Abstract
The present invention is directed to bipolar ablation systems. A bipolar electrode system for ablation therapy is disclosed, including a pressure-sensitive conducting composite layer and a pair of electrodes in electrical conductive contact or communication with the pressure-sensitive conducting composite layer. Energy (e.g., ablation energy) is delivered via the pressure-sensitive conductive composition when sufficient pressure is applied to transform the pressure-sensitive conductive composite to an electrical conductor. An electrically insulative flexible layer, which may include a passageway for a fill material is also disclosed. In some embodiments, the systems can also be used for targeted delivery of compounds, such as drugs, using a bipolar electrode.
