Abstract

A transvenous lead specifically designed for coronary sinus implantation. In the preferred embodiment the lead features an electrode which is eccentricity placed along the lead body. Disposed on the opposite side of the lead body is a tine-like member to push or maintain the electrode into contact with the vessel wall. Because the electrode and tine-like member do not entirely block the cross sectional area of the vessel, blood flow through the vessel is not impeded. Through such a configuration electrical stimulation with the tissue comprising the left side of the heart may be accomplished. In alternative embodiments other mechanisms besides tine-like member are used to maintain the contact of the electrode with the vessel wall. In a still further alternative embodiment the eccentricity disposed electrode is positioned instead upon the tip of the tine.
