Abstract

Apparatus and systems for providing electrical energy to treat a tissue condition includes a high voltage pulse generator (300) for generating short high voltage pulses of energy and a delivery device (100, 700) for receiving the pulses of energy. The delivery device includes at least a pair of needle electrodes (104, 105) for penetrating into the tissue and delivering the pulses of energy to the tissue.
