METHOD AND INSTRUMENT FOR TREATING INTERVERTEBRAL DISC, AND METHOD FOR INCREASING CONDUCTIVITY OF FISSURE IN FIBROUS RING OF INTERVERTEBRAL DISC

摘要

PROBLEM TO BE SOLVED: To provide a method for treating an intervertebral disc enabling a clinician to heat only the target tissue up to the end point of desired coagulation or denervation to substantially prevent damage inflicted on adjacent healthy tissue.;SOLUTION: This method for treating the intervertebral disc comprises a process for applying a solution 79 of high conductivity to a fissure 77; a process for disposing a first electrode 73 adjacently to the solution of high conductivity; and a process for applying voltage difference of sufficiently high frequency between the first electrode 73 and a second electrode 75 so that an electric current enough to treat at least a part of adjacent first and second collagen tissue regions flows through the solution of high conductivity.;COPYRIGHT: (C)2004,JPO
