SpineCATH IDET therapy is usually performed on an outpatient basis. Local anesthesia and mild sedation may be used to reduce discomfort during the procedure. You will be awake and alert so that you can provide important feedback to the physician. With the guidance of x-ray images, your physician will advance a needle into the disc. The SpineCATH catheter will be passed through the needle and into the disc. Once it is in the appropriate position, the temperature of the heating section of the catheter will be gradually increased, raising the disc wall temperature. During the heating protocol, your physician will monitor your condition and comfort level closely. You will most probably feel a reproduction of your usual lower back pain. This is a indication that the heat is being applied to the appropriate areas. Once the therapy is completed, the catheter and needle are removed, and you will likely be sent home with a Band-Aid over the needle insertion site.
