    摘要: A surgical instrument can comprise two positive electrodes positioned along a first line, and two negative electrodes positioned along a second line, wherein the first line can be perpendicular to the second line. The positive electrodes can be positioned further away from a central axis than the negative electrodes in order to expand the voltage field created by the electrodes. In various embodiments, a surgical instrument can comprise a first array of electrodes positioned along a first line and a second array of electrodes positioned along a second line. In at least one embodiment, the first array of electrodes can comprise both positive and negative electrodes, and, in addition, the second array of electrodes can comprise both positive and negative electrodes.

    摘要: An electrical ablation apparatus comprises first and second electrodes. Each electrode comprises a first end configured to couple an energy source and a second end configured to couple to a tissue treatment region. An energy source is coupled to the first and second electrodes. The energy source is configured to deliver a first series of electrical pulses sufficient to induce cell necrosis by irreversible electroporation and a second series of electrical pulses sufficient to induce cell necrosis by thermal heating, through at least one of the first and second electrodes. The first series of electrical pulses is characterized by a first amplitude, a first pulse length, and a first frequency. The second series of electrical pulses is characterized by a second amplitude, a second pulse length, and a second frequency.
