发明名称 Electrosurgical method and apparatus for removing tissue within a bone body
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.
