The sutureless myocardial lead introducer herein disclosed includes a handle having at the distal end thereof means for releasably holding a body tissue electrode for screwing into body tissue and is provided with a longitudinal slot extending toward the center of the handle and extending from adjacent the distal end thereof to the proximal end thereof to receive an insulated electric lead from the electrode. A hollow tube slides over the handle and holds the electric lead in place in the groove. A tunneling rod is slidably mounted within the handle and is provided with a fin which engages a locking slot at the proximal end of the handle. The fin may be disposed from a first position, wherein the fin is disposed in the locking slot, to a second position, wherein the tunneling rod engages the electrode to push the electrode clear of the handle, when the electrode has been screwed into the body tissue and when the tube has been removed from the handle releasing the electric lead from the slot in the handle.
