Abstract: Systems and methods for positioning implanted devices in a patient are disclosed. A method in accordance with a particular embodiment includes, for each of a plurality of patients, receiving a target location from which to deliver a modulation signal to the patient's spinal cord. The method further includes implanting a signal delivery device within a vertebral foramen of each patient, and positioning an electrical contact carried by the signal delivery device to be within ±5 mm. of the target location, without the use of fluoroscopy. The method can still further include, for each of the plurality of patients, activating the electrical contact to modulate neural activity at the spinal cord. In further particular embodiments, RF signals, ultrasound, magnetic fields, and/or other techniques are used to locate the signal delivery device.

Abstract: The present technology is directed generally to a lead anchor for positioning and securing spinal cord modulation leads and associated systems and methods. In at least some contexts, the lead anchor includes a central lumen surrounded by a restriction feature. The restriction feature can interface with a tightening screw or other actuator and can be configured to provide a radial compressive fit around the lead body. In some embodiments, the clamp can be disengaged upon twisting or other unlocking motion to release the lead.

Abstract: Various embodiments concern assessing a degenerative cognitive disorder of a patient based on a plurality of episodes of non-motor epileptiform bioelectrical activity. The non-motor epileptiform bioelectrical activity can be detected from one or more bioelectrical brain signals. A worsening cognitive disorder may be indicated by an increase in one or more of intensity, duration, and frequency of occurrence of the episodes of non-motor epileptiform bioelectrical activity. A therapy can be delivered to reduce one or more of intensity, duration, and frequency of occurrence of the episodes of non-motor epileptiform bioelectrical activity. The delivery of the therapy can be controlled based on the plurality of episodes of non-motor epileptiform bioelectrical activity.
Abstract: The present invention provides an electrode array for a medical implant device, comprising a substrate supporting a plurality of electrodes, the substrate comprising at least two layers of material including a first layer and a second layer, wherein the first layer of material and the second layer of material have different coefficients of thermal expansion. The plurality of electrodes may be supported on the first layer of material, and are preferably incorporated in and/or project from the second layer of material. The second layer of material may itself have a layered structure comprising multiple material layers, with the plurality of electrodes incorporated within the said multiple material layers. The first layer of material preferably has a higher coefficient of thermal expansion than the second layer of material. The invention furthermore provides a medical implant device including an electrode array according to the invention, and a method of manufacturing such an electrode array.
Abstract: An implantable stimulator includes a device for delivering a stimulus and a casing having a first, metal portion and a second, portion which is formed from a plastic or polymer. A method of forming an implantable stimulator includes preparing a coil on a ferrite tube and molding a casing body on the coil, such that the coil is embedded in a wall of the casing which is formed of a plastic or polymer. Another method of forming an implantable stimulator includes forming an annular metal connector and molding a plastic or polymer casing body on the metal connector.

Abstract: An electrode for continuously stimulating a facial nerve root capable of a stable holding required for an electrode that continuously stimulates a facial nerve root, and an apparatus for monitoring electromyograms of facial muscles using the electrode for continuously stimulating the facial nerve root, are provided. The electrode for continuously stimulating the facial nerve root comprises an electrode unit, a contact unit, a guard unit, an extension unit, and a wire unit. The electrode for continuously stimulating the facial nerve root is held by clamping the extension unit between the facial nerve root and the anterior inferior cerebellar artery or the small artery so that the contact unit closely contacts to the facial nerve root and is fixed.
Abstract: Selective high-frequency spinal cord modulation for inhibiting pain with reduced side effects and associated systems and methods are disclosed. In particular embodiments, high-frequency modulation in the range of from about 1.5 KHz to about 50 KHz may be applied to the patient's spinal cord region to address low back pain without creating unwanted sensory and/or motor side effects. In other embodiments, modulation in accordance with similar parameters can be applied to other spinal or peripheral locations to address other indications.

Abstract: An apparatus comprises a medical device configured for implantation into a living organism. The medical device comprises processing circuitry, a memory and interface circuitry configured for communication with a monitoring device. The medical device is configured to receive a request for access from the monitoring device, to measure a physiological value of the living organism, to perform a pairing protocol with the monitoring device, the pairing protocol comprising a secure channel set-up phase followed by an authentication phase, and to permit access by the monitoring device responsive to a successful pairing in accordance with the pairing protocol, the successful pairing being based at least in part on a determination that a physiological value supplied by the monitoring device substantially matches the measured physiological value. The medical device performs the secure channel set-up phase before sending the measured physiological value to the monitoring device.
