Introducer for endoluminal prosthesis

摘要

The present invention provides an introducer (100) for delivering into the vasculature at an angeological bifurcation where a blood vessel branches into two branched vessels a bifurcated endoluminal stent (10) or prosthesis (50;70;91) having a proximal portion (12;62;72;92) adapted to be disposed in said blood vessel and a distal portion (16;80;94) adapted to be disposed at least partially in one of said two branched vessels, said introducer comprising a tubular outer sheath (101) and a proximal portion pusher (102) slideably disposed at least partially within said outer sheath and adapted to engage said proximal portion (12;62;72;92) of said stent (10); characterised by a distal portion pusher (103) slideably disposed at least partially within said proximal portion pusher and adapted to engage said distal portion (16;80;94) of said stent (10). Said introducer may further comprise a balloon catheter (104) having a balloon attached thereto, disposed at least partially within said distal pusher portion.
