PathFormer is an electrosurgical hand-held medical device that cuts holes in nails and skin. It employs the mesoscissioning technology, cutting the nail/skin with a microcutting tool, using skin electrical impedance as a feedback for stopping the cutting intervention to eliminate sensation.

Path Scientific has received 510(k) clearance from the U.S. Food and Drug Administration (FDA) to market PathFormer for creating holes in nails for relieving (and preventing) the pain of subungual hematoma (black toe).
