Abstract

Apparatus is provided for the localised heating of internal body tissue to prevent unwanted freezing of healthy tissue adjacent to a site of cryogenic surgery. The apparatus has a bag locatable adjacent the tissue which provides for the entry of liquid at a required temperature, circulation of liquid through the bag in a heat transfer relation with a wall thereof, and removal of the liquid. In one embodiment the bag is provided around an outer wall of a catheter and in fluid communication with catheter contents.
