Abstract:
1. A method of forming a low-dose (LDR) brachytherapy device, the method comprising: forming a plurality of substrates having a water-insoluble form of a radioactive material thereon; and positioning the plurality of substrates on a carrier core; and forming a medical device from the carrier core and the plurality of substrates, wherein forming the plurality of substrates having the water-insoluble form of the radioactive material thereon comprises: depositing a solution comprising a soluble form of a radioactive material on a substrate; and converting the soluble form of the radioactive material to a water-insoluble form of the radioactive material on the substrate, and wherein converting the soluble form of the radioactive material to a water insoluble form of the radioactive material comprises exposing the substrate and the water-soluble form of the radioactive material to plasma thereby decomposing the soluble form of the radioactive material to a water-insoluble form of the radioactive material.
