Abstract

Tubular prosthesis for deployment in a human body passageway comprises a tubular member adapted for placement in a passageway in a human body and a tube. The tubular member has a tubular wall, first and second end openings, and a side opening formed in the tubular wall between the first and second end openings. The tube has a first end portion and a second end portion. The first end portion of the tube is disposed in the tubular member and has an opening arranged relative to the side opening such that an elongated element (e.g., a guidewire) can be passed through the tube and out from the side opening in the tubular wall where it can enter a branch passageway. The tube can be releasably secured to the tubular member in such as manner that it can be detached from the tubular member and withdrawn after the elongated element is passed through the side opening and placed in a desired position.

Claims

1. A tubular prosthesis delivery system comprising a delivery catheter having a proximal end portion and a distal end portion, a tubular prosthesis comprising a tubular wall, first and second end openings, and a side opening formed in said tubular wall between said first and second end openings, said prosthesis being positioned in said distal end portion of said delivery catheter, and a tube having a first end portion and a second end portion, said tube first end portion being disposed in said tubular prosthesis and having an end opening in the vicinity of said side opening and said tube second end portion extending to said proximal end portion of said delivery catheter, wherein said delivery catheter comprises a sheath and a pusher rod slidably disposed therein, said pusher rod having a lumen formed therein and extending in an axial direction thereof, and said tube extending through said pusher rod lumen.

2. The delivery system of claim 1, wherein said pusher rod comprises an end portion facing said tubular prosthesis.

3. The delivery system of claim 2, wherein said tube is releasably secured to said tubular prosthesis.

4. The delivery system of claim 3 wherein said tube is releasably secured to said tubular prosthesis with adhesive.

5. The delivery system of claim 3 wherein said tube is releasably secured to said tubular prosthesis with a suture.

6. The delivery system of claim 3 wherein said tube is releasably secured to said tubular prosthesis with a wire.

7. The delivery system of claim 3 wherein said sheath and said pusher rod are axially movable relative to each other.

8. The delivery system of claim 1, wherein said tube is releasably secured to said tubular prosthesis.

9. The delivery system of claim 1, wherein a guidewire extends through at least a portion of said lumen and said tube.

10. The delivery system of claim 1, wherein said prosthesis has a radially collapsed state and a radially expanded state, said tubular prosthesis being in said collapsed state.

11. The delivery system of claim 1, further including a second side opening formed in said prosthesis between said first and second end openings and a second tube having a first end portion and a second end portion, said second tube first end portion being disposed in said prosthesis and extending toward said second side opening.

12. The delivery system of claim 11 wherein said second tube is releasably secured to said prosthesis.

13. The delivery system of claim 11 wherein a second guidewire can be passed through said second tube and out from said second side opening in said prosthesis.

14. The delivery system of claim 11 wherein said pusher rod further comprises a second lumen, said second tube extending through said pusher rod second lumen.

15. The delivery system of claim 1 wherein said pusher rod comprises a central lumen, the delivery system further comprising an inner tube slidably disposed in said pusher rod central lumen.

16. The delivery system of claim 15 wherein said inner tube is configured to receive a guidewire therein.
