Methods for making encapsulated stent-grafts

Shape memory alloy and elastically self-expanding endoluminal stents which are at least partially encapsulated in a substantially monolithic expanded polytetrafluorethylene ("ePTFE") covering. An endoluminal stent, which has a reduced diametric dimension for endoluminal delivery and a larg...

Zusammenfassung:	Shape memory alloy and elastically self-expanding endoluminal stents which are at least partially encapsulated in a substantially monolithic expanded polytetrafluorethylene ("ePTFE") covering. An endoluminal stent, which has a reduced diametric dimension for endoluminal delivery and a larger in vivo final diametric diameter is encapsulated in an ePTFE covering which circumferentially covers both the luminal and abluminal walls along at least a portion of the longitudinal extent of the endoluminal stent. The endoluminal stent is fabricated from a shape memory alloy which exhibits either shape memory or pseudoelastic properties or from an elastic material having an inherent spring tension.
