Abstract
Systems and methods provide intrabody communication using acoustic telemetry. The system includes a first or control implant including a first acoustic transducer, and a second implant including a switch and a second acoustic transducer coupled to the switch. The second acoustic transducer receives acoustic signals from the first acoustic transducer for closing the switch to activate the second implant. The second implant may include a sensor for measuring a physiological parameter that is transmitted using acoustic signals including the physiological data to the first implant. For example, the second implant may measure pressure in the patient's heart that may be used by the first implant to control a pacemaker. Alternatively, the second implant may blood sugar concentration that may be used by the first implant to control an insulin pump. Alternatively, the first implant may store and transfer the data to an external device for monitoring the patient.
