Abstract
This invention is a radioisotope impregnated material sheet or mesh designed to be placed between internal body tissues to prevent the formation of post-operative adhesions, which adhesions are really scar tissue formation. This mesh or gauze into which the isotope is placed may be either a permanent implant or it may be biodegradable. By impregnating an existing product such as the Johnson & Johnson SURGICEL.TM. absorbable hemostat gauze-like sheet with a beta emitting radioisotope such as phosphorous-32 with has a relatively short effective range of approximately 4 mm, the biodegradable mesh would act as a barrier to cell proliferation and hence be a deterrent to the formation of adhesions.
