1. A system comprising:
- an implantable medical device having a proximal end and a distal end and configured to be implanted in a chamber of a heart of a patient, the implantable medical device comprising;
a first housing;
a pacing circuit enclosed by the first housing;
a battery enclosed by the first housing; and
at least one fixation element at the distal end of the implantable medical device, wherein the at least one fixation element is configured to engage with tissue of the patient; and
an extension attached to the proximal end of the implantable medical device, the extension comprising;
a distal end attached to the proximal end of the implantable medical device;
a proximal end; and
a second housing located at the proximal end of the extension and comprising at least one electrode positioned greater than 3 centimeters from the proximal end of the implantable medical device, the second housing defining a hole for attachment to a tether.

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.
