ABSTRACT:
Systems and methods are provided for ablating tissue by implanting a plurality of electrode devices within the tissue to be treated and exposing the implanted electrode devices with RF energy conveyed from a separate electrode device. In this manner, a greater region of tissue is ablated than what would normally be ablated with the separate electrode device. In addition, the implanted electrode devices can create a roadmap that allows the progress of the treatment to be managed during follow-ups. The implanted electrode devices can be variously delivered to the tissue, for example, by detaching the electrode devices from one or more delivery devices. For example, a core wire with an electrolytically detachable junction can be used to separate the electrode device from the core wire. Pusher rods with mechanically detachable junctions are also contemplated.
