Abstract
Abstract An intraluminal grafting system (50) having a balloon catheter assembly (51), a capsule catheter assembly (52) and capsule jacket assembly (53) is used for deploying a graft (55) having attachment means in the vessel of an animal body. The system (50) contains a proximal capsule means (130) and a distal capsule means (90), wherein the graft (55) is disposed within the two capsule means (90,130) and a removable sheath (160) covers the graft (55) and capsule means (90,130). The graft (55) is comprised of a tubular member having superior and inferior ends, having attachment means with wall engaging members secured thereto. The balloon catheter (51) is disposed within the capsule catheter (52) to provide relative movement between the balloon catheter (51) and the capsule catheter (52), whereby the graft (55) can be removed from the capsule means (90,130). The balloon (60) is inflated to firmly implant the graft (55) and attachment means within the vessel. The graft (55) and attachment means remain in the vessel after the intraluminal grafting system (50) is withdrawn. The balloon catheter (51) comprises an elongate tubular member (61) having a proximate end and a distal end, the balloon (60) positioned proximate the distal end of said elongate tubular member (61), wherein said balloon catheter further includes said capsule assembly (90) positioned proximate the distal end of said elongate tubular member (61), and a pusher device (85) disposed on said elongate tubular member (61) proximate said balloon (60). <IMAGE>

A system for implanting a prothesis in a corporeal
lumen having a wall, said system comprising: a graft (55) having a superior end (171) and an
inferior end (172), said graft (55) having a first
attachment system (175) located at the superior end
(171) and a second attachment system (176) located at

member (131) having proximal and distal ends; and a balloon catheter (51) disposed within said
capsule catheter (52), said balloon catheter (51)
including a second elongate tubular member (61) having
proximal and distal ends, and an inflatable member (60)
positioned proximal the distal end of the second
elongate tubular member (61), characterised in that said
capsule catheter (52) further includes a proximal
capsule (132) positioned at the distal end of the
elongate tubular member (131) and said balloon catheter
(51) further includes a distal capsule (93) positioned
proximate the distal end of the second elongate tubular
member (61), wherein the superior end (171) of said
graft (55) is removably retained in the distal capsule
(93), and the inferior end (172) of said graft (55) is
removably retained in the proximal capsule (132).
Claim 2
Dependent Claim
52 words
The system as recited in claim 1, further comprising
a capsule jacket (53) slidably positioned coaxially with said
capsule catheter (52) and said balloon catheter (51), wherein
the capsule jacket (53) is of sufficient length to cover both
the proximal capsule (132) and at least a portion of the distal
capsule (93).
Claim 3
Dependent Claim
75 words
The system as recited in claim 1 or 2, further
comprising: a control wire (91) slidably disposed in a lumen (65)
of the second elongate tubular member (61), the control wire
