Title: Innovations by John L Russell, Jr.
Introduction
John L Russell, Jr. is a notable inventor based in Alpharetta, GA (US), recognized for his contributions to the field of brachytherapy. He holds a total of 8 patents, showcasing his innovative approach to medical technology.
Latest Patents
One of his latest patents involves the development of plastic brachytherapy sources. This invention provides an implantable source of therapeutic radiation encapsulated in a biocompatible plastic capsule, which is transparent to radiation. The capsule contains a radiation source made up of particles of a radioactive isotope, such as palladium, iodine, or cesium, suspended in a fluid carrier that solidifies at elevated temperatures. Additionally, the capsule features a marker and a socket for attaching spacers, allowing for the creation of linear strands and planar arrays of the capsules. The spacers can also serve functional purposes, such as generating heat or releasing medication.
Another significant patent by Russell focuses on radioisotope dispersion in a matrix for brachytherapy. This invention fabricates therapeutic sources from radioactive composites, combining a radioactive powder with a biocompatible polymeric matrix. The radioactive powder is dispersed randomly within the polymer, which can be manufactured in various forms, such as rods or films. This composite generates a uniform radiation field, and the polymer can be designed to dissolve or degrade in the body at a predetermined rate, depending on the half-life of the radioisotope used.
