Abstract
Abstract 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.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
125 words
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).
Claim 2
Dependent Claim
37 words
An introducer (100) for delivering a bifurcated endoluminal stent or prosthesis as claimed in claim 1 characterised by a balloon catheter (104), having a balloon (107) attached thereto, disposed at least partially within said distal portion pusher.
Claim 3
Dependent Claim
35 words
An introducer for delivering a bifurcated endoluminal stent or prosthesis as claimed in claim 1 or claim 2 further comprising a hemostasis valve (114) attached to the distal end of said distal portion pusher (103).
Claim 4
Dependent Claim
35 words
An introducer for delivering a bifurcated endoluminal stent or prosthesis as claimed in claim 1, claim 2 or claim 3 further comprising wings (112,113) on said outer sheath (101) and said proximal portion pusher (102).
Claim 5
Dependent Claim
31 words
An introducer for delivering a bifurcated endoluminal stent or prosthesis as claimed in claim 2, wherein said balloon catheter (104) has an injection orifice (109) and an injection conduit (109a) therein.
Claim 6
Dependent Claim
31 words
An introducer for delivering a bifurcated endoluminal stent or prosthesis as claimed in claim 2, wherein said balloon catheter (104) has an inflation orifice (110) and an inflation conduit (110a) therein.
Claim 7
Dependent Claim
32 words
An introducer for delivering a bifurcated endoluminal stent or prosthesis as claimed in claim 2, wherein said balloon catheter (104) has a proximal end (105) with a nose cone (106) attached thereto.
Claim 8
Dependent Claim
113 words
A combination of an apparatus for delivering an endoluminal stent or prosthesis into the vasculature and a stent contained therein comprising: (a) an introducer (300) having a first portion (310) of a lock fitting on a distal end thereof; and (b) a cartridge (311) having an inner tubular member (314) containing said stent or prosthesis in a compressed state, an outer sheath (313), and a second portion of said lock fitting (312); wherein said first portion of said lock fitting on said introducer mates with said second portion of said lock fitting on said cartridge to prevent relative movement of said introducer and said cartridge when connected to one another in axial juxtaposition.
Claim 9
Dependent Claim
14 words
Apparatus as claimed in claim 8 wherein said lock fitting is a Luer lock.
Claim 10
Dependent Claim
40 words
Apparatus as claimed in claim 8 or claim 9 further comprising a hemostasis valve (361) on said introducer and a pusher (315) adapted to push said compressed stent or prosthesis through said cartridge, through said introducer, and into the vasculature.
