Abstract
A lead implanted in a body to apply electrical stimulation to body organs includes an electrode wire having one end provided as an insertion portion to be inserted into a body and another end provided as an interface portion for connection with an external device; a first electrode in the insertion portion to transmit electrical stimulation to body organs; a second electrode on the interface portion to receive electrical stimulation applied from outside; a signal line that interconnects the first electrode and second electrode to transmit electrical stimulation received by the second electrode to the first electrode; and a ring member that covers the first electrode and has an opening for exposing the first electrode in a portion of a circumferential direction, and is mounted to be movable in a longitudinal or circumferential direction with respect to the electrode wire by an external force to adjust an exposure position of the first electrode.
