  • Publication number: 20140039491
    Abstract: 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.

  • Publication number: 20140031813
    Abstract: 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.

  • Publication number: 20140012247
    Abstract: 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.

  • Patent number: 8603078
    Abstract: Methods and devices are provided for allowing a surgical instrument to be supported by a surgical support system configured to controllably guide the instrument to a desired position at surgical site. A surgical support system is provided that includes a guide port defining a pivot point about which a surgical instrument advance therethrough can pivot. The guide port, and hence the pivot point, can be located a distance above a tissue surface through which the instrument is advanced. Methods and devices are also provided for allowing insufflation of a body cavity without introduction of an insufflation fluid therein. A mechanical insufflation device is provided that includes an expandable distal member configured to selectively expand and unexpand to mechanically insufflate a body cavity. The mechanical insufflation device can optionally be used with the surgical support system.

  • Patent number: 8491526
    Abstract: A surgical device comprises a housing, a bioprocessing module, an end effector, and a pumping device. The bioprocessing module comprises media reservoirs, fluid conduits in communication with the reservoirs, and a port through which media is expelled. The end effector is configured for insertion into a lumen and delivering a tissue repair composition into that lumen. The end effector has at least one fluid conduit extending therethrough and at least one orifice in communication with the fluid conduit. The fluid conduit in the first end effector is in fluid communication with the port on the bioprocessing module. The pumping device is operable to urge a tissue repair composition comprising at least a portion of the contents of the media reservoirs through the fluid conduit of the first end effector such that the tissue repair composition is expelled from the at least one orifice.
