An electrical stimulation lead for a target nerve includes a sleeve having an inner surface and an outer surface, the inner surface defines a nerve channel. A longitudinal slit extends from the outer surface to the nerve channel and along an entire length of the sleeve. A width of the slit retains the target nerve within the nerve channel when the sleeve is closed and releases the target nerve when open. A plurality of electrodes are disposed on the inner surface of the sleeve. A flexible transition element electrically couples a lead body to the plurality of electrodes. Upper and lower sections of the sleeve rotates about a common hinge line (e.g., like a clam shell) located directly opposite the longitudinal slit. The material along the common hinge line remains “elastic” when the sleeve is moved from closed to open, and vice-versa.
