Intestinal bypass using magnets

摘要

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.

主权项

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 adjacent the proximal section; passing medical instrumentation through the opening; engaging the distal section proximate the first magnet assembly with the medical instrumentation while the medical instrumentation is passed through the opening and without passing the medical instrumentation through a wall of the distal section; moving the distal section with the medical instrumentation such that the first magnet assembly becomes magnetically coupled to the second magnet assembly, wherein the first and second magnet assemblies are sized and structured to engage over an area and induce necrosis of tissue within the area to form the anastomosis; and forming an anastomosis between the proximal and distal sections of the digestive tract proximate the first and second magnet assemblies.
