Radioactive medical devices for inhibiting a hyperplastic response and method of making radioactive medical devices

Abstract

This invention involves radioactive medical devices for inhibiting an undesirable hyperplastic response in biological tissue, and a method for making the radioactive medical devices. In a preferred embodiment, a medical device for inhibiting a hyperplastic response in biological tissue generally comprises polymeric hydrocarbon molecules forming the medical device and a salt or an acid of a radioactive isotope occluded within the polymeric hydrocarbon molecules. Also in a preferred embodiment, a method of creating a medical device according to the present invention comprises: providing a first solvent in a container; introducing a salt or an acid of a radioactive isotope into the first solvent; introducing a second solvent into the first solution so as to form a second solution; and introducing the medical device into the second solution, wherein the ionic components of the radioactive isotope migrate into the molecular structure of the medical device.
