Abstract

A system and method for treating obesity including a first instrument containing a first magnet therein, the first instrument insertable into a stomach of a patient and the first magnet deployable into the stomach of the patient and having a first space. A second instrument contains a second magnet therein, the second instrument insertable into a bowel of a patient and the second magnet deployable into the bowel of the patient and having a second space. A stent is insertable into the first and second spaces to maintain an opening formed between the stomach and bowel.

First claim

What is claimed is:

1 . A method for treating obesity comprising the steps of:
inserting first and second endoscopes, the first endoscope inserted into a stomach of the patient and the second endoscope inserted into a bowel of a patient; approximating the stomach and bowel; deploying a first magnet in the stomach and a second magnet in the bowel; creating an opening between the stomach and bowel; and positioning a stent into the opening.

2 . The method of claim 1 , further comprising the step of delivering a penetrating device to penetrate a wall of the stomach and a wall of the bowel.

3 . The method of claim 1 , wherein the step of inserting the first endoscope into the stomach includes advancing the first endoscope transorally into the stomach.

4 . The method of claim 1 , further comprising the step of inserting a T-bar through a wall of the stomach and a wall of the bowel and the step of approximating the stomach and bowel includes the step of pulling the T-bar proximally.

5 . The method of claim 1 , wherein the first magnet is deployed from the first endoscope and the second magnet is deployed from the second endoscope.

6 . The method of claim 5 , wherein the first magnet has a first opening and the second magnet has a second opening, and the step of creating an opening between the stomach and the bowel includes inserting a cutting instrument through the first and second openings of the magnets.

7 . The method of claim 1 , wherein the first magnet is retained in the first endoscope in a substantially linear position and the first magnet moves to a curved placement position after deployment from the first endoscope.

8 . The method of claim 7 , wherein the second magnet is retained in the second endoscope in a substantially linear position and the second magnet moves to a curved placement position after deployment from the second endoscope.

9 . The method of claim 1 , wherein the first endoscope has a first channel to receive the first magnet and a second channel to receive a device for approximating the stomach and bowel, and the step of deploying the first magnet advances the first magnet from the first channel.

10 . The method of claim 9 , wherein the first endoscope has a third channel to receive the stent and the step of positioning the stent in the opening includes the step of advancing the stent from the third channel.

11 . The method of claim 1 , further comprising the step of removing the first and second endoscopes and closing off a portion of the stomach.

12 . A system for treating obesity comprising:
a first instrument containing a first magnet therein, the first instrument insertable into a stomach of a patient and the first magnet deployable into the stomach of the patient, the first magnet having a first space; a second instrument containing a second magnet therein, the second instrument insertable into a bowel of the patient and the second magnet deployable into the bowel of the patient, the second magnet having a second space; and a stent insertable into the first and second spaces to maintain an opening formed between the stomach and bowel.

13 . The system of claim 12 , wherein the first magnet is retained in the first instrument in a substantially linear position in the delivery configuration and has a curved placement configuration after deployment from the first instrument.

14 . The system of claim 13 , wherein the second magnet is retained in the second instrument in a substantially linear position in the delivery configuration and has a curved placement configuration after deployment from the second instrument.

15 . The system of claim 12 , wherein the second magnet is retained in the second instrument in a substantially linear position in the delivery configuration and has a curved placement configuration when deployed from the second instrument.

16 . The system of claim 12 , wherein the stent has a first collapsed configuration when positioned in the first instrument and an expanded second position after exposure from the first instrument.

17 . The system of claim 12 , wherein the first instrument has a first channel to receive the first magnet and a second channel to receive a device for approximating the stomach and bowel.

18 . The system of claim 17 , wherein the first instrument has a third channel to receive the stent.

19 . The system of claim 12 , further comprising a T-bar and T-bar delivery instrument positionable within the first instrument.

20 . The system of claim 19 , further comprising a cutting instrument insertable through the first instrument.
