Abstract

An adaptor includes a body having a first end and a second end. The first end is configured to be releaseably secured to an anvil shaft of an anvil assembly. The second end is configured to be securely received within a flexible tube to releaseably secure the anvil assembly to the flexible tube. The adaptor and flexible tube assembly facilitates placement of the anvil assembly within the stomach during the performance a minimally invasive gastric bypass procedure.

Claims

1. An anvil delivery adaptor, comprising:

a body having a first end and a second end, the first end being configured to be secured to an anvil shaft of an anvil assembly, the second end being configured to be secured to a flexible tube to releasably secure the anvil assembly to the flexible tube, wherein a flexible arm is formed on the first end, the flexible arm includes a protrusion engagable with the anvil shaft of the anvil assembly and the protrusion engages an opening defined in the anvil shaft of the anvil assembly in a snap-fit arrangement.

2. The anvil delivery adapter of claim 1, wherein the first end of the adaptor is releasably secured to the anvil shaft.

3. The anvil delivery adapter of claim 1, wherein the second end of the adaptor is configured to be received within the flexible tube.

4. The anvil delivery adaptor of claim 1, wherein the protrusion has a tapered face.

5. The anvil delivery adaptor of claim 1, wherein the flexible arm includes a release member that disengages the protrusion from the opening in the anvil shaft of the anvil assembly upon the actuation of the release member.

6. The anvil delivery adapter of claim 1, wherein the first end is integrally formed with the second end.

7. An anvil delivery adaptor, comprising:

a body having a first end and a second end, the first end being configured to be secured to an anvil shaft of an anvil assembly, the second end being configured to be secured to a flexible tube to releasably secure the anvil assembly to the flexible tube, wherein the second end includes a cylindrical member having a plurality of ridges, each ridge being positionable within the flexible tube to facilitate the securement of the cylindrical member to the flexible tube.

8. The anvil delivery adaptor of claim 7, wherein the ridges are tapered.

9. An anvil delivery adaptor, comprising:

a body having a first end and a second end, the first end being configured to be secured to an anvil shaft of an anvil assembly, the second end being configured to be secured to a flexible tube to releasably secure the anvil assembly to the flexible tube, wherein the first end is secured to the second end by a suture.
