One of my designs, which has since gone into production multiple times, is a wart remover. It removes warts and other alien cells from the body -- and very effectively. It obliterates them -- sometimes one can hear the cells rupturing. It does this with low voltage (about 20V) high frequency (about 20kHz) electric pulses. But so far, this has only been applied externally. My guess is that it will work internally. For example, if one should have a diseased pancreas, with only an incision one may apply similar pulses to the pancreas, to remove alien cells. I have a design on my blog: the Wart Zapper.
