ABSTRACT:
A method and apparatus for sclerosing tissue located within an organ, e.g., the gall bladder, of a living being. The apparatus comprises a catheter having a rotatable working head at its distal end. The working head includes an extendable tissue engaging member. The catheter is introduced percutaneously through an introducer sleeve so that the working head is located within the organ. The extendable member is extended generally outward radially when the working head is rotated at a high rate of speed to cause its free end to repeatedly engage the tissue forming an inner surface of the organ to thereby mechanically scrape that tissue. A sclerosing agent, e.g., alcohol, may also be introduced into the organ to expedite the procedure.
