An improved apparatus for delivery of cryosurgery fluid in a surgical or other medical environment is disclosed. The preferred apparatus comprises a multiple-layered expanded polytetrafluoroethylene conduit that has a low profile, has low thermal conductivity, and provides exceptional flexibility. A wide variety of treatment instrumentalities may be employed on the end of the conduit to provide medical treatments ranging from direct topical application of cryosurgery fluid to open or closed-system surgical or endosurgical uses.
