Abstract
A high-energy density magnetic particulate is mixed with a biocompatible material to form a composite. The composite may be formed into a sheet, which may be rolled into a tube and laser-cut to form at least one medical device, such as one piece of a multi-piece anastomosis device. The device includes a number of interconnected struts, which may be sized such that any portion of the member placed in the bloodstream is substantially non-thrombogenic. A magnetic field is induced in the composite.
