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: In some examples, a system includes an implantable medical device configured for implantation in a chamber of the heart, an extension attached to the implantable medical device, the extension comprising a housing comprising at least one electrode, the housing defining a hole, and a tether comprising a first tether portion and a second tether portion and configured to be threaded through the hole. When the tether is threaded through the hole, the first tether portion and the second tether portion are on opposite sides of the hole. The tether may be used to implant the extension in a different chamber of the heart of the patient than the implantable medical device.
