Abstract
The invention is directed to a radiation source for delivery of a radiation treatment to a body lumen. The radioactive tip of the source wire is detachable from the main portion of the core wire to allow the radioactive source in the tip to be sterilized and re-sterilized independently of the core wire. The detachable radioactive tip also includes a flexible portion for improved tracking through a lumen of a catheter.
