Abstract

Abstract A surgical fastening device, such as a suture, staple, clip, pin or the like, is rendered therapeutically radioactive in order to inhibit cellular proliferation at a wound or surgical repair site, by implantation of a radioisotope into the material of the device. The device can be made of any material, including metals, nonmetals, plastics and ceramics.
