Abstract

A system and method for endoscopically forming an anastomosis between two naturally adjacent points in the digestive tract. The system and method utilizes elongate magnetic devices that, when connected across a tissue boundary, necrose tissue until an anastomosis forms and the devices are passed naturally. Despite the elongate shape of the devices, the resulting anastomosis is substantially round. As such, round anastomoses can be formed having increased diameters merely by increasing the lengths of the devices, obviating the need for wider endoscopes.

Claims

1. A method of forming a round anastomosis comprising:

positioning two devices on either side of a desired anastomosis site such that tissue is compressed between said two magnets;

wherein each of said devices comprises a single elongate magnet having a length that is approximately half of a desired circumference of a resulting anastomosis;

wherein each of said devices has a width of less than 7 mm.

2. The method of claim 1 wherein each of said devices has a width in the range of 1.5 mm to 7 mm.

3. The method of claim 1 wherein each of said devices has a width in the range of 1.5 mm to 3.7 mm.
