Patent ID: 7925343

Claim:
An implantable system, comprising: a defibrillator device subcutaneously implantable superficial to a left atrium of a heart wherein the defibrillator device comprises control logic configured to detect for ventricular fibrillation based on sensed cardiac activity; a patch device subcutaneously implantable superficial to an apex of the heart, wherein the patch device comprises control logic, wherein the patch device is communicatively coupled with the defibrillator device via a wireless communication link a subcutaneously implantable wire electrically coupling the defibrillation device with the patch device; and a sensor configured to sense cardiac activity, the sensor communicatively coupled with the defibrillator device through the wire such that sensed cardiac activity is received by the defibrillator device; wherein in response to the defibrillator device detecting ventricular fibrillation in the heart, the defibrillator device administers a defibrillation shock via the patch device.
