摘要: The present invention provides systems and methods for selectively applying electrical energy to a target location within a patient's body, particularly including tissue in the spine. The present invention applies high frequency (RF) electrical energy to one or more electrode terminals in the presence of electrically conductive fluid or saline-rich tissue to contract collagen fibers within the tissue structures. In one aspect of the invention, a system and method is provided for contracting a portion of the nucleus pulposus of a vertebral disc by applying a high frequency voltage between an active electrode and a return electrode within the portion of the nucleus pulposus, where contraction of the portion of nucleus pulposus inhibits migration of the portion nucleus pulposus through the fissure.

摘要: Apparatus and methods for treating an inter-vertebral disc by ablation, coagulation, shrinking, stiffening, or other treatment of disc tissue. A method of the invention includes positioning at least one active electrode within the inter-vertebral disc, and applying at least a first high frequency voltage between the active electrode(s) and one or more return electrode(s), wherein the volume of the nucleus pulposus is decreased, pressure exerted by the nucleus pulposus on the annulus fibrosus is reduced, and discogenic pain of a patient is alleviated. An apparatus of the invention includes an electrosurgical probe, an introducer needle adapted for passing the distal end of the probe therethrough, and a positioning unit for monitoring a position of the probe in relation to the introducer needle.

摘要: The present invention provides systems and methods for selectively applying electrical energy to a target location within the head and neck of a patient's body, particularly including tissue in the ear, nose and throat. The present invention applies high frequency (RF) electrical energy to one or more electrode terminals in the presence of electrically conductive fluid to remove and/or modify the structure of tissue structures. The present invention is particularly useful for treating sleep obstructive disorders, such as sleep apnea and snoring.
