Abstract

A control system for use with a medical device implanted within a patient. The system is included within a control circuit connected to a medical device and when said control circuit detects at least one error with the medical device or patient, the controller activates at least one audible alarm and wherein the audible alarm plays a voice message to the patient through an audio transducer, and the speaker of the audio transducer is disposed externally relative to the body of the patient.

Claims

1. A control system for use with a medical device implanted within a patient, wherein said system is included within a control circuit connected to said medical device and when said control circuit detects at least one error with said medical device or patient, said controller activates at least one audible alarm and wherein the audible alarm plays a voice message to said patient through an audio transducer and characterised in that the speaker of said audio transducer is disposed externally relative to the body of the patient.

2. The control system of claim 1, wherein each error corresponds to a different voice message.

3. The control system of claim 2, wherein at least one voice message may be changed after the control system has been manufactured.

4. The control system of claim 3, wherein at least one voice message may be recorded and stored by the control system, when a user speaks in the audio transducer.

5. The control system of claim 3, wherein at least one voice message may be stored by the control system, after being recorded and transmitted by a personal computer connected to said control system.

6. The control system of claim 5, wherein the medical device is a left ventricular assist device.

7. A portable external controller adapted to be operably connected to a blood pump implanted within a patient said controller comprising a control circuit for monitoring and controlling the operation of said pump, an audible alarm device operably connected to said control circuit and a battery for powering said pump via said control circuit, said audible alarm device transmitting at least one voice message to said patient upon said control circuit detecting a predetermined state of operation of said pump and/or battery.

8. An audible alarm device operably connected to a control circuit for monitoring and controlling the operation of a battery powered blood pump disposed within a patient, said alarm device and said control circuit both disposed within a portable housing external of said patient, said audible alarm device transmitting at least one voice message in the vicinity of said patient upon said control circuit detecting a predetermined state of operation of said pump.
