CoreTherm^® treatment employs a patented intra-prostatic temperature probe that measures actual tissue temperatures at three locations within the prostate. Prostate volume is reduced by heating and coagulation action caused by microwaves emitted from the antenna.

During treatment, the temperatures in the prostate, the changes in the intra-prostatic blood flow and the tissue destruction through calculated cell kill are monitored in real-time.

The easy to use software system also measures other bodily temperatures for added safety, such as the rectal temperature and the temperature at the penile-scrotal angle as part of the extensive safety system. The device automatically turns off if these temperatures exceed the safety settings.
