Abstract
An expandable, flexible multi-tubular cryoprobe operational with a near critical cryogenic working fluid. The inlet fluid transfer micro-tubes utilized are formed of material that maintains flexibility in a full range of temperatures from −200° C. to ambient temperature. During operation, the cryoprobe is mechanically actuated to provide radial expansion of the inlet fluid transfer micro-tubes. Thus, enhanced thermal contact with target biological tissue to be treated is provided.
