Diametrically adaptable encapsulated stent and methods for deployment thereof

An endoluminal prosthesis, comprising:

• a self-expanding stent, having an essentially tubular configuration with a central longitudinal lumen, wherein the stent has a luminal surface and an abluminal surface;
• and
• a first seamless tube comprised of expanded polytetrafluoroethylene, covering at least a portion of the luminal surface, and a second seamless tube comprised of expanded polytetrafluoroethylene layer, covering at least a portion of the abluminal surface, wherein the stent is encapsulated between said first and second tubes;
• wherein the encapsulated stent has a reduced first diametric dimension and an expanded second diametric dimension, and wherein the encapsulated stent is adapted to be enlarged to a third diametric dimension;
• wherein the expanded polytetrafluoroethylene is plastically deformed between the second and third diametric dimensions.
