Adjustable nerve electrode
First Claim
1. A method comprising:
- adjusting a geometric configuration of an adjustable electrode to arrange two or more contacts around a nerve in an onset response mitigating configuration;
applying an electrical waveform to the nerve;
blocking an onset response of the electrical waveform due to the onset response mitigating configuration;
after a period of time, adjusting the geometric configuration of the adjustable electrode to arrange the two or more contacts around the nerve in a block maintenance configuration andmaintaining a nerve conduction block to the nerve.

Abstract
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 may also include 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.
