A cuff electrode assembly for implantation on a target nerve, the cuff electrode assembly comprising: a resilient cuff body configured to be disposed about the target nerve, the cuff body including a first end portion having a first free end, a second end portion having a second free end, and a pinch hinge portion that connects the first end portion to the second end portion, wherein the cuff body is pre-formed to define a closed configuration having a generally helical shape in which the cuff body is wound about a longitudinal axis, the longitudinal axis extending through a center of the helical shape in a proximal-distal orientation, wherein in the closed configuration the cuff body extends helically with the first and second end portions overlapping one another in different planes such that the first free end is proximal of the pinch hinge portion with respect to the longitudinal axis while the second free end is distal of the pinch hinge portion with respect to the longitudinal axis; a first arm member and a second arm member each projecting radially outward from the cuff body and spaced from one another along the cuff body, wherein the cuff body is configured such that a force applied to urge the first and second arm members toward one another causes relative deflection of the second free end and the first free end so as to define an open configuration of the cuff body configured to allow the cuff body to be positioned around the target nerve; an electrode disposed at least partially within or on the cuff body oriented to provide an electrical stimuli to the target nerve when the cuff body is disposed about the target nerve; and a stiffening member configured to urge the cuff body to return to the pre-formed closed configuration upon release of a force causing the cuff body to assume the open configuration, wherein the stiffening member is a metallic, electrically conductive element configured to operate as the electrode of the cuff electrode assembly. a resilient cuff body configured to be disposed about the target nerve, the cuff body including a first end portion having a first free end, a second end portion having a second free end, and a pinch hinge portion that connects the first end portion to the second end portion, wherein the cuff body is pre-formed to define a closed configuration having a generally helical shape in which the cuff body is wound about a longitudinal axis, the longitudinal axis extending through a center of the helical shape in a proximal-distal orientation, wherein in the closed configuration the cuff body extends helically with the first and second end portions overlapping one another in different planes such that the first free end is proximal of the pinch hinge portion with respect to the longitudinal axis while the second free end is distal of the pinch hinge portion with respect to the longitudinal axis; a first arm member and a second arm member each projecting radially outward from the cuff body and spaced from one another along the cuff body, wherein the cuff body is configured such that a force applied to urge the first and second arm members toward one another causes relative deflection of the second free end and the first free end so as to define an open configuration of the cuff body configured to allow the cuff body to be positioned around the target nerve; an electrode disposed at least partially within or on the cuff body oriented to provide an electrical stimuli to the target nerve when the cuff body is disposed about the target nerve; and a stiffening member configured to urge the cuff body to return to the pre-formed closed configuration upon release of a force causing the cuff body to assume the open configuration, wherein the stiffening member is a metallic, electrically conductive element configured to operate as the electrode of the cuff electrode assembly.
