Abstract:
1. A tissue ablation device, comprising: an array of bipolar electrodes configured to be coupled to an energy source, wherein the array of bipolar electrodes comprises at least one electrode forming a semi-spherical electrode in a deployed state, wherein the at least one electrode comprises a first portion having a first polarity and a second portion having a second polarity that is different from the first polarity, wherein the first portion is coupled to the second portion by extending through an insulative member to form the semi-spherical electrode when deployed; wherein the array of bipolar electrodes is configured to at least partially encircle a portion of an intended ablation that will at least partially encompass a target tissue and create an ablation pattern around a tissue volume including the target tissue, and ablate the target tissue from an outside surface of the target tissue to an inner portion of the target tissue when the array of bipolar electrodes is energized by the energy source.
