Abstract
A closed-loop system for cryosurgery includes a cryofluid at cryogenic temperatures flowing through a closed-loop flow path. A pump, configured for operating at cryogenic temperatures, circulates the cryofluid in the closed-loop flow path. The closed-loop flow path includes a heat exchanger coupled to a heat sink configured for cooling the cryofluid in the closed-loop flow path to cryogenic temperatures. The closed-loop system includes one or more cryoneedles configured for providing cryotherapy, and one or more flow control devices, wherein each flow control device is configured for operating at cryogenic temperature and for selectively flow connecting or flow disconnecting at least one of the cryoneedles to the closed-loop flow path.
