Abstract: A medical electrical lead having an elongated lead body and a fixation helix extending along a generally helical axis, mounted around the outer circumference of the lead body. The fixation helix has a free end spaced from and extending from the lead body for less than the circumference of the lead body. The lead body includes an additional component which provides a rotation stop extending from the outer circumference of the lead body and provides stop surface generally perpendicular to the axis of the helix.

Abstract: A single-pass pacing lead capable of sensing and pacing both the atria and the ventricles is described. In some examples, the single-pass pacing lead is connected to a DDD pacemaker. In some examples, the single-pass pacing lead comprises four electrodes. In some examples, the lead includes three electrodes configured to be positioned in or near an atrium, e.g., the right atrium, and one electrode configured to be positioned in or near a ventricle, e.g., the left ventricle, when the lead is implanted. In other examples, the lead includes two electrodes configured to be positioned in each of the atrium and ventricle when the lead is implanted. In some examples, one of the electrodes, which is configured to be positioned proximate the coronary sinus ostium when the lead is implanted, comprises a helical element for fixation of the lead to tissue.

Abstract: This disclosure describes implantable medical leads that include a lead body and an electrode. A width of the electrode as measured along a longitudinal direction of the lead varies about the perimeter of the lead. The uneven width of the electrode may bias a stimulation field in a particular direction, e.g., a radial or transverse direction relative to the longitudinal axis of the lead. Electrodes with an uneven width may be useful for controlling the direction of propagation of the stimulation field in order to, for example, avoid phrenic nerve stimulation during LV pacing or neck muscle stimulation during vagal neurostimulation.

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 relatively compact implantable medical device includes a fixation member formed by a plurality of fingers mounted around a perimeter of a distal end of a housing of the device; each finger is elastically deformable from a relaxed condition to an extended condition, to accommodate delivery of the device to a target implant site, and from the relaxed condition to a compressed condition, to accommodate wedging of the fingers between opposing tissue surfaces at the target implant site, wherein the compressed fingers hold a cardiac pacing electrode of the device in intimate tissue contact for the delivery of pacing stimulation to the site. Each fixation finger is preferably configured to prevent penetration thereof within the tissue when the fingers are compressed and wedged between the opposing tissue surfaces. The pacing electrode may be mounted on a pacing extension, which extends distally from the distal end of the device housing.

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.
