Magnetism in medicine

The authors have developed prostheses and methods whereby energy stored in magnetic fields and/or thermal energy can be utilized to restore function to organs which depend on movement of smooth, skeletal, or cardiac muscle, and whose function has failed because of failure of muscle movement. Such organs include the bladder, urinary sphincter, colostomy or ileostomy stoma, and levator palpebrae of the lid and heart. For additional details see Digests of the 1972 Intermag Conference (available from IEEE Headquarters).
