Abstract: This invention provides an device for electrical stimulation of the spinal cord. The device has an electrode assembly with a sufficiently thin profile to be implanted between the pial surface of the spinal cord and the dura mater, and secured to the dura. Electrodes on the electrode assembly are directed towards the surface of the spinal cord, and connected through the dura to a signal generator located outside the dura. Following implantation, the subject is treated by transmitting electrical signals from the signal generator through the leads to the electrodes, stimulating the subject's spinal cord.

Abstract: A method for treating intractable pain via electrical stimulation of the spinal cord. Remote, non-contact stimulation of a selected region of spinal cord is achieved by placement of a transceiver patch directly on the surface of that region of spinal cord, with said patch optionally being inductively coupled to a transmitter patch of similar size on either the outer or inner wall of the dura surrounding that region of the spinal cord. By inductively exchanging electrical power and signals between said transmitter and transceiver patches, and by carrying out the necessary electronic and stimulus signal distribution functions on the transceiver patch, the targeted dorsal column axons can be stimulated without the unintended stray stimulation of nearby dorsal rootlets. Novel configurations of a pliable surface-sheath and clamp or dentate ligament attachment features which realize undamaging attachment of the patch to the spinal cord are described.

Abstract: Described in this disclosure is a support structure for an electrode array configured for implanting against the spinal cord for treatment of pain. The restoring force of the support structure works in concert with frictional coupling between the array and the spinal cord to overcome the inertial force associated with ateral motion of the array. The electrode array is supported with struts that run longitudinally across or near the array backing. For example, two struts can be affixed on either out-board longitudinal edge of the array. The electrode array can be further stabilized by securing to a vertebra in the patient using a strap equipped with a collar that encircles the bundle of electrical leads emerging from the array through the dura. Positional stability of the array is better than 0.5 nm per movement cycle, thereby inhibiting the array from lifting off of the spinal cord during movement of the spinal cord within the dura.
