摘要：
This invention provides a device for implantation directly into the spinal cord for the purpose of treating back pain. Electrodes on a backing that conforms directly to the spinal cord are installed as a source of electrical stimulation and pain relief. The electrode array is maintained on the spinal cord by way of a spring or support structure that is anchored to an anatomical structure outside the spinal cord but near the site of implantation. Suitable anchoring structures include the vertebrae and the dura. Secured in this fashion, the support structure maintains a gentle pressure of the electrode array against the spinal cord so as to stay in electrical contact but minimize injury or inflammation. The device may accommodate and buffer movement of the spinal cord both laterally and in a caudal-rostral fashion so that the electrode array remains in place.
