Abstract

See full text

A method and apparatus for intravascular radiotherapy for prevention of stenosis following angioplasty or other trauma to coronary arteries caused by smooth muscle cell hyperplasia in which a uniform dosage of radiation is delivered to the walls of the artery by positively positioning a radioactive source at the radial center of the artery being treated.
