A composite intraluminal device is deployable within a body vessel. The composite device includes an elongate radially expandable tubular stent having an interior luminal surface and an opposed exterior surface extending along a longitudinal stem axis. A stent cover is formed of unsintered ePTFE which is expandable. The stent cover is positioned about the stent so as to permit expansion of the cover upon the radial expansion of the stent.

Ce dispositif comprend un extenseur tubulaire allongé pouvant se dilater radialement et possédant une surface intérieure luminale et une surface extérieure opposée s'étendant le long de l'axe de la longueur de l'extenseur. Un enrobage recouvrant l'extenseur est constitué par du PTFE non fritté et dilatable.
