An illustrative system is configured to perform a process comprising: directing stimulation to be applied to a recipient of a bilateral hearing system that includes a first cochlear implant associated with a first ear of the recipient and a second cochlear implant associated with a second ear of the recipient; and causing the first cochlear implant and the second cochlear implant to simultaneously record, during an acquisition time window, one or more evoked responses within the recipient that are elicited by the stimulation.

The present disclosure relates to a tinnitus suppression device, method, system and computer program. In some aspects, a tinnitus suppression device comprises a receiver module configured to receive sound signals, a processing module operably connected to a memory and to the receiver module, and a neurostimulation module operably connected to the processing module. In some aspects, the processing module and the neurostimulation module may be configured to determine a received sound signal that corresponds to a template stored in the memory, that is above a preconfigured threshold, preferably above a preconfigured threshold which is specific for the individual, or both. A multi-channel neurostimulation signal encoding the determined sound signal may be generated and applied to a neurostimulation device of the individual that may be configured to directly stimulate afferent sensory neurons of the central nervous system of the individual and thereby to elicit, for each channel of the neurostimulation signal, one or more non-auditory, preferably somatosensory, perceptions in a cortex area of the individual.

A balance prosthesis device for an individual including a sensor module configured to obtain a sensor signal indicative of a balance or equilibrium state of the individual, a processing module configured to determine at least one neurostimulation signal based at least in part on the obtained sensor signal, and a transmitter module configured to transmit the determined neurostimulation signal to a neurostimulation device of the individual. The neurostimulation signal is configured to elicit an artificial sensation in a specific sensory cortex area of the individual via directly stimulating afferent sensory axons of the central or peripheral nervous system of the individual targeting sensory neurons of the sensory cortex area not directly associated with vestibulocortical pathways of the individual. The elicited artificial sensation provides a balance indication to the individual in order to support, mimic, substitute or enhance the natural sense of balance of the individual.

A leadless pacing device for implanting into an atrium of a heart. The leadless device comprises an implant anchor for connecting the device to an inner wall of the atrium; a stimulator for a direct stimulation of the atrium; a sensor for sensing a ventricular activity of the heart corresponding to the direct stimulation of the atrium. Further aspects relate to a system comprising such leadless pacing device, a method and a computer program that may be executed by such leadless pacing device.

A biphasic implant stimulator includes a direct stimulation supply generator that receives an RF AC input and converts it into a DC voltage ramp for fully-adiabatic stimulation of tissue though electrodes. Current control feedback is used instead of current-sources which reduces energy loss. The current control feedback senses the current in the electrode-tissue load and keeps it constant for the duration of the stimulation. Energy stored in the electrode capacitance is replenished. No bulky inductor is required for operation.

Systems and methods directed to controlling a magnetic spinal cord stimulation system and model-based stimulation plan are provided. A magnetic spinal cord stimulation system includes at least one magnetic coil and a power source. The power source is operatively connected to the at least one magnetic coil to deliver an electric current to the at least one magnetic coil. A controller receives a plurality of input parameters. The controller utilizes an electromagnetic and neurophysiological prediction model to create a stimulation plan based on the plurality of input parameters. The control controls the power source and the model-based stimulation plan to deliver the electrical current through the at least one magnetic coil. Time-varying magnetic fields are created that induce stimulating electric fields within spinal cord tissue at a depth to directly stimulate motor pathways in the spinal cord.

The invention belongs to the technical field of nerve regulation and control, and particularly relates to a percutaneous electrical nerve regulation and control system and method for pudendum nerve regulation and pelvic symptom treatment, and the system comprises a flexible skin patch module and a stimulation host; the stimulation host generates biphase symmetric pulse waves and transmits the biphase symmetric pulse waves to the flexible skin patch module, and the output current intensity is in a range higher than an individual sensory threshold value of a user but lower than an individual motion threshold value of the user, so that A beta sensory nerve fibers of perineum subcutaneous tissues are activated. Through the design of each module of the system, non-invasive electrical stimulation with specific parameters is realized, A beta sensory nerve fibers in a perineum region are selectively activated, different from muscle contraction caused by direct stimulation of motor nerves in the prior art, functional remodeling of a central nervous system can be initiated, and the perineum can be effectively stimulated. Therefore, long-acting and physiologic regulation of pelvic organ functions is realized.
