More Information
Summary:An electrosurgical end effector for ablating tissue is provided that comprises at least one elecfrically-conductive ablation member adapted to be connected to a source of RF energy, with the ablation member having a tissue engaging surface and defining an internal fluid passageway. Preferably, the end effector includes two electrically conductive ablation members that are electrically isolated from one another and have their fluid passageways in fluid communication. Alternatively, the end effector may comprise four electrically conductive ablation members arranged as two pairs of ablation members, all of the ablation members having internal fluid passageways that are electrically isolated from each other, with the fluid passageways of each of the four ablation members being in fluid communication with each other.'
