<p>A transvenous lead (1) specifically designed for coronary sinus implantation. The lead features a fixation ring (2) positioned adjacent to the electrode. The ring is constructed so as to be readily pliable and bent. The ring (5) functions to wedge or fix the lead (1) within the coronary sinus in such a manner that the electrode (10) is pushed against the vessel wall while the flow of blood through the vessel is not impeded. In alternative embodiments the electrode is positioned on the ring itself. In further alternative embodiments the distal portion of the lead features a prebent nose to assist in the positioning of the lead into the coronary sinus. The nose may be oriented relative to the ring in any acceptable manner to permit the ring and the electrode to be properly positioned relative to anywhere along the coronary sinus wall.</p> |
