Microwaves in surgery: method and results

The design of novel devices using 2.45 GHz radiation to produce thick eschars for coagulation in the surgery of highly vascular organs is described. Twenty-two patients have been treated to date in FDA clinical trials: results in ten cases at Baystate Medical Center in Springfield, MA are detailed. Medically, the particular advantage offered by the microwave system described here is that it provides coagulation in depth. It offers significant advantages in the surgery of large, highly vascular organs and other regions in which dangerous hemorrhaging can occur, or in trauma situations in which the coagulating power of the microwave devices is required.<>
