    摘要： A method of treating spinal tissue of a patient's body is disclosed, the method using a system comprising an energy source and first and second internally-cooled probe assemblies, wherein each of the probe assemblies comprises an electrically conductive energy delivery device electrically coupled to the energy source. The method comprises: inserting the energy delivery devices of the first and second internally-cooled probe assemblies into spaced-apart treatment sites for the spinal tissue; delivering energy from the energy source to the spinal tissue through the energy delivery devices to create a lesion within the spinal tissue; delivering a cooling fluid to the energy delivery devices; and controlling the delivery of energy and the delivery of the cooling fluid to the energy delivery devices such that the lesion extends between the energy delivery devices.

    摘要： A medical probe assembly, system, and methods for the use thereof to treat tissue are described. The system optionally comprises an energy source, two internally-cooled probe assemblies, and one or more cooling devices to provide cooling to at least one of the probe assemblies. The probe assemblies may be configured in a bipolar mode, whereby current flows preferentially between the probe assemblies. The probe assemblies and system described herein are particularly useful to deliver radio frequency energy to a patient's body. RF energy delivery may be used for various applications, including the treatment of pain, tumor ablation and cardiac ablation.

    摘要： A method and apparatus are disclosed for improving accuracy of placement of a cannula during delivery of electrical energy proximate to bodily tissue, e.g. neural structures. The apparatus optionally includes a cannula operable to deliver electrical current where a portion of the cannula is electrically insulated and a portion of the cannula is exposed and electrically conductive. The cannula further includes a radiopaque marker to identify a specific portion of the cannula, for example to differentiate the electrically insulated region from the electrically exposed region, by allowing it to be more clearly delineated using fluoroscopy or other radiographic imaging techniques. The radiopaque marker is optionally tapered in order to reduce the force required to insert a cannula comprising a radiopaque marker into the patient's body.
