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 The graft and attachment means remain in the vessel after the intraluminal grafting system is withdrawn.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

1. A system for implanting a prothesis in a corporeal lumen having a wall, said system comprising:

a graft having superior and inferior ends, said graft having attachment means located at the superior and inferior ends;

a capsule catheter having an elongate tubular member having proximal and distal ends, said capsule catheter having a proximal capsule positioned at the distal end of the elongate tubular member; and

a balloon catheter disposed within said capsule catheter, said balloon catheter including a second elongate tubular member having proximal and distal ends, an inflatable member positioned proximal the distal end of the second elongate tubular member, and a distal capsule positioned proximate the distal end of the second elongate tubular member;

wherein the superior end of said graft is removably retained in the distal capsule, and the inferior end of said graft is removably retained in the proximal capsule.

2. The system as recited in claim 1, further comprising a capsule jacket slidably positioned coaxially with said capsule catheter and said balloon catheter, wherein the capsule jacket is of sufficient length to cover both the proximal capsule and the distal capsule.

3. The system as recited in claim 1, further comprising:

a control wire slidably disposed in a lumen of the second elongate tubular member, the control wire having a proximal end and a distal end secured to the distal capsule; and

control means connected to the proximal end of the control wire for moving the distal capsule relative to the second elongate tubular member.

4. The system as recited in claim 3, wherein said balloon catheter further comprises a proximal cap secured to the second elongate tubular member, wherein the proximal cap is configured and positioned to be slidably retained within the distal capsule.

5. The system as recited in claim 1, wherein the attachment means of said graft is self-expanding.

6. The system as recited in claim 5, wherein the attachment means of said graft comprises means for engaging the wall of the corporeal lumen to secure said graft thereto.

7. The system as recited in claim 5, wherein the attachment means of said graft comprises wall engaging members configured to pierce the wall of the corporeal lumen.

8. The system of claim 5, wherein said balloon catheter further comprises pusher means for engaging the attachment means located at the inferior end of said graft, the pusher means being slidably disposed on the second elongate tubular member proximal said inflatable member.

9. The system of claim 8, wherein said balloon catheter further comprises retaining means fixedly positioned on the second elongate tubular member proximal the pusher means for preventing proximal movement of the pusher means.

10. The system of claim 1, wherein said balloon catheter further comprises a through lumen extending from the proximal end to the distal end of the second elongate tubular member, and an inflation lumen extending from the proximal end to proximate the distal end of the second elongate tubular member and being in fluid communication with the inflatable member.

11. The system of claim 10, wherein the proximal end of the second elongate tubular member of said balloon catheter is bifurcated to form a first arm and a second arm, the first arm having a lumen in communication with the through lumen and configured to releasably secure a guidewire, the second arm having a lumen in fluid communication with the inflation lumen and configured to accept means for inflating said inflatable member.

12. A system for implanting a prothesis proximate an aortic bifurcation having an aneurism, said system comprising:

a graft having superior and inferior ends, said graft having attachment means located at the superior and inferior ends;

a capsule catheter having an elongate tubular member having proximal and distal ends, said capsule catheter having a proximal capsule positioned at the distal end of the elongate tubular member;

a balloon catheter disposed within said capsule catheter, said balloon catheter including a second elongate tubular member having proximal and distal ends, an inflatable member positioned proximal the distal end of the second elongate tubular member, and a distal capsule positioned proximate the distal end of the second elongate tubular member; and

a capsule jacket slidably positioned coaxially with said capsule catheter and said balloon catheter, wherein the capsule jacket is of sufficient length to cover both the proximal capsule and the distal capsule such that the superior end of said graft is removably retained in the distal capsule, and the inferior end of said graft is removably retained in the proximal capsule.
