Abstract
Disclosed herein are systems and methods for nerve conduction block. The systems and methods can utilize at least one rechargeable electrode. The methods can include delivering a first direct current with a first polarity to an electrode proximate nervous tissue sufficient to at least partially block conduction in the nervous tissue.
Claims27
A method for nerve block of a patient utilizing a rechargeable implanted electrode, comprising:
- generating a first current of a first polarity through the rechargeable implanted electrode proximate a nerve sufficient to at least partially block conduction in the nerve;
- wherein the first current comprises a first waveform, wherein a slope of a leading ramp of the first waveform is less steep than a trailing ramp of the first waveform;
- and
- generating a second current of a second polarity opposite the first polarity through the rechargeable implanted electrode proximate the nerve sufficient to at least partially block conduction in the nerve,
- wherein the second current comprises a second waveform, wherein a slope of a leading ramp of the second waveform is less steep than a trailing ramp of the second waveform, and
- wherein the first waveform and the second waveform each form a trapezoidal shape when viewed on a time axis.

A method for nerve block of a patient utilizing an implanted electrode, comprising:
- generating a first current of a first polarity proximal to the implanted electrode comprising a high charge density material proximate a nerve sufficient to at least partially block conduction in the nerve, wherein the first current decreases an amount of stored charge in the implanted electrode;
- dynamically sensing the amount of the stored charge in the implanted electrode while delivering the first current;
- ceasing delivery of the first current when the amount of the stored charge is sensed to reach a pre-determined threshold value;
- and
- generating a second current of a second polarity opposite the first polarity through the implanted electrode, wherein the second current increases the amount of the stored charge of the implanted electrode to recharge the implanted electrode,
- wherein the first current comprises a first waveform, wherein a slope of a leading ramp of the first waveform is less steep than a trailing ramp of the first waveform,
- wherein the second current comprises a second waveform, wherein a slope of a leading ramp of the second waveform is less steep than a trailing ramp of the second waveform, and
- wherein the first waveform and the second waveform each form a trapezoidal shape when viewed on a time axis.
