An electrode assembly comprising: an elongate cuff body including: a base member including a top wall, a bottom wall, a first side wall, and a second side wall; a first flange member including a first end and a second end; and a pair of resilient arcuate-shaped flange members including a second flange member and a third flange member, the respective flange members (134, 150) each including a proximal portion configured to extend away from the other respective proximal portion, and a distal portion configured to extend toward the other respective distal portion, wherein the second flange member is configured to extend outwardly away from the second side wall of the base member at an angle thereto and the third flange member is configured to extend outwardly away from the first side wall of the base member at an angle thereto, and wherein the base member and the two flange members (134, 150) define a lumen and wherein the distal portions define an opening configured to provide access to the lumen, and wherein both the flange members (134, 150) are configured to extend a length of the cuff body, wherein the first end of the first flange member is secured to an outer surface of the third flange member and is configured to extend from the secured first end to be in releasable contact with both a portion of the third flange member and the second flange member and to overlap the portion of the third flange member, the opening, and the second flange member, and wherein the second end of the first flange member is configured to terminate at a location over the second flange member; and a row of generally rigid electrode elements embedded within the cuff body and spaced apart from each other along the length of the cuff body. an elongate cuff body including: a base member including a top wall, a bottom wall, a first side wall, and a second side wall;
