Abstract

An endoscopic or laparoscopic conduit delivery device (1) comprises first and second separately manipulable introducers (3, 5) with a laparoscopic conduit (80) having first and second ends (83, 84) and an intermediate portion being mounted onto the introducers in a substantially U shape. The first end and a first portion of the laparoscopic conduit is retained onto the first introducer and the second end and a second portion of the laparoscopic conduit is retained on the second introducer and the intermediate portion extends between the first and second introducers. A main sheath (42) is over the first and second introducers. The endoscopic or laparoscopic conduit delivery device is introduced to a body cavity through an endoscopic or laparoscopic port (50).

Claims

1. A bypass conduit delivery device comprising:

first and second separately manipulable introducers for carrying a bypass conduit provided with first and second ends and an intermediate portion, the bypass conduit being mountable onto the introducers in a substantially U shape with the first end and a first portion of the bypass conduit retained onto the first introducer and the second end and a second portion of the bypass conduit retained on the second introducer and the intermediate portion extending between the first and second introducers, and

a main sheath over the first and second introducers.

2. A bypass conduit delivery device as in claim 1, wherein the first and second introducers are arranged side by side.

3. A bypass conduit delivery device as in claim 1, wherein for a bypass conduit which includes an aperture in the intermediate portion thereof, the first and second introducers are operable to pass through the aperture in the bypass conduit.

4. A bypass conduit delivery device as in claim 3, wherein the aperture in the bypass conduit is pre-stitched with a suture thread for closure of the aperture after removal of the first and second introducers.

5. A bypass conduit delivery device as in claim 1, wherein each of the first and second introducers comprises a guide wire lumen therein.

6. A bypass conduit delivery device as in claim 1, wherein each of the first and second introducers includes a spliltable sheath co-axially therearound operable to contain the first and second portions of the bypass conduit on the first and second introducers respectively, each splittable sheath including an aperture for allowing the intermediate portion of the bypass conduit to extend between the first introducer and the second introducer through the respective apertures in the sheath.

7. A bypass conduit delivery device as in claim 6, wherein each of the first and second splittable sheaths extends to a sheath manipulator.

8. A bypass conduit delivery device as in claim 1, wherein each of the first and second introducers comprises a pusher with a pusher lumen therethrough, a guide wire catheter extending through the pusher lumen, and a nose cone dilator on the guide wire catheter.

9. A bypass conduit delivery device as in claim 1, wherein the main sheath is provided with a hemostatic seal.

10. A bypass conduit delivery device as in claim 1, wherein the bypass conduit comprises a tubular body of a biocompatible graft material and a plurality of self-expanding stents.

11. A bypass conduit delivery device as in claim 10, wherein at least one of the plurality of self-expanding stents at the first and second ends of the bypass conduit is located on the inside of the tubular body and the other stent or stents of the plurality of stents are located on the outside of the tubular body.

12. A bypass conduit delivery device as claim 1, wherein the bypass conduit includes a corrugated intermediate portion.

13. A bypass conduit delivery device as in claim 1, wherein the bypass conduit comprises a tubular body of a biocompatible graft material, a corrugated intermediate portion and at least one balloon expandable stent at each end thereof and each of the first and second introducers includes an expandable balloon.

14. A bypass conduit delivery device as in claim 1, including a endoscopic access port which includes an access valve incorporating a hemostatic seal.

15. A bypass conduit for use in bypassing a patient'"'"'s vasculature including:

first and second ends and an intermediate portion, an aperture in the intermediate portion and at last one suture thread pre-sewn in a loose manner to the aperture, the bypass conduit being resiliently deformable substantially to a U-shape such that the aperture with the suture thread is open for the passage of introducer elements therethrough.

16. A bypass conduit as in claim 15, wherein the main sheath is provided with a hemostatic seal.

17. A bypass conduit as in claim 15, wherein the bypass conduit comprises a tubular body of a biocompatible graft material and a plurality of self-expanding stents.

18. A bypass conduit delivery device as in claim 17, wherein at least one of the plurality of self-expanding stents at the first and second ends of the bypass conduit is located on the inside of the tubular body and the other stent or stents of the plurality of stents are located on the outside of the tubular body.

19. A bypass device as in claim 15, wherein the bypass conduit comprises a tubular body of a biocompatible graft material, a corrugated intermediate portion and at least one balloon expandable stent at each end thereof.

20. A bypass conduit delivery device in combination with a bypass conduit comprising:

first and second separately manipulable introducers arranged side by side,

a bypass conduit provided with first and second ends and an intermediate portion,

the bypass conduit being mounted onto the introducers substantially in a U-shape with the first end and a first portion of the bypass conduit retained onto the first introducer and the second end and a second portion of the bypass conduit retained on the second introducer and the intermediate portion extending between the first and second introducers, an aperture in the intermediate portion, the first and second introducers passing through the aperture in the bypass conduit, each of the first and second introducers including a splittable sheath co-axially therearound to contain the first and second portions of the bypass conduit onto the first and second introducers respectively, each splittable sheath including an aperture to allow the intermediate portion of the bypass conduit to extend between the first introducer and the second introducer through the respective apertures in the sheath, each of the first and second splittable sheaths extending to a sheath manipulator and each sheath manipulator including a hemostatic seal, and a main sheath over the first and second introducers.
