Patent Images
1. A method for communicating information between first and second implantable medical devices implanted within a patient, the method comprising:
- generating a therapeutic electrical stimulation pulse using the first device, the stimulation pulse encoded with information to be communicated to the second device;
delivering the encoded therapeutic stimulation pulse to patient tissue in a first heart chamber;
detecting a far-field version of the therapeutic stimulation pulse within tissues of a second chamber of the patient'"'"'s heart using the second device; and
decoding the detected pulse using the second device to extract the encoded information.

10. An implantable cardiac stimulation system for delivering cardiac stimulation therapy to the heart of a patient, the system having first and second separately implanted devices, comprising:
-
an encodable pulse generator provided within the first device and operative to generate an encoded therapeutic electrical stimulation pulse for delivery to patient tissues in a first heart chamber, the pulse encoded with information to be communicated to the second device; and an encodable pulse detector provided within the second device and operative to detect a far-field version of the encoded therapeutic stimulation pulse within patient tissues in a second chamber of the patient'"'"'s heart and to decode the pulse to extract the encoded information.
