Diametrically adaptable encapsulated stent and methods for deployment thereof
First Claim
1. An implantable intraluminal device, comprising a self-expanding stent encapsulated between a first seamless ePTFE tube and a second seamless ePTFE tube, at least one of the tubes being unsintered, an interlayer member comprising a pair of unsintered ePTFE rings disposed between an abluminal surface of the stent and the second ePTFE tube, the implantable intraluminal device having a reduced first diametric dimension and an expanded second diametric dimension, the implantable intraluminal device adapted to be modeled to the in vivo profile of a receiving anatomical structure through radial expansion of at least a portion thereof to a third diametric dimension greater than the second diametric dimension.

Abstract
An implantable intraluminal device having a self-expanding stent encapsulated between a first and second seamless ePTFE tube. The implantable intraluminal device has a reduced first diametric dimension and an expanded second diametric dimension, and is adapted to be modeled to the in vivo profile of a receiving anatomical structure through radial expansion of at least a portion thereof to a third diametric dimension greater than the second diametric dimension.
