A closed loop cryosurgical system utilizing a plurality of cryoprobes to perform a cryosurgical treatment. The cryoprobes individually connect to a manifold portion of the cryosurgical system with a quick-connect coupling. Each cryoprobe includes a flexible conduit portion that is vacuum insulated leaving a freeze length of a probe end portion exposed on which ice ball formation may occur. The insulation space may be evacuated through an insulation channel by one or more of a getter chamber located within the cryostat, a vacuum pump located within the console, or by activation of one of the console compressors to pull the gases out of the insulation space prior to introduction of refrigerant into the circuit. The fluid pathways through which refrigerant travels through the console, cryostat, couplers, and cryoprobes can also be evacuated prior to a cryosurgical procedure.
