Abstract: Devices, and methods of use thereof, are disclosed for preventing tumor seeding when withdrawing the device along an entry-exit path. Some embodiments of the present invention comprise a method of withdrawing a probe through a tissue via a path that traverses at least some bone tissue, the method including withdrawing the probe through the path, and at least partially concurrently delivering energy in a bipolar manner from the probe to heat a layer of tissue surrounding the probe to a temperature sufficient for thermal coagulation necrosis of cells. The device may be withdrawn incrementally.

Abstract: An electrosurgical probe with internal cooling for use in systems and methods for lesioning in bone and other tissue is disclosed. The probe includes a distal electrical insulator, a proximal electrical insulator, a distal electrical conductor defining a distal electrode with a closed distal end and a proximal electrical conductor defining a proximal electrode, the distal electrode longitudinally spaced apart and electrically isolated from the proximal electrode by the distal electrical insulator. The distal electrode has a closed proximal end formed by a distal face of the distal electrical insulator to thereby define a closed distal inner lumen for circulating the cooling fluid. The proximal electrode has a closed distal end formed by a proximal face of the distal electrical insulator and a closed proximal end formed by a distal face of the proximal electrical insulator to thereby define a closed proximal inner lumen for circulating the cooling fluid.

Abstract: An electrosurgical bipolar probe with internal cooling for use in systems and methods for lesioning in bone and other tissue is disclosed. The bipolar probe includes tubular electrodes configured such that the inner surface of the electrodes are cooled, directly or indirectly, while keeping the electrodes electrically isolated. An exemplary disclosed method of using a bipolar probe having an active tip having at least two electrodes for delivering energy includes the steps of: advancing the active tip into a bone tissue; delivering energy substantially between the electrodes in a bipolar manner; and supplying cooling fluid to the active tip for internal cooling of the electrodes. Some versions of the method further include the steps of monitoring the temperature of tissue to which the energy is being delivered; and controlling the delivery of energy in suspense to the temperature of the tissue.
