Abstract
Abstract An inflatable intraluminal stent for attachment to the interior surface of a tubular structure within the human body is disclosed. The stent features a cuff having an inflatable chamber and a friction-enhancing outer surface. The friction-enhancing outer surface engages the interior surface of the tubular structure without penetration when the inflatable cuff is in an inflated condition. An intraluminal medical device may be attached to the inner surface of the stent. A valve is integral with the inflatable cuff and allows for the inflation, deflation and sealing of the inflatable cuff.

Claims Analysis
Total Claims: 27
Claim 1
Independent Claim
146 words
An inflatable intraluminal stent adapted to be secured to the interior of a tubular structure within the human body comprising: a) an inflatable and deflatable cuff of generally hollow cylindrical continuation having a collapsible lumen, an inner surface, an inlet, an outlet and a friction enhancing outer surface, said friction-enhancing outer surface featuring inflatable protrusion(s) including at least one circumferential ridge disposed about the inflatable cuff, said friction-enhancing outer surface engaging the interior of the tubular structure without penetration to prevent the cuff from moving in a longitudinal direction with respect to the tubular structure when said cuff is in a fully inflated condition; b) means for injecting an inflation material into said cuff to inflate it; and c) a valve integral with the inflatable cuff for permitting entry of the inflation material from the means for injecting and thereafter sealing said cuff to prevent deflation.
