Abstract
The present invention may comprise an improvement to the prior art leads as disclosed above. In a preferred embodiment, the invention comprises an intravenous medical electrical lead that includes an elongated lead body. The elongated lead body comprises a length between a proximal end and a curved distal end, the lead body defining a longitudinal axis extending between the proximal end and the curved distal end. The lead body having an outer circumference and provided with a set of electrodes circumferentially spaced apart. Each electrode includes an electrically active portion and an insulated portion at an outer circumference of the electrode. The lead body is further configured to move through a coronary vein while substantially retaining its curved distal end. The lead body may freely move longitudinally within a delivery catheter that guides the lead to myocardial tissue. If the lead body rotates within the delivery catheter, the lead body is configured to rotate back into a position such that the electrically active portion of a set of electrodes faces myocardial tissue when exiting the guide catheter while the insulated portion of electrode are diametrically opposed to neural tissue such as the phrenic nerve.
