The PEAK™ technology offers an alternative to standard RF surgical techniques for tissue cutting and coagulation. Our technology operates in a regime of short-pulsed plasma-mediated electrical discharges. This technology limits heat diffusion and associated thermal damage to sub-cellular dimensions. In contrast, most commercially available RF-based surgical products use continuous voltage waveforms to cut tissue, which leads to significant heat diffusion into adjacent tissues and results in undesirable collateral damage.

So, apparently this small technology I’ve been including in the intro section of many of my papers just got another hefty boost from investors.

According to this and this articles they just got another $21 mil.

Very nifty toy this is, and definitely something to watch out for quite soon at a hospital.  They seem to be shying away from “plasma” a little though as far as I know the technology is actually mainly based on plasma.  I think I need to go read about this in further detail.  In the mean time, here’s another quote:

The technology, however, originated at Stanford, where PEAK, it turns out, stands for “pulsed electron-avalanche knife.” The technique, developed by a team led by Daniel Palanker, involves using a high voltage electric field to create a plasma, a kind of electrically charged gas, which can be shaped and controlled to make clean cuts in tissue.
