Patent ID: 7604632

Claim:
A cryosurgery device for use with an aerosol container having a valve and a valve stem extending outwardly from the valve and the container, the container holding a refrigerant therein, the cryosurgery device comprising: an actuator adapted to seat on a stem of a container in order to depress the valve stem and release refrigerant from the container, the actuator including an outlet tube for receiving the released refrigerant from the container; an inlet tube adapted to receive the valve stem therein; and a main body which connects together said inlet tube and said outlet tube in fluid communication with each other, the main body including an arrangement for limiting insertion of the valve stem into the inlet tube, said main body further including a generally cylindrical side wall, a bottom wall which closes the side wall and which includes an opening, with the inlet tube and outlet tube being connected to opposite sides of the bottom wall in surrounding relation to the opening therein, and a ledge connected with an upper edge of the side wall, the ledge defining an actuating surface against which at least one key engages, such that application of said pressure to the actuating surface causes said actuator to move such that the shoulder engages and depresses the valve stem to release the refrigerant; a hub adapted to mount on the container, the hub including at least one opening therein and a first aligning arrangement; an applicator tube mounted to the hub in fluid communication with the outlet tube of the actuator; a porous tip mounted to a distal end of the applicator tube for receiving the refrigerant; and a base having a central opening for receiving the hub and applicator tube therein, the base including at least one key and a second aligning arrangement for cooperating with said first aligning arrangement such that the at least one key can enter the at least one opening in the hub to engage and apply pressure to the actuator to cause the actuator to depress the stem and release the refrigerant.
