Methods, devices and systems for forming magnetic anastomoses
First Claim
1. A method for forming an anastomosis between first and second hollow bodies using magnetic force, the method comprising steps of:
- receiving first and second anastomotic components respectively configured to be secured to first and second hollow bodies, the first and second components being magnetically attracted to one another;
mounting the first component on a delivery device;
securing the second anastomotic component to the second hollow body;
mounting the second anastomotic component on the delivery device with the second hollow body secured to the second component;
securing the first anastomotic component to the first hollow body; and
using magnetism to couple the first and second anastomotic components and form an anastomosis between the first and second hollow bodies.

Abstract
Methods, devices and systems for forming magnetic anastomoses between two blood vessels. A first anastomotic component is removably supported by the distal end of a delivery device for attachment to a first vessel. The delivery device also supports a second anastomotic component that has been secured to a second blood vessel. The device is operated to secure the first component to the first vessel, couple the second component to the first component, and then release the components to complete the anastomosis. A robotic anastomosis system includes several robotic instruments that may be positioned through ports in a patient, used to secure an anastomotic component to a vessel, and then used to magnetically couple the components. Delivery devices for deploying magnetic anastomotic components include an actuator that uses magnetic repulsion to move the components into engagement with the inner and outer surfaces of the vessel wall. The anastomotic components are secured to the vessel wall by magnetic force and in addition may be secured by mechanical attachment.
