Methods and apparatus for magnet-induced compression anastomosis between adjacent organs
First Claim

1. An implantable device for creating an anastomosis, the device comprising:
- an assembly of magnetic segments associated with one another, each of the magnetic segments having opposing poles and directly joined to an immediately adjacent magnetic segment at one of the opposing poles, the assembly configured to transition between a delivery configuration and a deployed configuration;
wherein, when in the delivery configuration, the magnetic segments are aligned end-to-end in a single-file arrangement and the assembly is substantially linear; and
wherein, when in the deployed configuration, the magnetic segments self-assemble into a geometric shape based, at least in part, on an attractive force between immediately adjacent magnetic segments.

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.

11. An implantable device for creating an anastomosis, the device comprising:
an assembly of elongated magnetic segments associated with one another and configured to transition from a compressed delivery configuration, wherein at least two adjacent elongated magnetic segments are substantially parallel and in close proximity with one another, to an expanded deployed configuration, wherein the elongated magnetic segments are configured to self-assemble into a geometric structure based, at least in part, on a repulsive magnetic force between corresponding portions of the at least two adjacent elongated magnetic segments, such that the at least two adjacent elongated magnetic segments are substantially perpendicular to one another in the expanded deployed configuration. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
