Methods and apparatus for magnet-induced compression anastomosis between adjacent organs
First Claim
1. A method of creating a compression anastomosis between a gallbladder and an adjacent organ, said method comprising the steps of:
- a) placing a first magnet within the adjacent organ such that the first magnet is proximate to a wall of the organ and adjacent to the gallbladder;
b) placing one or more second magnets or magnetic materials in the gallbladder with a biliary catheter or an endoscopic ultrasound guided fine needle aspiration needle, without creating a stoma in the gallbladder, such that the first magnet and the one or more second magnets are magnetically attracted to one another through a defined tissue area of the combined thickness of a wall of the gallbladder and the wall of the adjacent organ and exert compressive forces on the defined area; and
c) removing the first magnet and the one or more second magnets when a compression anastomosis has formed in the defined tissue area.

Abstract
Methods and apparatus for creating an anastomosis or fistula between the gallbladder and an adjacent organ are disclosed. First, a parent magnet, typically a permanent magnet, is deployed in the stomach, small intestine, or another organ adjacent to the gallbladder, and a mating daughter material is deployed in the gallbladder in order to create a magnet-compression anastomosis. The gallbladder may then be ablated or otherwise functionally inactivated through the anastomosis. Another aspect of the invention relates to an all-in-one surgical kit that contains all the necessary specialized tools for a surgeon to perform the procedure.

10. A method of at least partially inactivating a gallbladder, comprising:
-
placing a first magnet proximate to a wall of an adjacent organ proximate to the gallbladder; introducing one or more second magnets or magnetic materials into the gallbladder with a biliary catheter or an endoscopic ultrasound guided fine needle aspiration needle, without creating a stoma in the gallbladder, such that the first magnet and the one or more second magnets are magnetically attracted to one another through a defined tissue area of the combined thickness of a wall of the gallbladder and the wall of the adjacent organ and exert compressive forces on the defined area; allowing the tissue in the defined area to necrose to create an anastomosis between the gallbladder and the adjacent organ; removing the first magnet and the one or more second magnets; and selectively inducing gallbladder scarring or damage through the anastomosis. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)
