Abstract
A stylet and introducer tool is used with a screw-in electrode which is adapted to attach living tissue to a pulse generator, such as a pacemaker or the like. The stylet has a knob at its proximal end and extends through the introducer tool and coiled conductor of the lead to engage a helix assembly positioned within the hollow electrode of the lead. The stylet is adapted to urge the helix of the helix assembly into contact with the living tissue. The knob of the stylet engages in a slot in the introducer tool to lock the stylet to the introducer tool and permit the screw-in lead to be rotated around the stylet so that the helix will penetrate the living tissue.
