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.

L'invention a trait à un appareil amélioré destiné à fournir un fluide de cryochirurgie dans un environnement chirurgical ou un autre environnement médical. L'appareil préféré comprend un conduit en polytétrafluoroéthylène expansé multicouche, qui présente des dimensions réduites, une faible conductivité thermique, et une souplesse exceptionnelle. Une large gamme d'instruments de traitement peuvent être reliés à l'extrémité du conduit, afin que soient administrés des traitements médicaux allant de l'application topique directe d'un fluide de cryochirurgie à des utilisations chirurgicales ou endochirurgicales en circuit fermé.
