A surgical cryoablation system comprising a valve having a valve inlet and a valve outlet the valve inlet connectable to a source of cryogenic fluid at a pressure of greater than 4000 psi and the valve outlet connectable to a cryoablation probe, such that the valve outlet is in fluid communication with the cryoprobe such that the source of cryogenic fluid is in fluid communication with the valve inlet.一種手術低溫消融系統包括一閥，該閥具有一閥入口及一閥出口，該閥入口可連接至處於大於4000 psi之一壓力下的一低溫流體源且該閥出口可連接至一低溫消融探針，使得該閥出口與該低溫探針流體連通，使得該低溫流體源與該閥入口流體連通。
