An electrode assembly to be installed on a patient's nerve has a thin, flexible, electrically insulating circumneural carrier with a split circumferential configuration longitudinally attached to a lead at the distal end thereof. The carrier possesses circumferential resiliency and has at least one flexible, elastic electrode secured to the underside thereof and electrically connected to an electrical conductor in said lead. A fastener serves to close the split configuration of the carrier to prevent separation from the nerve after installation of the electrode assembly onto the nerve. Tear away webbing secured to adjacent serpentine segments of the lead near the carrier enables the lead to lengthen with patient movements.

The method according to claim 10, wherein each of said electrode devices is a tripolar electrode which includes a central cathode for producing said electrode-generated action potentials by cathodic stimulation, a first anode on one side of the cathode for making said electrode-generated action potentials unidirectional, and a second anode on the opposite side of said cathode for producing a selective anodal blocking of said electrode-generated action potentials. 17. Apparatus for blocking pain sensations resulting from the propagation of body-generated action potentials towards the central nervous system through a nerve bundle having small-diameter sensory fibers and large-diameter sensory fibers, comprising: an electrical device adapted to be applied to said nerve bundle and having at least one electrode device capable, upon actuation, of generating unidirectional action potentials to be propagated through both the small-diameter and large-diameter sensory fibers in said nerve bundle away from said central nervous system; a
