    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 device may generally comprise first and second electrodes coupled to an energy source operative to generate and deliver a first sequence of electrical pulses and a second sequence of electrical pulses to tissue having a necrotic threshold, wherein the first sequence of electrical pulses delivers a first energy dose that is less than the necrotic threshold to induce thermal heating in the tissue and the second sequence of electrical pulses delivers a second energy dose equal to or greater than the necrotic threshold to induce cell necrosis in the tissue by irreversible electroporation. The first sequence of electrical pulses may each be independently characterized by a first amplitude, a first pulse width, and a first frequency. The second sequence of electrical pulses may be characterized by a second amplitude, a second pulse width, and a second frequency.

    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.

    摘要: Ablation probes for ablating cardiac tissue through a patient's natural orifice and methods for ablating cardiac tissue through a patient's natural orifice. In some embodiments, an ablation probe, which may include electrodes, a radio frequency probe or a cryoprobe, is inserted through an incision made through the patient's esophagus. A balloon catheter may be inserted through the incision after it has been made to expand the area between the heart and the esophagus. The ablation probe is then brought into contact with the cardiac tissue and activated to irreversibly damage the tissue. The ablation probes may employ vacuum to retain the tissue in contact with the probe during ablation.
