Abstract

A spinal electrode for use in spinal cord stimulation having portions which are specifically provided for coupling the electrode to the adjacent spinal tissue so that displacement of the electrode cannot easily occur by normal bodily motion as is a failure mechanism of prior electrode designs. The distal end of the electrode which includes the electrical contacts also includes at least one laterally extending non-electrical portion. The extending portions are provided for receiving a suture or wire therethrough. The laterally extending portions may include a readily identifiable distinguishing feature, such as a color dye or a textural difference, so that it can be readily seen as a safe region through which a suture may be passed. Alternatively (or in addition), the laterally extending portions may include a through hole so that the tip of the electrode may be tied to the spinous process (or other spinal bone) by a wire.
