摘要： Systems and associated methods for sensing and indicating when a wide range of tissue is adequately cauterized and/or sealed by an electrosurgical instrument. The system indirectly monitors the current flowing through the tissue and determines the adequacy of tissue cauterization or sealing of vessel(s) by monitoring when the current is stable or nearly stable (i.e. when the current is constant). The system may also indicate a predetermined time that current is applied through the tissue and control the flow of energy through the tissue.

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： 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.

摘要： A surgical instrument, such as an endoscopic or laparoscopic instrument, includes an ablation device. The ablation device includes an elongate relatively flexible member having a proximal end and a distal end, the flexible member includes at least a first working channel. A first and second electrode extends from a working channel at the distal end of the flexible member. The first and second electrodes are adapted to be endoscopically located in a tissue treatment region. The first and second electrodes are adapted to couple to an electrical waveform generator to receive an irreversible electroporation electrical waveform sufficient to ablate tissue located between the first and second electrodes. The waveform parameters of the irreversible electroporation electrical waveform are determined based on image information received from the tissue treatment region.

摘要： A surgical instrument, such as an endoscopic or laparoscopic instrument, includes an ablation device. The ablation device includes an elongate member having first and second channels. First and second probes are disposed within the respective first and second channels. The first and second probes each define a central axis. The first and second probes each have substantially straight distal ends protruding from the distal ends of the respective first and second channels. The substantially straight distal ends define an outer surface. First and second electrodes are attached to a portion of the outer surface of the substantially straight distal ends of the respective first and second probes. The first and second electrodes are positioned in juxtaposed relationship with the central axis of the first and second probes. A distance between the first and second electrodes is adjustable by rotating at least one of the first and second probes about the respective central axis of the at least one of the first and second probes.
