Abstract

An implantable medical device (IMD) comprises a plurality of deep tines configured to be advanced into a septum of a heart of a patient in different directions that are not parallel to a longitudinal axis of the implantable medical device, wherein each deep tine of the plurality of deep tines is configured to deliver cardiac pacing to cardiac tissue distal to a chamber of the heart in which the IMD is implanted, and one or more shallow electrodes engageable with the septum, wherein the one or more shallow electrodes are configured to deliver cardiac pacing to the chamber of the heart in which the IMD is implanted.

Claims (9)

1 . An implantable medical device (IMD) comprising:

a deep electrode that is configured to be advanced into a septum of a heart of a patient; and

a plurality of shallow tines configured to transition from a deformed state to a less deformed state to engage with the septum, the plurality of shallow tines being selectable to form one or more return electrodes configured to deliver, in tandem with the deep electrode, pacing therapy to a target site within the septum.

2 . The IMD of claim 1 , wherein the deep electrode comprises a helical electrode.

3 . The IMD of claim 1 , wherein the deep electrode is configured to be advanced into the septum to a ventricular myocardium of the heart of the patient.

4 . The IMD of claim 1 , wherein the target site comprises at least one of a left bundle branch (LBB), a right bundle branch (RBB), or a bundle of His (Hb) of the heart.

5 . The IMD of claim 1 , wherein the plurality of shallow tines are engageable with the septum via piercing of the septum.

6 . The IMD of claim 1 , wherein the plurality of shallow tines comprises a plurality of electrically common pairs of shallow tines.

7 . The IMD of claim 1 , wherein the plurality of shallow tines are configured to, during the transition from the deformed state to the undeformed state, pierce tissue of the septum and pull the IMD towards an outer surface of the septum.
