Abstract
A general purpose implantable radiotherapy device for delivering a predetermined dose of radiation in a predetermined radiation pattern. The device includes a biocompatible template adapted for implantation at a treatment site in a patient, and one or more radiation sources which are incorporated directly into at least a portion of the template, preferably by ion implantation methods. The shape of the radiation pattern from the device is determined at least in part by the location and distribution of the radiation source or sources incorporated into the template, and not solely by the shape of the template. The device is suitable for a wide variety of radiotherapy applications.
