    摘要： A method for treating a bone body comprises inserting a probe having at least one active electrode into the target tissue and applying a voltage difference between an active electrode and return electrode to ablate the tissue. The method is particularly directed to removing tumors in a bone body and or removing cancellous bone in a bone body. The bone body may be a vertebral body. An apparatus includes a plurality of active electrodes and a distal section including two bends. The bends serve to prevent the active electrodes from impinging upon the shaft of an introducer needle. Also, a kit includes an electrosurgical probe, an electrosurgical generator, an introducer needle, and a fluid connector to connect the introducer needle to a fluid source such that liquid may be supplied to the target site during an application.

    摘要： Apparatus and methods for treating a target tissue by delivering a fluid at a defined temperature to a patient's body. An apparatus of the invention includes a fluid delivery unit for delivering fluid in at least close proximity to the target tissue, an aspiration unit for withdrawing the fluid, and a fluid source unit for providing the fluid at the defined temperature. A method of the invention includes forming a void in at least close proximity to the target tissue, and circulating a preheated fluid through the void, wherein the target tissue undergoes adjustment from body temperature to a treatment temperature due to heat exchange between the fluid and the target tissue.
