Cuff electrode

A method of fabricating a cuff electrode comprising:

• forming a cuff body to define a base, a first arm, and a second arm,
• wherein:
• the first arm defines at least one increased thickness portion and extends from the base in a first circumferential direction to a distal end,
• the at least one increased thickness portion is circumferentially spaced from the base and from the distal end,
• a thickness of the at least one increased thickness portion at an apex thereof is greater than a thickness of at least a portion of the first arm circumferentially between the at least one increased thickness portion and the base,
• and further wherein the second arm extends from the base in a second circumferential direction opposite the first circumferential direction to exteriorly overlap a portion of the first arm including the at least one increased thickness portion;
• and further wherein the first and second arms are biased to self-assume a closed configuration of the cuff body in which the second arm exteriorly overlaps the first arm;
• arranging at least one array of first electrodes to extend axially on the cuff body in a first orientation;
• and
• arranging a second array of second electrodes to extend circumferentially on the cuff body in a second orientation, including at least one electrode of the second array of second electrodes being housed by the first arm at a location radially aligned with the at least one increased thickness portion.
