A method of determining and treating disordered tissue in a patient incites energy signal generation from disordered tissue. An energy sensor structure obtains an energy signal from tissue of a patient. The obtained energy signal is compared in a processor circuit to a known energy signal of the same tissue under normal functioning of the tissue. The tissue is identified as disordered tissue when the comparing step determines that the obtained energy signal is different from the known energy signal. The disordered tissue is localized within the patient via the energy signal. A bodily disorder caused by the localized disordered tissue is diagnosed by an AI module. The bodily disorder is then treated.

The present invention describes a system that uses ultrasonic waves to transfer energy and data, enabling for the control and recharging of a cardiac assist device. Data and energy transfer are accomplished using pulsed ultrasonic waves. The use of ultrasonic waves allows for wireless transcutaneous energy transfer to power the cardiac assist device pump in absence of a driveline, reducing complications associated with driveline infections and improving patient quality of life.

The following relates generally to measuring a patients O.sub.2 level with a mote implanted in the patient's tissue. For example, a mote implanted in a patients tissue may be powered by ultrasound (US) signals generated by an ultrasound interrogator that is external to the patient. Components on the mote may be duty cycled off to advantageously decrease power consumption. A luminescence sensor on the mote may be used to measure the O.sub.2 level, and the luminescence sensor may be optically isolated from the patients tissue by an opaque material such as black silicon.

Systems and methods for managing communication strategies between implanted medical devices. Methods include temporal optimization relative to one or more identified conditions in the body. A selected characteristic, such as a signal representative or linked to a biological function, is assessed to determine its likely impact on communication capabilities, and one or more communication strategies may be developed to optimize intra-body communication.

A biometric sensor includes a body surface sensor and an e-field signal transmitter. The body surface sensor create a drive-sense signal at a first frequency based on one or more sensing parameters. When operably coupled to a body via one or more electrodes, the body surface sensor provides the drive-sense signal to the body and detects an effect on the drive-sense signal based on electrical characteristics of the body. The body surface sensor generate a data signal based on the detected effect, wherein the data signal represents the body’s electrical characteristics. The e-field signal transmitter generates an outbound signal reference at a second frequency based on the data signal and one or more transmit parameters. The e-field transmitter drives the outbound reference signal to the body, wherein the outbound reference signal is transmitted within at least a portion of the body as an outbound e-field signal at the second frequency.
