ABSTRACT:
It is well known that radiation therapy can reduce the proliferation of rapidly growing cancer cells is a malignant tumor. The present invention utilizes a radioisotope which is integral to a stent which can irradiate the tissue in close proximity to the implantation site of the stent in order to reduce the rapid growth of malignant cells in a vessel, such as a bile duct while simultaneously maintaining vessel patency. The radioisotope could be place inside the stent, alloyed into the metal from which the stent is made, or preferably, it can be coated onto the stent's exterior surface.
