Abstract
Abstract The present invention provides controlled expansion endoluminal prostheses and methods for their deployment and expansion. The present stent-grafts generally comprise a radially expansible tubular frame and a plastically expansible liner on the frame. Either the frame or the liner includes a reinforcing element which limits expansion of the stent-graft at a predetermined expanded size. In some embodiments, the reinforcing element restrains the frame, for example, by limiting the circumferential diagonals of perforations on a perforate frame structure. Generally, however, the reinforcing element is included in the liner as circumferentially oriented yarn. A particularly advantageous liner includes composite circumferential yarns having inexpansible fibers wrapped around an expansible fiber, such as a partially oriented yarn, PTFE, or the like.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
95 words
A cuffed, endoluminal stent-graft, comprising: a radially expansible tubular frame having an inner surface and an outer surface; a tubular liner disposed on at least one of the inner and the outer surfaces of the frame, the liner having an axial end, wherein expansion of the stent-graft along the liner is limited to a predetermined, expanded cross-section; and a sealing cuff adjacent to the axial end of the liner, wherein the sealing cuff is extendable radially beyond the liner and frame so as to seal between the liner and frame and a surrounding body lumen.
Claim 2
Dependent Claim
95 words
A cuffed, endoluminal stent-graft, comprising: a radially expansible tubular frame having an inner surface and an outer surface; a tubular liner disposed on at least one of the inner and the outer surfaces of the frame, the liner having an axial end, wherein expansion of the stent-graft along the liner is limited to a predetermined, expanded cross-section; and a sealing cuff adjacent to the axial end of the liner, wherein the sealing cuff is extendable radially beyond the liner and frame so as to seal between the liner and frame and a surrounding body lumen.
