Abstract: An energy delivery device for treating a patient includes a probe body and a plurality of elongate electrode elements that extend radially away from the probe body when deployed into tissue of the patient. The electrode elements are adapted to receive electrical treatment energy such as irreversible electroporation (IRE) pulses from an energy source. In one embodiment, each electrode element has a longitudinally varying electrical resistance at the electrode-tissue interface along the electrode so as to provide a uniform electric field along the length of the electrode. The uniform electric field allows a more uniform ablation of tissue within a treatment zone.

Abstract: Devices and methods for ablating a selected tissue volume, such as for ablating tumor, are disclosed. In certain embodiments, the ablation devices include a low-conductivity, tissue-piercing tip, an adjustment mechanism for selectively adjusting the length of an exposed portion of the electrode, for producing ablation volumes of desired geometry. In other embodiment, the methods allow the adjustment of the length of the exposed electrode portion be carried out by moving an insulative sleeve along the electrode.

Abstract: A device for controlling electromagnetic radiation emitted by a structure is described. The device has a reactive element comprising an array of conductors disposed on a dielectric surface such that the displacement between a conductor and any other conductor adjacent to it is small compared to the wavelength of the electromagnetic radiation. As such, the array of conductors represents an effectively continuous conductive surface to the electromagnetic radiation and the surface impedance of the conductive surface (2) is reactive.

Abstract: Ablation devices and associated methods are provided for use in palliative treatment of a bone tumor on or in a compact bone region. The bone treatment devices include an elongate probe having a distal end. A proximal end of the probe supports placement in a location at or adjacent to the bone tumor. Electrodes are carried within the probe for deployment from the distal end into the bone tumor. The electrodes may be shapable to create, upon deployment, an array of electrodes that defines a geometric area within the bone tumor. Application of energy, for example energy from a radio frequency (RF) source, to the area of the bone tumor via the electrodes destroys at least a portion of the nerve receptors located in or adjacent to the tumor and produces a reduction in pain associated with the bone tumor. Liquid, such as a polymer in liquid form, may be injected through an electrode needle, with electrode heating being employed to allow introduction of the polymer solution through the needle and/or hardening at the site of injection.
