Methods for forming anastomoses using magnetic force
First Claim
1. A method for forming an anastomosis between first and second vessels using magnetic force, the method comprising steps of:
- selecting a first vessel having a lumen;
selecting a second vessel having a lumen;
securing a first anastomotic component to the first vessel to define a first contact surface, the first contact surface being formed at least in part by an exposed portion of the first anastomotic component;
securing a second anastomotic component to the second vessel to define a second contact surface; and
using magnetic force to create an anastomosis between the first and second vessels by contacting the exposed portion of the first contact surface with the second contact surface.

Abstract
Methods and devices for forming an anastomosis between hollow bodies using magnetic force to couple anastomotic securing components and create a fluid-tight connection between the lumens of the hollow bodies. End-to-side, side-to-side and end-to-end anastomoses can be created without using suture or any other type of mechanical fasteners, although any such attachment means may be used in conjunction with the magnetic attachment The securing components have magnetic, ferromagnetic or electromagnetic properties and may include one or more materials, for example, magnetic and nonmagnetic materials arranged in a laminated structure. The system of anastomotic securing components may he used in many different applications including the treatment of cardiovascular disease, peripheral vascular disease, forming AV shunts for dialysis patients, etc., and may be sized and configured for forming an anastomosis to a specific hollow body, for example, a coronary artery or the aorta.

17. A method for forming an anastomosis between first and second vessels using magnetic force, the method comprising steps of:
-
selecting a first vessel having a lumen, selecting a second vessel having a lumen;
securing a first anastomotic component to the first vessel by capturing tissue of the first vessel between two portions of the first anastomotic component that respectively contact an intimal surface and an exterior surface of the first vessel, wherein the first anastomotic component is secured to the first vessel by compressing the tissue of the first vessel between the two portions of the component, the two portions of the first anastomotic component compressing the intimal and exterior surfaces of the first vessel as a result of magnetic force;
securing a second anastomotic component to the second vessel; and
using magnetic force between the first and second components to create an anastomosis that places the lumens of the first and second vessels in communication. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35)

36. A method for forming an anastomosis between first and second vessels using magnetic force, the method comprising steps of:
-
selecting a first vessel having a side wall and a lumen;
selecting a second vessel having a side wall and a lumen;
securing a first anastomotic component to the first vessel by magnetic force;
securing a second anastomotic component to the second vessel by a non-magnetic attachment; and
using magnetic force between the first and second anastomotic components to create an anastomosis that places the lumens of the first and second vessels in communication;
wherein the magnetic force between the first and second anastomotic components is sufficient to maintain the anastomosis between the first and second vessels without interconnecting the first and second anastomotic components. - View Dependent Claims (37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49)

50. A method for forming an anastomosis between first and second vessels using magnetic force, the method comprising steps of:
-
selecting a first vessel having a lumen;
selecting a second vessel having a lumen;
securing a first anastomotic component to the first vessel by capturing tissue of the first vessel between two portions of the first anastomotic component, the two portions of the first anastomotic component respectively contacting an intimal surface and an exterior surface of the first vessel;
securing a second anastomotic component to the second vessel, the second anastomotic component being secured to the second vessel without contacting an intimal surface of the second vessel; and
using magnetic force to create an anastomosis that places the lumens of the first and second vessels in communication. - View Dependent Claims (51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65)
