摘要： Example adjustable electrodes are described. One example adjustable electrode includes two or more contacts configured to selectively deliver high frequency alternating current (HFAC) to a nerve in an amount sufficient to produce an HFAC nerve conduction block in the nerve. The example adjustable electrode also includes a logic configured to selectively control which of the two or more contacts deliver HFAC to the nerve to control whether the nerve electrode is in a first (e.g., onset response mitigating) configuration or in a second (e.g., HFAC nerve conduction block maintenance) configuration. The electrode may be used in applications including, but not limited to, nerve block applications, and nerve stimulation applications. The electrode may be adjusted by changing attributes including, but not limited to, the number, length, orientation, distance between, surface area, and distance from a nerve of contacts to be used to deliver the HFAC.

摘要： Example ionic coupling electrodes are described. One example ionic conducting electrode includes a first portion that can be coupled to a single phase current source. The first portion carries current flow via electrons. The electrode includes a second portion to apply a current to a nerve tissue. The second portion carries current flow via ions. The second portion is positioned between the nerve tissue and the first portion to prevent the first portion from touching the nerve tissue. The current applied to the nerve tissue is produced in the second portion in response to a current that is present in the first portion. The current present in the first portion is provided from a single phase current source. The electrode may be used in applications including, but not limited to, nerve block applications and nerve stimulation applications.

摘要： An example method for selectively and reversibly preventing the conduction of action potentials in a targeted nerve region is presented. The method includes generating an electrical waveform having two phases and selectively depolarizing a nerve membrane using the electrical waveform. The nerve membrane is depolarized to a state where the nerve membrane cannot conduct an action potential. The depolarization is achieved by selectively repetitively providing the electrical waveform to a targeted nerve region associated with the nerve region to control m gates and h gates in the region and thus to control the availability of ions.

摘要： A method of blocking signal transmission through a nerve with reduced onset activity includes applying an HFAC to an axon of a nerve to block the transmission of signals through the axon. The method may also include applying a direct current (DC) to the axon, increasing the amplitude of the DC over time to a predetermined amplitude, applying the HFAC, and then decreasing the DC. The method may also include temporarily reducing the amplitude of the HFAC to permit the transmission of signals through the axon and subsequently increasing the amplitude to block transmission without triggering an onset response. The method may also include temporarily applying an unbalanced charge to the nerve and then balancing the charge over time.
