1. A system comprising:
- a first implantable medical device coupled to a first plurality of electrodes, wherein the first implantable medical device is configured to deliver therapeutic electrical stimulation to a patient via the first plurality of electrodes; and
a second medical device coupled to a second plurality of electrodes, wherein the second medical device is configured to;
deliver therapeutic electrical stimulation to the patient via the second plurality of electrodes to inhibit the delivery of therapeutic electrical stimulation by the first implantable medical device; and
modulate the therapeutic electrical stimulation delivered by the second implantable medical device according to a predetermined pattern to provide a disable command to the first implantable medical device,wherein the first implantable medical device is disabled in response to receipt of the disable command.

Abstract
Various techniques for disabling a first implantable medical device (IMD) by modulation of therapeutic electrical stimulation delivered by a second medical device are described. One example method includes delivering therapeutic electrical stimulation from a more recently implanted second IMD at a higher average rate than the previously implanted first IMD so that only the more recently implanted IMD will administer therapy, and modulating stimulation by the more recently implanted IMD in order to send a disable command to the previously implanted IMD.

8. An implantable medical device comprising:
-
a housing; a therapy delivery module within the housing, wherein the therapy delivery module is coupled to a plurality of electrodes and configured to deliver therapeutic electrical stimulation to a patient via the electrodes; and a processor within the housing, the processor configured to; control the therapy delivery module to deliver the therapeutic electrical stimulation to inhibit delivery of therapeutic electrical stimulation by another implantable medical device; and modulate the therapeutic electrical stimulation according to a predetermined pattern to provide a disable command to the other implantable medical device, wherein the other implantable medical device is disabled in response to receipt of the disable command. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16)

23. A method for disabling a first medical device previously implanted within a patient with a second implanted medical device more recently implanted in the patient, the method comprising:
-
controlling a therapy delivery module of the more recently implanted medical device to deliver a signal to the patient via at least one electrode that is coupled to the more recently implanted medical device and implanted within the patient; modulating the signal by the more recently implanted medical device to provide a disable command to the previously implanted medical device; detecting the signal by the previously implanted medical device via at least one electrode that is coupled to the previously implanted medical device and implanted within the patient and a sensing module of the previously implanted medical device that is configured to detect intrinsic electrical activity of the patient via the electrode; and identifying, by the previously implanted medical device, the disable command within the detected signal, wherein the previously implanted medical device is disabled in response to receipt of the disable command. - View Dependent Claims (24, 25, 26)
