Abstract
Energy delivery systems and methods are provided for use in biological tissue. The energy delivery system includes an energy source and an electrode array. The electrode array includes bipolar electrodes positioned so a first spacing between a pair of adjacent electrodes is different relative to a second spacing between at least one other pair of adjacent electrodes. The electrode array and the energy source are coupled and configured to generate uniform energy density in target tissue according to impedance of the target tissue.

A system comprising:
- an energy source;
- and
- an electrode array comprising bipolar electrodes positioned so a first spacing between a pair of adjacent electrodes is different relative to a second spacing between at least one other pair of adjacent electrodes, wherein the electrode array and the energy source are coupled and configured to generate uniform energy density in target tissue in response to impedance of the target tissue.
