Patent ID: 7912537

Claim:
A system of autonomous implantable medical devices, the system comprising: a first implantable medical device for interacting with a first region of a body of a patient, the first implantable medical device comprising an ECG monitor; a second implantable medical device for interacting with a second region of the body of the patient, the second implantable medical device comprising an EEG monitor; an inter-device telemetry link for wirelessly linking the first and second implantable medical devices; and a trigger circuit in the first implantable medical device which, when triggered in response to a detected event based on a first physiologic parameter, transmits a trigger signal via the inter-device telemetry link to the second implantable medical device; wherein the second implantable medical device initiates storage of data of a second physiological parameter in response to its receipt of the trigger signal, such that the trigger signal causes the second implantable medical device to store data of the second physiological parameter substantially simultaneously with storage of data of the first physiological parameter.
