摘要： A catheter assembly comprising a elongated, flexible support structure having an axis. The assembly also includes an elongated porous electrode assembly carried by the support structure along the axis for contact with tissue. The elongated porous electrode assembly comprises a wall having an exterior peripherally surrounding an interior area, a lumen to convey a medium containing ions into the interior area, and an element coupling the medium within the interior area to a source of electrical energy. At least a portion of the wall comprising a porous material is sized to allow passage of ions contained in the medium to thereby enable ionic transport of electrical energy through the porous material to the exterior of the wall to form a continuous elongated lesion pattern in tissue contacted by the wall. The support structure can have a curvilinear geometry, e.g., a loop shape, and the elongated porous electrode assembly conforms to the curvilinear geometry.

摘要： Systems and methods for controlling the power supplied to an electrosurgical probe. The systems and methods may be used to monitor electrode-tissue contact, adjust power in response to a loss of contact, and apply power in such a manner that charring, coagulum formation and tissue popping are less likely to occur.

摘要： Systems and methods for locating an operative element within an interior body space use a locating probe, which includes at least one transmitting element to transmit an electric waveform output within at least a portion of the space. The systems and methods also use a sensing element, which is adapted to be carried by the operative element to sense a local electric waveform within the space. A processing element coupled to the sensing element generates a processed output that locates the sensing element relative to the locating probe based, at least in part, upon a differential comparison of the waveform output and the sensed local waveform.
