHERAL VASCULAR, INC.Inventors: Tarun J.
