Abstract

A medical device and procedure is provided for rapidly forming an anastomosis between two viscera, while minimizing the potential of breaching the mural boundary. The medical device (30) generally includes a first magnet assembly (32) and a second magnet assembly (34). Each of the magnet assemblies includes a magnetic core (36,38) defining an axial opening (44,46) and at least one includes a transverse passageway (48,50). The axial openings are sized to correspond with the size of the desired anastomosis. The transverse passageway is size to permit passage of a wire guide therethrough for placement of the first and second magnet assemblies. The medical device approximates the tissues of the two viscera, such that endoscopic excision and affixation of the tissues may be performed to create the anastomosis.

Claims

AMENDED CLAIMS received by the International Bureau on 01 July 2008 (01.07.08); original claim 8 amended; remaining claims unchanged-
5. The medical device of claim 4, wherein the first and second rims are sized to nest within each other.
6. The medical device of claim 5, wherein the first and second axial openings are substantially the same size.
7. The medical device of claim 4, wherein the first and second rims are positioned proximate the outer periphery of the first and second magnetic cores.
8. The medical device of claim 4, wherein the first and second rims are positioned proximate the first and second axial openings of the first and second magnetic cores.
9. The medical device of claim 4, wherein the first and second rims define atraumatic engagement surfaces.
10. The medical device of claim 4, wherein the first and second magnet assemblies are disc shaped.
11. The medical device of claim 1 , wherein the first magnet assembly defines a first rim projecting axially from the first magnetic core, and wherein the second magnet assembly does not include a rim and is sized to nest within the first rim.
