ABSTRACT:
A spinal electrode for use in spinal cord stimulation included in a laminar hook so that displacement of the electrode cannot easily occur by normal bodily motion as is a failure mechanism of prior electrode designs. The electrical contacts of the electrode are disposed on the underside of the blade portion of the hook. The head of the hook, which seats above the lamina, is coupled either to the spinous process, or to the head of a hook which is positioned in an opposing orientation. The head of the hook in one embodiment includes a hole through which a wire may be passed to tie the hook to the spinous process, or to the other hook. In a second embodiment, the head of the hook has a notch formed in it so that it may receive an elastomeric band which is used to couple the head of the hook to the spinous process, or to another hook.
