Abstract: A sterile disposable bipolar ablation needle (the needle) comprising an exposed outer electrode and an inner electrode is described. The needle can also include an insulating layer disposed between the inner electrode and the outer electrode. The needle can further include a first exposed region of the needle disposed near a proximate end of the needle, the first exposed region including a first exposed portion of the inner electrode and a first exposed portion of the outer electrode, the first exposed region constructed to provide contact to a connector, and a second exposed region of the needle disposed near a distal end of the needle. A stylet can be provided for use with the needle and a sterile cover can be provided to cover the needle and maintain sterility of the needle and the stylet.

Abstract: Some implementations include a coaxial bipolar ablation instrument comprising an outer needle and an inner needle inserted into the outer needle. The instrument can also include a first insulating layer disposed between the inner needle and the outer needle, and a second insulating layer disposed over a portion of the outer needle. The instrument can further include a first exposed region of the instrument disposed near a proximate end of the instrument, the first exposed region including a first exposed portion of the inner needle and a first exposed portion of the outer needle, the first exposed region constructed to provide contact to a connector, and a second exposed region of the instrument disposed near a distal end of the instrument, the second exposed region forming the active region of the instrument and including a second exposed portion of the inner needle and a second exposed portion of the outer needle.

Abstract: An electrocautery instrument is disclosed comprising: a handle having a handle axis; a first electrode assembly, the first electrode assembly having a first handle electrode section retained in the handle, a first oblique electrode section extending from the handle, and a first ablation electrode section disposed at an offset distance from the handle axis; and a second electrode assembly, the second electrode assembly having a second handle electrode section retained in the handle, a second oblique electrode section extending from the handle, and a second ablation electrode section disposed at the offset distance from the handle axis, the second electrode assembly being generally congruent to the first electrode assembly, the handle being configured to retain the first ablation electrode section in generally parallel relationship to the second ablation electrode section.
