Abstract
Abstract A method of destroying tissue such as a gall bladder located within the body of a living. A sclerosing agent is introduced into the body in a volume contiguous with the surface of the tissue to be destroyed. The sclerosing agent comprises a flowable material made up of a liquid carrier and a large plurality of abrasive particles, e.g., acicular particles of carborundum, silicon carbide, etc., Optionally, a symphysis agent, such as an antibiotic, may be introduced into the volume. Once the agent is introduced, it is caused to circulate therein whereupon its scrapes across the surface of the tissue to effect the sclerosing thereof.
