INTESTINAL BYPASS USING MAGNETS
First Claim
Patent Images
1. A method of forming an anastomosis between a proximal section of the digestive tract and distal section of the digestive tract, the method comprising the steps of:
- placing a first magnet assembly within the distal section;
placing a second magnet assembly within the proximal section;
forming an opening within a wall of a bodily lumen;
passing medical instrumentation through the opening;
engaging the distal section proximate the first magnet assembly with the medical instrumentation;
moving the distal section such that the first magnet assembly becomes magnetically coupled to the second magnet assembly; and
forming an anastomosis between the proximal and distal sections of the digestive tract proximate the first and second magnet assemblies.

Abstract
Medical devices and methods are provided for forming an intestinal bypass anastomosis, such as for treatment of obesity. The medical devices and methods are minimally invasive and reduce complications. Two magnet assemblies are deployed in a spaced apart relationship, and are transluminally brought together to approximate the tissue and form an anastomosis therebetween.

15. A medical instrument for engaging a first magnet assembly and magnetically coupling the first magnet assembly with a second magnet assembly, the medical instrument comprising:
-
a steerable elongate element having a magnetic portion; a pushing catheter defining a lumen slidably receiving the steerable elongate element; and the second magnet assembly defining an aperture sized to receive the steerable elongate element such that the second magnet is positioned on the outer periphery of the steerable elongate element, wherein relative translation of the pushing catheter and steerable elongate element causes the second magnet assembly to move distally over the steerable elongate element for engagement with the first magnet assembly. - View Dependent Claims (16, 17, 18, 19, 20)
