Abstract: A system and method for anchoring an electrode that stimulates a dorsal root ganglion. The anchoring device includes a screw, collet, and locking cap. The screw is inserted into bone of the pars interarticularis and the electrode is inserted through the screw and positioned next to the dorsal root ganglion for stimulation. The screw includes a recess that is shaped to fit the collet. The collet has flexible arms. When assembled, the locking cap forces the collet into the recess thereby moving the flexible arms inward radially, impinging on the electrode and holding the electrode in place adjacent the dorsal root ganglion.

Abstract: A surgical lead is provided which includes a generally flexible polymeric panel incorporating a set of electrode arrays embedded in one side. The electrode arrays are connected to integrally formed leads which house conductors that connect the electrodes to a set of contacts. The contacts engage an IPG header. The leads incorporate an optical fiber which extends from the IPG header to a set of window portals in the flexible panel. Each of the fibers includes a side firing section adjacent the optical windows for transmission or reception of light. Optimally placed reflectors and heat shields are also provided.

Abstract: A percutaneous lead is provided which includes a generally tubular, multi-duct, flexible lead body. The lead body supports a distal set of electrodes and a proximal set of contacts which are connected by conductors in the ducts. The lead body further houses an optical fiber with a side firing section. The side firing section is held adjacent an optical transmission window, integrally formed with the flexible lead body. A cylindrical ferrule is provided to position the fiber in the header of an IPG.

Abstract: An implantable pulse generator is provided comprising a non-metallic shell adjacent a header. The header abuts an optical window in the shell. The header aligns a series of surgical or percutaneous leads with the optical window. The leads incorporate optical fibers, electrodes and contacts which distribute stimulation signals. Behind the optical window, a set of optical devices is provided which transmit or receive light from the fibers. Signal processors are provided to interpret the signals from the optical fibers, and to mitigate a continuous inductive charging function.

Abstract: The invention relates to a system and method for improving spinal cord stimulation (SCS) by simultaneously modulating ascending and descending pain pathways. The invention utilizes a Randomized Intermittent Dichotomous Stimulation (RIDS) paradigm, introducing a randomly timed target stimulation signal interspersed with a background stimulation signal. This novel method enhances the cognitive processing of pain signals by utilizing event-related potentials, such as the P300 brain potential, to activate both inhibitory pathways and minimize pain habituation. The target stimulus, distinct from the background SCS signal, elicits a cognitive response by prompting the patient to recognize the target and perform a physical or mental task. This simultaneous modulation of pain pathways increases treatment efficacy, extends the longevity of SCS therapy, and reduces habituation effects, offering an optimized therapeutic solution for chronic pain management.

Abstract: The Randomized Intermittent Dichotomous Stimulation (RIDS) paradigm disclosed provides an alternate stimulus for the patient to attend to, besides the typical SCS signal, thus providing a somatotopically-matched non-noxious stimulus to replace the cognitive attention to the nociceptive stimulus. The randomly intermittent stimulus is paired with an implicit virtual task to reinforce selective attention to the non-noxious stimulus.

Abstract: This disclosure provides an SCS system comprised of an adaptive IPG. The IPG selectively chooses certain burst pulse parameters according to a pattern of frequencies and amplitudes that are determined by a low power hardware circuit. Alternatively, the patterns of frequencies and amplitudes are dictated by a predetermined list of parameters from a table of limited length. The IPG also is capable of receiving and storing vital sign telemetry, and spinal cord position to train an adaptive neural network to produce paresthesia pulses. Training of the IPG takes place after closing. Retraining the neural network allows the system to adapt to habituation, lead migration, and physiological changes in the patient's condition to maintain efficacy of the system over time. Training the neural network is also accomplished outside the IPG by a separate processor, which serves to conserve battery power and facilitate frequent retraining.

Abstract: The system incorporates a feed forward control system which automatically adjusts mean stimulation current to maintain consistent dosing of electrical current applied to the spinal cord despite motion of the spinal cord relative to the epidural electrode array. Optical boundary conditions are captured using a sample and hold circuit when the spinal cord is in its most dorsal position (supine patient position) and most ventral position (prone or sitting positions). Optimal mean stimulation current is manually set for these two ordinal positions during setup. During operation, the mean current is actively modulated by interpolating the mean current between the two current boundary conditions using a nominally inverse linear relation to the instantaneous optical reflectance which is bounded by the optical boundary conditions.
