A surgical tool and method of surgical treatment involving a radio frequency source (e.g. 13.0 to 28.0 MHz) creating an electromagnetic field in the vicinity of tissue to be surgically treated and a grounded, tuned, electromagnetic field focusing probe (22) that focuses the electromagnetic field energy at the tip (20) of the probe, thus instanteously vaporizing, cutting and cauterizing the tissue in contact with the probe tip. Such a surgical tool is capable of creating a virtually bloodless, micro-thin incision as well as selectively coagulating body fluids (e.g., blood) and as such, in particularly useful in neuro, oncological and vascular surgery. |
