Abstract: 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.

Abstract: A surface electrode for ablating tissue is provided. The surface electrode comprises a base, a plurality of tissue penetrating needle electrodes extending from the surface of the base an adjustable distance, and an electrical interface coupled to the plurality of needle electrodes. The adjustability of the needle electrodes allows the depth that the needle electrodes penetrate through tissue to be adjusted.

Abstract: A medical probe assembly and method are provided for ablating tissue. The probe assembly comprises an elongated shaft and an electrode array mechanically coupled to the distal end of the shaft. The electrode array is configured to assume an outwardly curved shape, when exposed to a first temperature, and assume a pointed tip when exposed to a second temperature less than the first temperature. The first temperature is preferably greater than body temperature, e.g., equal to the tissue ablation temperature, and the second temperature is preferably less than a tissue ablation temperature, e.g., body temperature. In this manner, the pointed tip assumed by the electrode array facilitates introduction of the probe assembly through the tissue prior to the ablation process, while the outwardly curved shape assumed by the electrode array facilitates deployment of the electrode array within the tissue during the ablation process.

Abstract: A medical probe assembly and method for ablating tissue using radio frequency energy is provided. Included in the medical probe assembly is an ablation probe and an alignment device. The alignment device comprises a surface and plurality of apertures through which the ablation probe can be guided into the target region of the patient. The apertures may be uniformly or non-uniformly spaced and parallel or non-parallel from each other. The apertures may be indexed from each other in a two dimensional plane. By adding one or more bosses or recesses to the apertures, the apertures may indexed from each other in a three dimensional space and provides an improved system and method for accurately creating compound lesions on tumors. Furthermore, by adding removable inserts to the recesses, the depth of the recess may be adjustable.
