A technology is described for determining an intended movement from neuromuscular signals. An example method () includes receiving electromyography (EMG) data corresponding to single-ended channels of an electrode array (), where EMG signals are detected by electrodes comprising the single-ended channels of the electrode array and the EMG signals are converted to the EMG data. Determining differential channel pairs for the single-ended channels of the electrode array () and extracting feature data from the EMG data of the differential channel pairs (). Thereafter a feature data set is selected from the feature data of the differential channel pairs () and the feature data set is input to a decode model configured to correlate the feature data set to an intended movement (). Decode output is received from the decode model indicating the intended movement () and the decode output is provided to a device ().

A medical implant device () is disclosed that can protect and shield an implant () as the implant () moves through body tissue. The medical implant device () can comprise a main body portion () having a payload opening () to receive a payload (i.e., an implant). The medical implant device () can also comprise a tapered nose portion () at a front end () of the medical implant device () extending from the main body portion () and configured to penetrate body tissue. In addition, the medical implant device () can comprise a payload coupling interface () configured to couple the implant () to the main body portion ().

A technology is described for an electronic peripheral nerve stimulation system. The electronic nerve stimulation system can include a stimulation device and an electrode array. The stimulation device can be operable to generate a high-frequency alternating current. The electrode array can be operable to apply the high-frequency alternating current received from the stimulation device to selected subpopulations of peripheral nerve fibers within a peripheral nerve to block transmission of neural signals along the selected subpopulations of peripheral nerve fibers within the peripheral nerve.

A technology is described for an electronic nerve stimulation system. The electronic nerve stimulation system can include a stimulation device operable to generate a high-frequency alternating current. The electronic nerve stimulation system can include one or more wearable electrodes operable to apply the high-frequency alternating current from the stimulation device to peripheral nerves to provide an electrical stimulation of neuronal tissue to treat pain. The one or more wearable electrodes can interface with the stimulation device via a connection system.

The invention includes an osseointegrated mount and electrical connector, suitable for providing neural control and sensory feedback for an advanced prosthetic limb. The device provides a channel in which a lead wire from the peripheral nerve interface can travel from the electrical connector down the side of the device or within the device to limit potential sites of infection to a single transcutaneous breach. The channel allows for a silicone barrier to be installed between the internal and external components.

A system and method for electrically shielding a physiological pathway from electrical noise is disclosed. The method includes the operation of implanting at least one signal microelectrode into a patient such that the signal microelectrode is proximate to the physiological pathway. An additional operation includes substantially enclosing the microelectrode and a section of the physiological pathway with an electrical shielding wrap. The electrical shielding wrap includes a plurality of holes that enable fluid communication of physiological fluids between an inside and outside of the wrap.

A microelectrode array system used to sense physiological signals and stimulate physiological tissue to form signals is disclosed. The array includes a dielectric substrate and a two dimensional array of signal microelectrodes substantially perpendicular to and integrated on the dielectric substrate. At least one reference microelectrode is located adjacent to and integrated with the signal microelectrodes on the dielectric substrate. The reference microelectrodes are positioned on the dielectric substrate relative to the signal microelectrodes to enable a reduced level of electrical noise to be detected between the reference microelectrodes and the recording microelectrodes.
