Cryoprobe

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 endof 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 communicationwith the fluid exhaust conduit, the flow restricting element regulating the flow of fluid through at least a portion of the fluid exhaust conduit. 公开了一种冷冻外科装置，诸如冷冻外科探针（冷冻探针）。一些示例性实施例可包括：细长轴，该细长轴至少部分地容纳或界定流体供应导管和流体排出导管，该细长轴包括终止于封闭远端处的远侧消融区段；壳体，其至少部分地环绕细长轴的近端的至少一部分，并接收或界定流体供应导管的至少一部分和流体排出导管的一部分；和/或与流体排出导管流体连通的流量限制元件，流量限制元件调节通过流体排出导管的至少一部分的流体流动。
