Abstract: A size-variable intrauterine pessary for adapting to the uterine cavity geometry, which has a rod part with flexible side arms and made from plastic, a coil, more particularly of copper, being optionally wound around the rod part, which has a fastening device for a thread and in which fitting takes place directly in the uterine cavity and which is characterized in that the rod part comprises a body and a control cylinder, that the body is forcibly coupled with the control cylinder, that through the forcible coupling the control cylinder can be moved against the body in the direction of its longitudinal axis and that the rod part has a coupling part into which snaps a fitting device during fitting and said device can be removed again after fitting.By turning the control cylinder following insertion, the spreading apart of the side arms can be adapted in random manner to the uterine cavity geometry.

Abstract: A ligator is provided for pinching off hemorrhoids and similar body tissues, comprising, in combination, a tubular housing; a suction tube fixedly mounted on the housing; and an actuator sleeve slidably mounted for reciprocable movement within the housing along the suction tube; a suction cup defining an open suction cavity facing outwardly and fixedly attached to and in flow communication with the suction tube for sucking a hemorrhoid into the suction cavity, the suction cup having means for receiving an elastic ring about the periphery of the open suction cavity; and means for ejecting said ring from the cup and onto the body portion link of a hemorrhoid sucked into the suction cavity and projecting from the cavity; said ejecting means being movable by reciprocation of the actuator tube between nonactuated passive and actuated ring-ejecting positions.
