Abstract
A surgical instrument for implanting electrodes within the muscular tissue of the diaphragm of a mammal through the abdomen. The instrument has an elongate frame with a first handle at one end. A needle for carrying the electrode is rotatably mounted on the other end of the instrument. The needle is located within a channel below the outer surface of the frame when the instrument is not in use. A second handle is connected to the needle by an actuating mechanism such that when the instrument is operated by moving the second handle toward the first handle, the needle rotates out from the frame to enable the instrument to accurately implant the electrode.
