Abstract

Cryosurgical devices, such as cryosurgical probes (cryoprobes) are disclosed. Some example embodiments may include an elongated shaft at least partially housing or delineating a fluid supply conduit and a fluid exhaust conduit, the elongated shaft including a distal ablation section terminating at a closed distal end, a housing at least partially circumscribing at least a portion of a proximal end of the elongated shaft and receiving or delineating at least a portion of the fluid supply conduit and a portion of the fluid exhaust conduit; and/or a flow restricting element in fluid communication with the fluid exhaust conduit, the flow restricting element regulating the flow of fluid through at least a portion of the fluid exhaust conduit.
