Abstract

A system and method allows a physician to remotely change the settings of a medical device that is implanted in a patient who is physically separated from the patient. The physician uses a computer to remotely access the patient'"'"'s computer and programs new settings for the medical device that is conveyed to an emulator which in turn conveys the settings to the medical device. Patients who have neurostimulators implanted in them are particularly suited to receive the benefits of the present invention.

Claims

1. A system for remotely programming a medical device comprising:

a medical device, the medical device operating on a patient in accordance with one or more settings;

a first computer, the first computer comprising a first communications interface;

an emulator, the emulator being coupled to the first computer and comprising a second communications interface for communicating with the medical device; and

a second computer, the second computer comprising a third communications interface for communicating with the first computer via the first communications interface, wherein the second computer can access the one or more settings of the medical device.

2. The system of claim 1, wherein the medical device is implanted in the patient.

3. The system of claim 1, wherein the first computer comprises a memory, the memory storing a program for accessing the one or more settings of the medical device.

4. The system of claim 3, wherein the program comprises a review procedure for reviewing the one or more settings of the medical device and a programming procedure for modifying the one or more settings of the medical device.

5. The system of claim 1, wherein the second communications interface comprises a radio frequency interface.

6. The system of claim 1, wherein the first computer and second computer communicate via the Internet.

7. The system of claim 1, wherein the first computer and second computer communicate through a dedicated communications link.

8. The system of claim 1, wherein the medical device comprises a neurostimulator.

9. The system of claim 1, wherein the one or more settings include at least one of a stimulation signal pulse width, a stimulation signal rate, a stimulation signal amplitude and an electrode parameter.

10. The system of claim 1 comprising a feedback component coupled to the first computer for capturing a condition of the patient.

11. The system of claim 10, wherein the feedback component including one of a camera and a biosensor.

12. A method of remotely programming a medical device comprising the steps of:

remotely accessing a first computer located proximate a patient by a medical practitioner using a second computer in electronic communication with the first computer;

inputting a change in one or more settings of a medical device implanted in the patient into the second computer;

communicating the change in the one or more settings from the first computer to an emulator connected to the first computer;

transmitting the change in the one or more settings from the emulator to the medical device.

13. The method of claim 12, wherein the step of transmitting comprises transducing a digital signal into an analog signal.

14. The method of claim 13, wherein the analog signal is a radio frequency signal.

15. The method of claim 12, wherein the step of remotely accessing is performed through a remote access program.

16. The method of claim 12, wherein the step of inputting includes initiating a programming sequence.

17. The method of claim 12, comprising performing a review sequence which includes:

selecting a review request at the second computer;

communicating the review request to the emulator via the first computer;

transmitting a review request signal from the emulator to the medical device;

transmitting one or more settings from the medical device to the emulator; and

communicating the one or more settings to the second computer via the first computer.

18. The method of claim 12, wherein the medical device includes a neurostimulator.

19. The method of claim 12, wherein the one or more settings include at least one of a stimulation signal pulse width, a stimulation signal rate, a stimulation signal amplitude and an electrode parameter.

20. The method of claim 12, comprising:

capturing patient feedback at the first computer; and

communicating the patient feedback to the second computer.

21. A system for remotely programming a medical device comprising:

a first computer, the first computer comprising a first communications interface;

an emulator coupled to the first computer and comprising a second communications interface for communicating with a medical device; and

a second computer, the second computer comprising a third communications interface for communicating with the first computer via the first communications interface, wherein the second computer can access one or more settings of the medical device through the emulator.

22. The system according to claim 21, wherein the medical device is an implanted neurostimulator.

23. A system for remotely programming a medical device comprising:

a transceiver component; and

a control component coupled to the transceiver component;

wherein the transceiver component converts control signals from the control component into a programming signal compatible with a medical device, the programming signal generated as a function of input to the control component from a first computer executing a computer executable code, the computer executable code

processing an instruction to change at least one setting of the medical device, the instruction received from a second computer physically remote from the first computer; and

generating the control signal for the medical device, the control signal being transmitted to the control component.

24. The system of claim 23, wherein the computer executable code further includes processing data signals received from the medical device via the transceiver component.

25. The system of claim 23, wherein the transceiver component includes an RF head.

26. The system of claim 23, wherein the control component includes a signal processor, a count generator and a program sequence generator.

27. The system of claim 26, wherein the signal processor amplifies and integrates the electrical signals.

28. The system of claim 26, wherein the count processor generates a plurality of counts using the electrical signal.

29. The system of claim 23, wherein the transceiver component and the control component have an integrated construction.

30. The system of claim 23, wherein the control component is connected to the first computer through one of a serial port, a parallel port and a PCI interface.

31. The system of claim 23, wherein the medical device is an implanted neurostimulator.

32. The system of claim 29, wherein the at least one setting includes one of a stimulation signal pulse width, a stimulation signal rate, a stimulation signal amplitude and an electrode parameter.
