The cryosurgical probes
being developed today utilize either a single-stage or a two-stage mixed gas Joule-Thomson cycle.
This paper describes a computational model of a two-stage JT cycle for use in a cryosurgical probe.
Therefore, a numerical optimization technique described here is used to design an optimized cryosurgical probe that achieves the maximum cooling per heat exchanger size.
today announced that SurgiFrost(TM), a cryosurgical probe
to treat cardiac arrhythmias, has been used successfully on the first five (5) patients.
As well, it is also involved in the co-development and commercialization of the SurgiFrost(TM) cryosurgical probe
to treat AF.
Although not approved for prostate cancer treatment, the UROSProbe has the potential to allow the precise visualization of both the prostate and the cryosurgical probe
with ultrasound, using a proprietary "chip at the tip" as a navigational beacon.
Cryotherapy involves the placement of cryosurgical probes
into the prostate to freeze and destroy the tumor.
