Methods and devices for forming an anastomosis between hollow bodies utilize magnetic force to join anastomotic elements (360, 362) and connect the hollow body lumens. End-to-side anastomosis, side-to-side anastomosis, and end-to-end anastomosis can be made with or without mechanical connections between elements (360, 362). Fixed elements (360, 362) have the ability to generate a magnetic field and may include materials or assemblies. An element (278, 280) may also be used to form a port to the lumen of the blood vessel, which element (278, 280) is attached to the blood vessel by mechanical and / or magnetic means. The magnetic elements (278, 280) may comprise means (282, 284) for enhancing the fixation of the anastomosis by concentrating the magnetic flux between the respective elements (278, 280) and increasing the attractive force.
