Catheters, Spinal, Intervertebral Disc, Radiofrequency Ablation
Definition : Spinal catheters designed for introduction into an intervertebral disk to perform ablation by delivering radiofrequency (RF) current through the tissues. These catheters include a needle electrode at the distal tip to deliver the RF current to a neutral electrode located externally on the patient's skin (i.e., monopolar systems). The catheter is usually introduced through a hollow needle previously inserted percutaneously in the disc and is then maneuvered around the outer edge of the central nucleus of the disc. Power is supplied to the catheter from an RF generator that includes connectors and/or adapters specially designed for use with the catheter. RF ablation intervertebral disc catheters are used in outpatient procedures to treat chronic, long-term discogenic pain.
