Problems solved by technology

Often, the tissue proximate to the probe heats up faster than tissue farther away from the probe, which may limit the size of the lesion.
In addition to limited lesion size, prior art devices typically form lesions with minimal extension distal to the tip of the electrode, as described by Bogduk et al.

Embodiment Construction

[0027] Embodiments of the invention described herein provide devices, systems, and methods which address some or all of the deficiencies of the current state of the art as described above. For example, in one broad aspect, embodiments of a device of the present invention may comprise an elongate member having one or more electrically insulated portions, and a distal face comprising one or more electrically exposed conductive portions for delivering energy substantially distal to the elongate member. At least one of the one or more electrically insulated portions may extend from a proximal region of the elongate member to the distal face.

[0028] In another broad aspect, a method is provided for creating a lesion at a target site within a body of a human or animal using an electrosurgical device. The method may comprise the steps of: inserting the electrosurgical device into the body such that the electrosurgical device is generally upstanding relative to the target site; and delivering

Abstract

A method and apparatus are disclosed for delivering energy substantially distal to an electrosurgical device. Embodiments of a device of the present invention may comprise an elongate member having one or more electrically insulated portions and a distal face comprising one or more electrically exposed conductive portions for delivering energy substantially distal to the elongate member. At least one of the one or more electrically insulated portions may extend from a proximal region of the elongate member to a distal end of the elongate member. In addition, a method is provided for creating a lesion at a target site within a body of a human or animal using an electrosurgical device. The method may comprise the steps of: inserting the electrosurgical device into the body such that the electrosurgical device is generally upstanding relative to the target site; and delivering energy from an energy source through a distal face of the electrosurgical device such that the energy is directed substantially distal to the distal face towards the target site.
