Methods and devices using magnetic force to form an anastomosis between hollow bodies
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;
securing a second anastomotic component to the second vessel; and
using magnetic force to create an anastomosis between the first and second vessels with the first anastomotic component contacting the second anastomotic component.

Abstract
Methods and devices for forming an anastomosis between hollow bodies utilizes 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 be 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.
