ABSTRACT:
Myocardial sutureless unipolar lead including an insulated conductor coil adjacent to a base pad, and a barbed electrode spaced adjacent to the base pad and connected to the conductor coil. The sutureless myocardial unipolar lead requires no stab wound or sutures for electrode placement and support. The barbed electrode is secured to the heart by gently pushing the tip into the myocardial tissue and the electrode is thereby secured to the myocardial tissue. The lead accepts a stiffening stylet for controlling the stiffness to aid in placement of the electrode within the myocardial tissue, and without the need for further insertion tool. The angle of the barbed electrode determines the specific application of the lead for ventricular or atrial pacing applications.
