Robert William Goddard, Leslie John Penny: Cryosurgical instrument. Spembly Medical, Renner Otto Boisselle & Sklar P L L, January 19, 1999: US05860970 (55 worldwide citation)

A cryosurgical instrument comprises a metal cooling tip operable to be cooled by a flow of cryogenic fluid within the tip, at least a boiling region of the tip being coated with a heat-insulating coating. The presence of the heat-insulating coating can promote nucleate boiling of the fluid rather th ...

A cryosurgical probe. Spembly, September 22, 1982: GB2094636-A (37 worldwide citation)

A cryosurgical probe having a tip portion E designed to control iceball formation and thus the freezing efficiency of the probe. The probe operates by the Joule-Thompson effect of gas cooling when expanded through a restriction J. In known probes, after cooling in this way, the gas is immediately ve ...
