  • Publication number: 20200078085
    Abstract: Aspects of the present disclosure are presented for a single surgical instrument configured to grasp, seal, and/or cut tissue through application of therapeutic energy, and also detect nerves through application of non-therapeutic electrical energy. A medical device may include two jaws at an end effector, used to apply therapeutic energy and to perform surgical procedures. The therapeutic energy may be in the form of ultrasonic vibrations or higher voltage electrosurgical energy. One of the jaws may be configured to cut tissue through application of the blade. In addition, one or both of the two jaws may be configured to apply nontherapeutic energy for nerve stimulation probing. The application of therapeutic energy may be disabled while the nontherapeutic nerve stimulation energy is applied, and vice versa. The nontherapeutic nerve stimulation energy may be applied to the use of one or more probes positioned near one or both of the jaws.

  • Patent number: 10492880
    Abstract: A surgical device for guiding electrodes into a tissue treatment region is disclosed. The surgical device includes electrodes configured to conduct current therebetween upon energizing at least one of the electrodes, a first body portion, and a second body portion. The first body portion and the second body portion are configured to operably form a first channel that extends along a first axis and a second channel that extends along a second axis. The surgical device further includes a predefined electrical ablation distance defined between the first axis and the second axis and a spring positioned between the first body portion and the second body portion. The spring is deformable between a first configuration and a second configuration, wherein the first channel is configured to open to receive one of the electrodes when the spring is in the first configuration. The first channel is configured to close and axially restrain the electrode received therein when the spring is in the second configuration.

  • Patent number: 10314649
    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: 20170340339
    Abstract: A bone cutting surgical instrument includes features to mitigate heat generation during use. Excessive heat can be detrimental to bone health as well as to the instrument itself. In one example a liquid dispensing feature provides a flow of cooling liquid to an ultrasonic blade via a lumen in a waveguide of the instrument. In another example, the blade has a serrated edge with a plurality of teeth arranged in a pattern to provide dimension and space during cutting actions. In another example, the blade has an oversize distal portion that creates an oversize slot when cutting to avoid excessive contact between the cut bone and proximal portions of the blade. In another example the blade includes an irrigation slot and also a micro slot in a distal end of the blade that connects with the irrigation slot.

  • Publication number: 20170325878
    Abstract: Aspects of the present disclosure are presented for a single surgical instrument configured for performing sealing procedures on tissues using electrosurgical or ultrasonic energy, irrigating tissue at the sealing site, and evacuating material from the sealing site. An end effector of the surgical instrument may include multiple members arranged in various configurations to collectively perform the aforementioned functions. The evacuation and irrigation elements may comprise one or more fluid paths configured to remove material from or deliver fluid to a surgical field. The instrument may include electrical and mechanical aspects that may be used to control the evacuation and irrigation functions. In this way, a user may use a single surgical instrument to perform these tasks during a tissue sealing procedure.

  • Patent number: 9788888
    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.

  • Publication number: 20170119465
    Abstract: A variety of electrical ablation apparatuses and methods are disclosed. In one embodiment, an ablation apparatus includes an injector catheter electrode having a proximal end configured to couple to an energy source and a fluid source. A distal end of the injector catheter defines an injection needle and defines an electrically conductive hollow channel for communicating a fluid from the fluid source to a treatment site. A balloon electrode is in fluid communication with a balloon catheter. The balloon catheter has a proximal end configured to couple to the energy source and the fluid source and a distal end configured to inflate the balloon electrode.

  • Publication number: 20170105789
    Abstract: Aspects of the present disclosure are presented for a single surgical instrument configured for grasping tissue, performing sealing procedures using electrosurgical or ultrasonic energy, suctioning fluid, and providing irrigation. An end effector of the surgical instrument may include multiple members arranged in various configurations to collectively perform the aforementioned functions. The suction and irrigation elements may comprise one or more fluid paths configured to deliver fluid to or evacuate fluid from a surgical field. In this way, a user, such as a clinician or surgeon, may rely on a single surgical instrument to perform these tasks typical in surgery while having an extra hand available and so as to not need to divert his or her concentration away from the surgical site in order to access multiple devices. Further, the timing for performing each of the functions may be made quicker, due to not needing to switch using multiple devices.

  • Patent number: 9277957
    Abstract: An electrosurgical system may generally first and second electrodes coupled to an energy source operative to generate and deliver pulses of a biphasic radio frequency (RF) waveform to treat undesirable tissue in a patient. The pulses may induce non-thermal cell death in the patient's tissue while causing no or minimal muscle contractions in the treated patient. The pulses may be grouped in bursts wherein the pulses within a burst repeat at a particular pulse frequency.
