Abstract
A tissue treatment apparatus is described that includes a housing having a proximal end and a distal end including a tissue contacting surface having a plurality of apertures. The housing defines an interior. An electrode array is positionable in the housing interior. The electrode array includes a plurality of bipolar electrodes. The electrode array is configured to be advanced from the housing interior so a first spacing between a deployed pair of electrodes of the plurality of electrodes is different relative to a second spacing between at least one other deployed pair of electrodes. An advancement device is configured to selectively advance the plurality of electrodes from the housing interior into a target tissue site and withdraw advanced electrodes into the housing interior.
