A first of the planetary gearsets has members selectively connectible with a ground or stationary member through a synchronizer clutch. During implantation the open sides of the cuff are closed so as to capture the nerve in the cuff in a single motion. The first elastic member is fastened between the fixing member and the second end, the rotating member is rotated relative to the fixing member to drive the second end to slide on the fixing member to compress or release the first elastic member. The conductive paths include paths for dedicated bidirectional tester channels and shared bidirectional tester channels.
