Apparatus and system to stimulate a nerve
First Claim
Patent Images
1. An electrode apparatus comprising:
- an electrode body of a substantially flexible and non-conductive material, the electrode body having a generally cylindrical configuration with a diameter; and
at least a pair of electrodes along an inner surface of the electrode body, the pair of electrodes being spaced axially apart from each other by a repeat distance that is functionally related to the diameter and that approximates a distance at which a given fascicle of a nerve, having the substantially the same diameter, periodically reconstitutes along an axial length of the nerve.

Abstract
An electrode apparatus can includes an electrode body of a substantially flexible and non-conductive material, the electrode body having a generally cylindrical configuration with a diameter. At least a pair of electrodes along an inner surface of the electrode body are spaced axially apart from each other by a repeat distance that is functionally related to the diameter and that approximates a distance at which a given fascicle of a nerve, having the substantially the same diameter, periodically reconstitutes along an axial length of the nerve.

13. A stimulation system comprising:
-
an electrode body of a substantially flexible and non-conductive material, the electrode body having a generally cylindrical configuration with a diameter; and
a plurality of electrodes along an inner surface of the electrode body, at least one pair of the electrodes being spaced axially apart from each other by a repeat distance that is functionally related to the diameter of the electrode body and that approximates a distance at which a given fascicle of a nerve, having the substantially the same diameter, periodically reconstitutes along an axial length of the nerve;
a substantially resilient lead assembly extending outwardly from a substantially central location of the electrode body at an angle that is transverse relative to the exterior sidewall of the electrode body; and
a signal generator that is electrically coupled to provide an electrical signal to the electrodes through lead wires that are attached to the electrode body by the lead assembly. - View Dependent Claims (14, 15, 16, 17)

18. An electrode apparatus comprising:
-
an electrode body of a substantially non-conductive material, the electrode body having a longitudinal sidewall that extends axially between spaced apart ends of the electrode body, the sidewall having an exterior sidewall portion and having an interior sidewall portion that defines a lumen dimensioned and configured for engaging a nerve; and
a plurality of electrodes along the interior sidewall; and
a lead assembly that extends longitudinally from a central portion of the exterior sidewall axially toward one of the ends of the electrode body to resiliently maintain a set of at least one lead wire substantially at a predetermined angle relative to the exterior sidewall portion of the electrode body. - View Dependent Claims (19, 20, 21, 22, 23, 24)
