Variable Multi-contact Circumferential Cuff Micro-construction; (a) Attachment of silk strands 90° to the left and right of the 6mm polyurethane tube. Knots are located at a 5 mm (top knots) and 1 mm (bottom knots) length. (b) Insertion of the 270° gold pin wire for the longitudinal cuff at the upper 270° lead marks using a needle. (c) 5 µL pipette tip pressing the top and bottom 270°, 120°, and 60° uninsulated gold pin wire portions against the inside wall of the 6mm polyurethane tube. (d) Frontal upside-down view of the Variable Multi-contact Circumferential Cuff. Image location of the 60° electrodes (first and fourth in a top-down order), 120° electrodes (second and fifth in a top-down order), and 270° electrodes (third and sixth in a top-down order).
