摘要： A catheter (12) for the positioning of a radioactive material (24) for therapeutic radiation treatment of the body is disclosed. The catheter includes a radioactive source (24) positioned at the distal end thereof and is sufficiently flexible and strong to navigate in the body to the desired treatment location. The radioactive source may be provided to the catheter in an number of different ways. In one set of embodiments, the radioactive source is bonded to the inner or outer surface of the catheter body (46), a catheter attachment (10) or a carrier positionable within the body.

摘要： Radiation delivery devices (13b) useful in brachytherapy which employ radioactive palladium-103 as the radiation source material (10a) are disclosed. Certain embodiments of the disclosed radiation delivery devices (10) have the advantages that they can be fabricated with the desired specific activity, that the self-shielding effects of the devices are minimized, that the radioactive source material (10a) is bonded to a substrate in a manner which substantially prevents it from becoming detached, and that a variety of customizable radiation delivery devices can be made using the concepts of the invention.
