Abstract
A system for auto-anastomosing a region of the body using magnetic members that may be individually delivered to different locations in the body. The magnetic members have a polar alignment that generates an attractive force to compress tissue in the region between them. The tissue in the region necroses as a result of the compressive force such that tissue surrounding the necrosed tissue heals together to form an anastomosis. A cutting member may be coupled to either the first or second magnetic member to create a temporary opening in the tissue.
Claims8
A system for auto-anastomosing a region of the body, comprising:
- a. a first implant comprising:
- a body, a first magnet with a first magnetic polarity, a first through-hole, and a terminal annulus defining a convex mating surface, and wherein said convex mating surface has a first radius and
- b. a second implant comprising:
- a body, a second magnet with a second magnetic polarity opposite from said first magnetic polarity, a second through-hole, and a terminal annulus defining a concave mating surface, wherein said concave mating surface extends within the body of said second implant, and wherein said concave mating surface has a second radius, wherein said second radius is greater than said first radius, wherein while said convex mating surface faces said concave mating surface, a magnetic mating of said surfaces causes the terminal annulus of the first implant to extend within the body of the second implant and apply a non-uniform compressive force across two adjacent structures disposed in between said two mating surfaces, wherein said non-uniform compressive force is capable of forming an anastomosis between said two adjacent structures.
