Abstract:
1. A cryosurgery system comprising: (a) an intervention module which comprises at least one cryoprobe operable to be inserted into the body of a patient and to cryoablate tissues therein; (b) an ablation border estimation module which uses information received from at least one of a group consisting of an imaging modality and a thermal sensor to estimate a border of an ablation volume within a body of a patient, said border estimation module being configured to: (c) a cryosurgery control module which calculates a command for said cryosurgery support module, said calculation being based at least in part on said estimated ablation volume border; (d) a cryosurgery support module configured to control delivery of a coolant fluid to a fluid supply conduit in response to commands received from said control module; and (e) a fluid supply conduit operable to deliver a coolant fluid from said support module to said cryoprobe.
