Abstract

A system for alerting a patient includes a ventricular assist device (VAD), a battery, and an alarm system. All of these components of the system are configured to be implanted within the patient. The implanted alarm system is configured to provide an alert to and from within the patient based on a condition. The alert can be a vibration or an electrical shock, and the condition can be the implanted battery being below a threshold, a failure of the implanted battery, an error of the implanted battery, or an error of the implanted VAD.

Claims

1. A system for alerting a patient, the system comprising:

a ventricular assist device (VAD) configured to be implanted within the patient;

a battery configured to be implanted within the patient and for providing power to at least the implanted VAD; and

an alarm system configured to be implanted within the patient and to provide an alert to and from within the patient based on a condition.

2. The system of claim 1 wherein the alarm system is configured to provide a vibration to and from within the patient.

3. The system of claim 1 wherein the alarm system is configured to provide an electrical shock to and from within the patient.

4. The system of claim 1 wherein the alarm system is configured to provide the alert based on the implanted battery being below a threshold.

5. The system of claim 1 wherein the alarm system is configured to provide the alert based on a failure of the implanted battery.

6. The system of claim 1 wherein the alarm system is configured to provide the alert based on an error of the implanted VAD.

7. The system of claim 1 wherein the alarm system is configured to provide the alert based on an error of the implanted battery.
