Abstract

The present invention is directed to a self contained control patch for an implanted medical device, comprising a housing capable of being removably associated with an external surface of a patient, a transmitter for transmitting at least one of a transcutaneous power signal and a transcutaneous control signal to an implanted device; and a pre-programmed storage device containing at least one control program, wherein the control program dictates the nature of the signal from the transmitting means. Additionally, the present invention is directed to a system of such patches comprising two or more patches, with each patch being pre-programmed with a discrete set of instructions. Methods for using the patches are additionally disclosed.

Claims

means for transmitting at least one of a transcutaneous power signal and a transcutaneous control signal to an implanted device;

a pre-programmed storage device containing at least one fixed control program, wherein the fixed control program dictates the nature of the signal from the transmitting means; and

a power source for providing operational power to at least one of the transmitting means and the storage device.

2. The patch according to claim 1, wherein the transmitting means comprises an RF transmitter, wherein the fixed control program dictates at least one of the frequency and amplitude of the RF signal.

3. The patch according to claim 1, wherein the transmitting means comprises a conductive coil, the conductive coil being coupled with a conductive coil associated with the implanted device so as to allow the inductive transfer of power from the transmitting means to the implanted device, the fixed control program dictating the flux of the electric field through the coil in the implanted device.

4. The patch according to claim 1, wherein the transmitting means comprises means for transmitting only a power signal to an implanted device.

5. The patch according to claim 1, wherein the transmitting means comprises means for transmitting only a control signal to an implanted device.

6. The patch according to claim 1, wherein the transmitting means comprises means for transmitting both a transcutaneous power signal and a transcutaneous control signal to an implanted device.

7. The patch according to claim 1, additionally comprising means for attaching the housing of patch to a patient.

8. The patch according to claim 7, the attachment means comprising an adhesive associated with at least a portion of the housing.

9. The patch according to claim 7, the attachment means comprising a bandage material having an adhesive thereon, the housing being associated with the bandage.

10. The patch according to claim 7, the attachment means comprising a bracelet associated with the housing.

11. A pre-programmed treatment system, comprising:

at least two self-contained control patches, each patch comprising;

a housing capable of being removably associated with an external surface of a patient;

means for transmitting at least one of a transcutaneous power signal and a transcutaneous control signal to an implanted device;

a pre-programmed storage device containing at least one fixed control program, wherein the fixed control program dictates the nature of the signal from the transmitting means; and

a power source for providing operational power to at least one of the transmitting means and the storage device.

wherein each control patch contains a separate fixed preprogrammed control program.

12. The system according to claim 11, wherein transmitting means of each patch comprises an RF transmitter, the fixed control program dictating at least one of the frequency and amplitude of the RF signal.

13. The system according to claim 11, wherein the transmitting means of each patch comprises a conductive coil, the conductive coil being coupled with a conductive coil associated with the implanted device so as to allow the inductive transfer of power from the transmitting means to the implanted device, the fixed control program dictating the flux of the electric field through the coil in the implanted device.

14. The system according to claim 11, wherein the transmitting means of each patch comprises means for transmitting only a power signal to an implanted medical device.

15. The system according to claim 11, wherein the transmitting means of each patch comprises means for transmitting only a control signal to an implanted medical device.

16. The system according to claim 11, wherein the transmitting means of each patch comprises means for transmitting both a transcutaneous power signal and a transcutaneous control signal to an implanted device.

17. The system according to claim 11, wherein each patch additionally includes an indicia, wherein the indicia indicates the content of the pre-programmed control program.

18. The system according to claim 17, wherein the indicia comprise one of the group consisting of colors, letters, roman numerals, numbers, and shapes.

19. A method for providing a control program to an implantable device, comprising the steps of:

associating a pre-programmed patch with an external portion of a patient proximate an implanted medical device;

transmitting a fixed control signal from the patch to the implanted device; and

altering the operation of the implanted device according to the fixed control signal.

20. The method according to claim 19, additionally comprises the step of programming a pre-programmed patch with a fixed, program before the step of associating.

21. The method according to claim 19, wherein the step of transmitting a fixed control signal comprises the step of transmitting a control signal containing reprogramming instructions, the step of altering the operation comprising the steps of:

reprogramming the implanted device with the reprogramming instructions; and

altering the operation of the device according to the reprogramming instructions.

22. The method according to claim 19, wherein the step of transmitting a control signal comprises the step of transmitting a fixed control signal containing a power signal, the step of altering the operation comprising the steps of:

receiving the power signal from the pre-programmed patch;

altering the operation of the device according to the characteristics of the power signal.

23. The method according to claim 22, wherein the step of transmitting comprises the step of transmitting an RF power signal, and the step of altering comprises the step of altering device operation according to at least one of the frequency and amplitude of the power signal.

24. The method according to claim 22, wherein the step of transmitting comprises the step of creating a magnetic field through a coil in the pre-programmed patch, wherein the magnetic field extends at least partially to a corresponding coil in the implanted device, the step of altering comprising the step of altering device operation according to the flux of the magnetic field through the coil in the implanted device.

25. A method for providing replaceable transcutaneous power to an implantable device, comprising the steps of:

associating an autonomously powered patch with an external portion of a patient proximate an implanted medical device; and
