18 Claims

1. A medical device comprising a generator in electrical communication with a plurality of electrodes, wherein the generator is configured to deliver a pulse train of energy having a predetermined frequency and including a plurality of pulses, each pulse having a pulse width of between 1 μs and 15 μs, wherein the plurality of pulses includes a sequence of alternating positive pulses and negative pulses with an inter-phase delay after each positive pulse and before a subsequent negative pulse and with an inter-pulse delay after each negative pulse and before a subsequent positive pulse, wherein the inter-phase delay is less than the inter-pulse delay.
