  • Rectal hemorrhoid therapeutic apparatus
    Patent number: 4638806
    Abstract: The invention comprehends a novel, adjustable, flexible inserter head having a double lumen fluid feed via a hand pump from a reservoir means. The invention includes spring means to protect the outlet of fluid from collapse of the head cover by disposition over an internal outlet rod through which the cryogenic fluid exits to the reservoir. The stationary rod can be replaced so as to shorten the inserter and vary the original extended, slim head cover to a blunter, stouter configuration.
