Abstract
The present invention relates to a portable, hand held, self-contained cryosurgical probe system. In particular, the present invention relates to an improved portable, hand held cryosurgical probe system having easily changeable probes and cryogen sources wherein the cryogen can be provided in precharged cylinders mountable on the hand held unit and/or supplied from remote sources and which is capable of serving a plurality of probes via a multiprobe adapter. The present invention provides the flexibility of easily changeable probes and cryogen sources in a lightweight hand unit whereby different cryogens may be employed at different stages within a procedure or the cryogens may be mixed to vary the effective freeze capacity of the device.
