ABSTRACT:
An implantable cardiac lead system suitable for placement in the coronary sinus region of the heart. The lead system comprises a lead having two or more non-helical bends in its distal portion. The two or more non-helical bends cooperate to prevent the lead from dislodgment or displacement inside the coronary sinus. The lead system may further comprise a stylet suitable for steering the lead into at least one of the coronary sinus vein, great cardiac vein, left marginal vein, left posterior ventricular vein, and small cardiac vein. The stylet is tapered in its distal portion to provide enhanced maneuverability and steerability inside the coronary sinus region. The lead system may also comprise an introducer which aids in introducing the lead into the heart.
