1. An electrode cuff comprising:
- a first elongate portion configured with a length to removably contact, and be aligned generally parallel to, length of a nerve, the first elongate portion having a first side edge and a second opposite side edge, both of which extend generally parallel to the length of the first elongate portion;
a second elongate portion to extend outwardly from, and perpendicular relative to, the first edge of the first elongate portion, wherein the second elongate portion is biased to, and has a length sufficient to, releasably encircle the nerve and at least partially overlap the second opposite side edge of the first elongate portion; and
a first single series of at least three electrodes disposed on and spaced apart longitudinally along the length of the first elongate portion,wherein the at least partially overlapping portion of the second elongate portion has a width less than the length of the first elongate portion, with the width being less than a distance of separation between two outer electrodes of the at least three electrodes extending along the length of the first elongate portion.

Abstract
An electrode cuff includes a first elongate portion and a second elongate portion. The first elongate portion is configured to removably contact a length of a nerve while the second elongate portion extends outwardly at an angle relative to a first side edge of the first elongate portion to at least partially wrap about the nerve. The electrode cuff includes a first series of electrodes that is spaced apart longitudinally along the first elongate portion. A width of the second elongate portion is sized to fit between adjacent branches extending from a nerve.

9. An electrode cuff comprising:
-
a first elongate portion configured with a length to removably contact, and be aligned generally parallel to, a length of a nerve, the first elongate portion having a first side edge and a second opposite side edge, both of which extend generally parallel to the length of the first elongate portion; a second elongate portion to extend outwardly at an angle between 40 to 50 degrees relative to the first side edge of the first elongate portion, wherein the second elongate portion is biased to, and has a length sufficient to, releasably encircle the nerve and at least partially overlap the second opposite side edge of the first elongate portion; and a first single series of at least three electrodes disposed on and spaced apart longitudinally along the length of the first elongate portion, wherein the at least partially overlapping portion of the second elongate portion has a width less than the length of the first elongate portion, with the width being less than a distance of separation between two outer electrodes of the at least three electrodes that extend along the length the first elongate portion. - View Dependent Claims (10, 11, 12)

13. A method of implanting a nerve electrode cuff, comprising:
-
maneuvering an electrode cuff within a body to position a length of a first elongate portion of the electrode cuff to be aligned generally parallel to, and removably contact, a length of a first nerve, wherein the first elongate portion includes a first side edge and a second opposite side edge, both of which extend generally parallel to the length of the first elongate portion; providing the electrode cuff to include a first single series of at least three electrodes disposed on and spaced apart longitudinally along the first elongate portion; providing the electrode cuff to include a second elongate portion to extend outwardly at an angle relative to a first side edge of the first elongate portion; maneuvering the second elongate portion to extend between adjacent nerve branches extending outward from the first nerve, wherein the second elongate portion is biased to, and has a length sufficient to, encircle the first nerve with a distal end of the second elongate portion at least partially overlapping with a second opposite side edge of the first elongate portion, wherein a width of the at least partially overlapping portion of the second elongate portion is less than the length of the first elongate portion and less than a distance of separation between two outer electrodes of the at least three electrodes extending along the length of the first elongate portion, and wherein the width of the second elongate portion is less than a gap between the two adjacent nerve branches. - View Dependent Claims (14, 15, 16)
