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 device for forming a substantially round anastomosis having a radius (r) comprising:

a first elongate component having a length (l) and a width (w); and

,

a second elongate component magnetically attracted to said first component and having a length (l) and a width (w);

wherein width (w) is narrow enough to fit within a working channel of a standard endoscope; and

,

wherein length (l) is related to a desired radius (r) of a resulting, substantially round anastomosis according to the formula (l)=(Π

)(r)−

(w).

2. The device of claim 1 wherein (w) is less than 7 mm.

3. The device of claim 2 wherein (w) is between 1.5 mm and 7 mm.

4. The device of claim 3 wherein (w) is between 1.5 mm and 3.7 mm.

5. A system for forming an anastomosis in a digestive tract of a patient comprising:

first and second probes, each probe defining at least one lumen slidingly housing an attachment mechanism and each probe having an optic lens;

a first device carried by said first probe and attached thereto by said attachment mechanism, said first device comprising;

a magnet;

a housing at least partially encasing said magnet, said housing defining a connector releasably and repeatably engageable by said attachment mechanism;

a second device carried by said second probe and attached thereto by said attachment mechanism, said second device comprising;

an element attracted to said magnet of said first device;

a housing at least partially encasing said element, said housing defining a connector releasably and repeatably engageable by said attachment mechanism.

6. The system of claim 5 wherein:

said first device has a length (l) and a width (w);

wherein width (w) is narrow enough to fit within a working channel of a standard endoscope; and

,

wherein length (l) is related to a desired radius (r) of a resulting, substantially round anastomosis according to the formula (l)=(Π

r)−

(w).

7. The device of claim 6 wherein (w) is less than 7 mm.

8. The device of claim 7 wherein (w) is between 1.5 mm and 7 mm.

9. The device of claim 8 wherein (w) is between 1.5 mm and 3.7 mm.

10. The device of claim 5 wherein said connector comprises a knob.

11. The device of claim 5 wherein said connector comprises a loop.
