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can be releasably secured to the tubular member in such as manner that it can be detached from the tubular member and withdrawn after the elongated element is passed through the side opening and placed in a desired position.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. Tubular prosthesis for deployment in a human body passageway comprising:

a tubular member adapted for placement in a passageway in a human body, said tubular member having an expanded state, a tubular wall with an inner wall surface, first and second end openings, and a side opening formed in said tubular wall between said first and second end openings;

a tube having a first end portion and a second end portion, said first end portion being disposed in said tubular member and extending toward said side opening, wherein the first end portion comprises a distal end opening that faces the first end opening of the tubular member; and

a securing mechanism, said tube being secured to said tubular member inner wall surface through said securing mechanism when said tubular member is in said expanded state, said tube being secured to said tubular member inner wall surface such that it does not pass through said side opening, whereby an elongated element can be passed through said tube and out from said side opening in said tubular wall and said tube can be detached from said tubular member so that it can be moved relative to and withdrawn over the elongated element.

2. The tubular prosthesis of claim 1, wherein the tube end overlaps said side opening.

3. The tubular prosthesis of claim 1, where said tubular member is a tubular graft.

4. The tubular prosthesis of claim 1, wherein said tubular member is a stent-graft.

5. The tubular prosthesis of claim 1, wherein said securing mechanism forms an attachment between said tube and tubular member.

6. The tubular prosthesis as in claim 1 wherein the securing mechanism comprises an adhesive, a suture, or a wire.

7. The tubular prosthesis of claim 1, wherein said securing mechanism is releasable to release said tube from said tubular member.

8. The tubular prosthesis claim 7, further including a second side opening formed in said tubular member 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 tubular member and extending toward said second side opening, and said second tube being releasably secured to said tubular member, whereby a second elongated element can be passed through said second tube and out from said second side opening in said tubular wall and said second tube can be detached from said tubular member so that it can be moved relative to and withdrawn over the second elongated element.

9. The tubular prosthesis of claim 8, wherein one of said tubes has an end in the vicinity of one of said side openings and the other of said tubes has an end in the vicinity of the other of said side openings.

10. The tubular prosthesis of claim 9, wherein one of said tube ends overlaps one of said side openings and the other of said tube ends overlaps the other of said side openings.

11. The tubular prosthesis of claim 1, wherein said tube extends out from said tubular prosthesis second end.

12. The tubular prosthesis of claim 11, further including a second side opening formed in said tubular member 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 tubular member and extending toward said second side opening, and said second tube being secured to said tubular member, whereby a second elongated element can be passed through said second tube and out from said second side opening in said tubular wall and said second tube can be detached from said tubular member so that it can be moved relative to and withdrawn over the second elongated element.

14. The tubular prosthesis as in either claim 1 or claim 13, wherein said tube is directly secured to a portion of the tubular member in which the side opening is formed.

13. Tubular prosthesis for deployment in a human body passageway comprising:

a tubular member adapted for placement in a passageway in a human body, said tubular member having an expanded state, a tubular wall, first and second end openings, and a side opening formed in said tubular wall between said first and second end openings;

a tube having a first end portion and a second end portion, said first end portion being disposed in said tubular member and extending toward said side opening, wherein the first end portion comprises a distal end opening that faces the first end opening of the tubular member; and

a securing mechanism, said tube being secured to said tubular member through said securing mechanism when said tubular member is in said expanded state, whereby an elongated element can be passed through said tube and out from said side opening in said tubular wall, said tube detached from said tubular member so that it can be moved relative to and withdrawn over the elongated element, and a secondary prosthetic device delivered over said elongated element and through said side opening.

15. The tubular prosthesis of claim 13, wherein said securing mechanism is releasable to release said tube from said tubular member.

16. The tubular prosthesis of claim 13, where said tubular member is a tubular graft.

17. The tubular prosthesis of claim 13, wherein said tubular member is a stent-graft.

18. The tubular prosthesis of claim 13, further including a second side opening formed in said tubular member 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 tubular member and extending toward said second side opening, and said second tube being secured to said tubular member, whereby a second elongated element can be passed through said second tube and out from said second side opening in said tubular wall and said second tube can be detached from said tubular member so that it can be moved relative to and withdrawn over the second elongated element.

19. The tubular prosthesis of claim 13, wherein said securing mechanism forms an attachment between said tube and tubular member.

20. The tubular prosthesis as in claim 13 wherein the securing mechanism comprises an adhesive, a suture, or a wire.

21. A tubular prosthesis comprising:

a tubular member adapted for placement in a passageway in a human body, wherein the tubular member comprises an inner wall surface, wherein the tubular member defines a first end opening, a second end opening and a side opening formed in the inner wall surface between the first and second end openings, wherein a guide tube axis extends through the tubular member between the first and second end openings;

a guide tube located in the tubular member, the guide tube aligned with the guide tube axis from the first end opening of the tubular member to a distal end of the guide tube, wherein the guide tube does not pass through the side opening, and wherein the guide tube comprises a guide tube opening located in the tubular member at the distal end of the guide tube, and further wherein the guide tube opening faces the side opening of the tubular member; and

an elongated element configured to pass through the guide tube and out of the guide tube opening before passing through the side opening of the tubular member, wherein the guide tube is configured to be detached from the inner wall surface of the tubular member and moved relative to and withdrawn over the elongated element.
