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.

Abstract: A medical electrical lead and a method of its use. The lead has an elongated lead body having an outer circumference and provided with an electrode. A push tube is mounted circumferentially around the lead body and the lead body is longitudinally movable with respect thereto. A fixation helix is mounted to the push tube, extending along a generally helical axis around the outer circumference of the lead body. The lead may be employed by advancing the lead to a desired location for the fixation helix and then rotating the push tube to secure the helix to tissue. The lead body may then be moved longitudinally with respect to the push tube to place the electrode in a desirable location.

Abstract: The present disclosure may comprise an improvement to the prior art leads as disclosed above. One embodiment is directed to an intravenous medical electrical lead that includes an elongated lead body. The elongated lead body comprises a length between proximal and distal ends with a longitudinal axis extending therebetween. The distal end of the lead body includes a plurality of electrodes forming first and second pairs of electrodes. The first pair of electrodes comprises one electrode electrically connected to another electrode circumferentially and diagonally spaced apart along the longitudinal axis. The second pair of electrodes comprising one electrode electrically connected to another electrode circumferentially and diagonally spaced apart along the longitudinal axis.
