Abstract

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.
