    摘要: A surgical instrument, such as an electrical ablation device, includes an elongate member having therealong disposed a first electrode extending along an axis. A first expandable portion extends along the axis and defines a first perimeter of the first electrode and has an associated first diameter with respect to the axis. The first expandable portion includes a first framework selectively expandable to transition the first expandable portion from a contracted state to an expanded state. The first framework is selectively contractible to transition the first expandable portion from the expanded state to the contracted state. When the first framework is expanded, the first diameter is expanded and the first expandable portion is transitioned from the contracted state to the expanded state. When the first framework is contracted, the first diameter is contracted and the first expandable portion is transitioned from the expanded state to the contracted state.

    摘要: A device for guiding electrodes relative to a tissue treatment region. The device can comprise a body have a plurality of passages therethrough. Each passage can axially restrain an electrode positioned therein. When each electrode is axially restrained in a passage, the distal ends of the electrodes can be spaced a predetermined distance apart. Further, the electrodes can be held in a parallel or substantially parallel alignment when axially retained in the passages. The predetermined distance between the electrodes can correspond to a treatment distance in a tissue treatment region and the distal ends of the electrodes can be operably structured to conduct current therebetween when at least one of electrodes is energized by an energy source.

    摘要: An apparatus for treating tissue in a tissue treatment region. The apparatus can comprise an electrode ring having an interior perimeter and an electrode probe having a proximal end and a distal end. The distal end of the electrode probe can be structured to axially translate relative to the interior perimeter of the electrode ring. The electrode ring and the electrode probe can be operably structured to conduct current therebetween when at least one of the electrode ring and the electrode probe is energized by an energy source. Further, the energy source can be a Radio Frequency (RF) energy source, a pulsed energy source, an irreversible electroporation energy source, or a pulsed irreversible electroporation energy source. A current from the energy source can be selected to non-thermally ablate tissue in the tissue treatment region.
