Abstract
Abstract An intraluminal grafting system having a balloon catheter assembly, a capsule catheter assembly and capsule jacket assembly is used for deploying a graft having attachment means in the vessel of an animal body. The system contains a proximal capsule means and a distal capsule means, wherein the graft is disposed within the two capsule means and a removable sheath covers the graft and capsule means. The graft is comprised of a tubular member having superior and inferior ends, having attachment means with wall engaging members secured thereto. The balloon catheter is disposed within the capsule catheter to provide relative movement between the balloon catheter and the capsule catheter, whereby the graft can be removed from the capsule means. The balloon is inflated to firmly implant the graft and attachment means within the vessel. The graft and attachment means remain in the vessel after the intraluminal grafting system is withdrawn.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
82 words
A balloon catheter comprising: an elongate tubular member having a first lumen, a second lumen, a proximal end and a distal end; an inflatable member in fluid communication with said second lumen and positioned proximate the distal end of said elongate tubular member; means for removably retaining a prothesis, said means positioned proximate the distal end of said elongate tubular member; and a means for engaging a prosthesis, said engaging means being disposed on said elongate tubular member proximate said inflatable member.
Claim 2
Dependent Claim
82 words
A balloon catheter comprising: an elongate tubular member having a first lumen, a second lumen, a proximal end and a distal end; an inflatable member in fluid communication with said second lumen and positioned proximate the distal end of said elongate tubular member; means for removably retaining a prothesis, said means positioned proximate the distal end of said elongate tubular member; and a means for engaging a prosthesis, said engaging means being disposed on said elongate tubular member proximate said inflatable member.
Claim 3
Dependent Claim
76 words
The balloon catheter of claim 1, further comprising: a third lumen extending from proximate the proximal end to proximate the distal end of said elongate tubular member; a control wire slidably disposed in said third lumen, said control wire having a proximal end and a distal end secured to said capsule means; and control means connected to the proximal end of said control wire for moving said retaining means in relation to said elongate tubular member.
Claim 4
Dependent Claim
57 words
The balloon catheter of claim 2, wherein said retaining means comprises a distal capsule and a proximal cap, the distal capsule being secured to the distal end of said control wire for removably retaining a prothesis, the proximal cap being coaxially secured to the elongate tubular member and configured to be slidably retained in the distal capsule.
Claim 5
Dependent Claim
64 words
The balloon catheter of claim 3, wherein said control means comprises: a handle positioned distal of the proximal end of said elongate tubular member; and means for locking said control wire such that movement of the locking means causes movement of said distal capsule, wherein the locking means is configured to be releasably secured to the handle to prevent movement of said control wire.
Claim 6
Dependent Claim
33 words
The balloon catheter of claim 4, wherein said control means further comprises a hypotube secured within the handle and secured coaxially over a portion of said elongate tubular member distal of the handle.
Claim 7
Dependent Claim
68 words
The balloon catheter of claim 1, wherein the proximal end of said elongate tubular member is bifurcated to form a first arm and a second arm, the first arm having a lumen in communication with said first lumen and configured to releasably secure a guidewire, the second arm having a lumen in fluid communication with said second lumen and configured to accept means for inflating said inflatable member.
Claim 8
Dependent Claim
22 words
The balloon catheter of claim 1, wherein said engaging means is slidably disposed on said elongate tubular member proximal said inflatable member.
Claim 9
Dependent Claim
32 words
The balloon catheter of claim 7, further comprising a retaining bump fixedly positioned on said elongate tubular member proximal said engaging means so as to prevent proximal movement of said engaging means.
Claim 10
Dependent Claim

A balloon catheter comprising: an elongate tubular member having a proximate end and a distal end; an inflatable member positioned proximate the distal end of said elongate tubular member; a capsule assembly positioned proximate the distal end of said elongate tubular member; and a pusher device disposed on said elongate tubular member proximate said inflatable member.
Claim 11
Dependent Claim
56 words
A balloon catheter comprising: an elongate tubular member having a proximate end and a distal end; an inflatable member positioned proximate the distal end of said elongate tubular member; a capsule assembly positioned proximate the distal end of said elongate tubular member; and a pusher device disposed on said elongate tubular member proximate said inflatable member.

The balloon catheter of claim 9, further comprising: a control wire having a proximal end and distal end secured to said capsule assembly; and a controller assembly connected to the proximal end of said control wire for moving said capsule assembly in relation to said elongate tubular member.
Claim 13
Dependent Claim
57 words
