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 The graft and attachment means remain in the vessel after the intraluminal grafting system is withdrawn.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

a graft; and

a delivery catheter having an assembled configuration, the assembled delivery catheter including an inferior end portion, a superior end portion and structure for receiving the graft, the inferior end portion having a first port, a second port and a third port;

wherein at least one of the first port and the second port is slidably movable longitudinally relative to the third port.

2. The system of claim 1, wherein the first port is configured to receive a guidewire.

3. The system of claim 1, wherein the second port is configured to receive an inflation syringe.

4. The system of claim 1, wherein the third port is configured to receive a dye injecting syringe.

5. The system of claim 1, the delivery catheter further comprising an elongate member including at least three lumens extending substantially a length thereof.

6. The system of claim 1, the delivery catheter further comprising an elongate member having a first lumen, a second lumen and a third lumen extending substantially a length thereof.

7. The system of claim 6, wherein the first lumen is configured to receive a guidewire.

8. The system of claim 7, wherein the first lumen is in communication with the first port.

9. The system of claim 6, wherein the second lumen is configured to receive inflation pressure.

10. The system of claim 9, wherein the second lumen is in communication with the second port.

11. The system of claim 6, wherein the third lumen is configured to receive a control wire assembly.

12. The system of claim 11, further comprising a control wire assembly, wherein the control wire assembly extending in a superior direction and is connected to a lead end of the delivery catheter, the lead end having an atraumatic profile.

13. The system of claim 1, wherein the third port is associated with an elongate tubular structure having an internal lumen sized to slidably receive structure associated with at least one of the first port and the second port.
