Abstract
Methods and apparatuses for applying energy to a target tissue or cell are described herein. These methods and apparatuses may use one or more pairs of stimulating electrodes and a dedicated ground electrode to locally apply energy to a target tissue or cell at or adjacent the dedicated ground electrode.
Claims28
A method of applying energy to a target tissue or cell, the method comprising:
- positioning a targeting electrode on or adjacent to the target tissue or cell;
- applying a first train of sub-microsecond unipolar pulses from a first electrode and a second train of sub-microsecond unipolar pulses from a second electrode,
- wherein the first and second trains of sub-microsecond unipolar pulses are concurrently applied and are out of phase so that the first and second trains of sub-microsecond unipolar pulses sum at the target tissue or cell.

A system for applying energy to a target tissue or cell, the system comprising:
- a first output configured to couple to a first one or more electrode(s);
- a second output configured to couple to a second one or more electrode(s);
- a third output configured to couple to a targeting electrode;
- a pulse generator configured to generate a first train of sub-microsecond unipolar pulses and a second train of sub-microsecond unipolar pulses, wherein the first and the second trains of sub-microsecond unipolar pulses are 180 degrees out of phase;
- and
- a controller configured to apply the first train of sub-microsecond unipolar pulses to the first output concurrently with the second train of sub-microsecond unipolar pulses to the second output, and to couple the third output to the targeting electrode.
