Abstract
Abstract A low-energy, nonabsorbable radioactive seed patch method and apparatus for use in conjunction with surgical procedures for prevention of reoccurrence of carcinoma and other type tumors. The patch is a nonabsorbable, plastic mesh with iodine-125 seeds threaded therein according to a predetermined pattern. The mesh with seeds threaded therein is then embedded in a nonabsorbable silicone forming the completed patch. The patch is permanently implanted over the area of potential residual cancer following surgery.
