    摘要: The invention provides an electrosurgical unit comprising a radio-frequency power source and a pump, with the throughput of fluid expelled by the pump controlled by the RF power level setting and fluid flow rate setting. The invention also provides various electrosurgical devices which may be used with the electrosurgical unit. In one embodiment, the electrosurgical device comprises a first electrode tip spaced next to a second electrode tip with a portion of the first electrode tip facing the second electrode tip and a portion of the second electrode tip facing the first electrode tip, the first electrode tip and the second electrode tip both having a spherical distal end, and a fluid outlet arrangement to expel fluid onto the electrode tips solely at locations remote from the electrode tip portions facing each other.

    摘要: An electrosurgical balloon includes an inflatable balloon body formed of a non-conductive substrate material. One or more electrodes are disposed on an exterior surface of the balloon body. The electrodes can include a pair of bipolar electrodes, and the balloon body can have at least one fluid outlet hole configured to provide fluid to the pair of bipolar electrodes. A second inflatable balloon body can be disposed inside the first inflatable balloon body. The electrosurgical balloon can be incorporated into a catheter assembly, in which the electrosurgical balloon is a balloon electrode tip at a distal end of a catheter.

    摘要: A bipolar electrosurgical device includes a shaft and an electrode tip coupled to a distal end of the shaft. At least a portion of the electrode tip extends distally beyond the distal end of the shaft and includes an insulator extending between a first electrode and a second electrode. The first electrode is configured to he an active electrode and the second electrode is configured to be a return electrode. The electrode tip can include a substantially conically-shaped portion, or can include a spherical portion and a cylindrical portion protruding from the spherical portion at a non-zero angle with respect to a longitudinal axis of the shaft. The substantially conically-shaped portion can include at least a portion of one of the first electrode and the second electrode. The distal end of the shaft can include a fluid outlet opening to provide fluid from a fluid source onto the first electrode and the second electrode.

    摘要: Surgical devices for treating tissue are provided. Also provided are systems for treating tissue and methods of treating tissue. An exemplary surgical device has a handle, a fluid passage connectable to a fluid source, a tip portion and a distal end. The tip portion can simultaneously provide RF power and conductive fluid to tissue. The tip portion includes an electrode having a domed portion having a domed surface and a cylindrical portion having a cylindrical surface. The domed portion is located distal to the cylindrical portion and occupies at least a portion of the distal end of the surgical device. The device includes a fluid outlet opening in fluid communication with the fluid passage, the fluid outlet opening configured to provide the conductive fluid to a surface of the electrode proximal to the distal end surface of the surgical device.
