Abstract

A holding device having an integrated charging coil assembly for an Implantable Medical Device (IMD) is disclosed which includes a pouch for carrying a controller/charger external device for the IMD. The charging coil assembly includes a charging coil and optionally a battery for providing power for driving the charging coil to produce a magnetic charging field for the IMD. The charging coil assembly is connected to a cable also integrated with the holding device, which cable terminates at a connector. The connector is proximate to a port on the controller/charger when inserted into the pouch, and thus can be connected thereto. When so connected, the controller/charger will automatically control the charging coil assembly to produce the magnetic charging field without further input by the patient or the need to access the Graphical User Interface (GUI) of the controller/charger.

Claims

1. A charging system for an implantable medical device (IMD), comprising:

a holding device wearable by a patient having an IMD, the holding device configured to hold an external device;

a charging coil assembly integrated within the holding device, comprising;

a charging coil configured to generate a magnetic charging field for the IMD, and

a connector; and

the external device comprising a port, wherein the external device is configured to;

provide a user interface to allow a patient to control and/or monitor the IMD, and

automatically generate the magnetic charging field when the connector is coupled to the port.

2. The system of claim 1, wherein the charging coil assembly further comprises a cable between the charging coil and the connector.

3. The system of claim 1, wherein the holding device comprises a belt or collar.

4. The system of claim 1, wherein the holding device is configured to hold the external device at a pouch.

5. The system of claim 4, wherein the pouch is affixed to the holding device.

6. The system of claim 4, wherein a position of the pouch is adjustable along a length of the holding device.

7. The system of claim 1, wherein the charging coil assembly comprises a housing.

8. The system of claim 7, wherein the housing comprises a second battery for powering the generation of the magnetic charging field.

9. The system of claim 7, wherein the housing further comprises the charging coil.

10. The system of claim 8, wherein the external device comprises a first battery.

11. The system of claim 1, wherein the external device is configured to provide the user interface to allow a patient to control and/or monitor the IMD when the connector is not coupled to the port.

12. The system of claim 1, wherein the external device is additionally configured to provide the user interface to allow a patient to control and/or monitor the IMD when the connector is coupled to the port.

13. The system of claim 1, wherein the connector and port are Universal Serial Port based.

14. The system of claim 1, wherein the external device further comprises an antenna to allow the patient to control and/or monitor the IMD.

15. The system of claim 14, wherein the antenna comprises at least one coil.

16. The system of claim 14, wherein the antenna comprises at least one short-range RF antenna.

17. The system of claim 1, wherein the external device further comprises detection circuitry configured to detect when the connector is coupled to the port, and wherein the detection circuitry instructs control circuitry in the external device to automatically generate the magnetic charging field when the connector is coupled to the port.

18. The system of claim 1, wherein the system further comprises an amplifier to drive the charging coil to generate the magnetic charging field.

19. The system of claim 18, wherein the external device further comprises a first battery, and wherein the first battery is configured to provide power to the amplifier.

22. The system of claim 21, wherein the amplifier is located within the integrated external controller/charger.

23. The system of claim 21, wherein the amplifier is located within the charging coil assembly.

24. The system of claim 18, wherein the external device further comprises a first battery, and wherein the charging coil assembly further comprises a second battery, and wherein the second battery is configured to provide power to the amplifier.

25. The system of claim 1, wherein the external device further comprises demodulation circuitry configured to receive data telemetry from the IMD when the magnetic charging field is being produced.

26. The system of claim 1, wherein the charging coil assembly further comprises demodulation circuitry configured to receive data telemetry from the IMD when the magnetic charging field is being produced.

27. The system of claim 1, wherein the external device is further configured to automatically determine the charging coil assembly coupled to the port from a plurality of different charging coil assemblies coupleable to the port and integratable within the holding device, and to automatically control the magnetic charging field in accordance with the determined charging coil assembly.

28. The system of claim 1, wherein the user interface of the external device comprises a graphical user interface.

29. The system of claim 1, wherein the external device is configured to automatically generate the magnetic charging field when the connector is coupled to the port and without receiving input from the user interface.
