Abstract

A transcutaneous charging device for charging an implant comprising:

• • a power input;
  • a conversion circuit to convert power from said power input to transcutaneously charge said implant;
  • a control; and
  • an indication element;
  • wherein said control is programmed to initiate an indication using said indication element when it is time to charge said implant.

Claims

1. A transcutaneous charging device for charging an implant comprising:

a power input;

a conversion circuit to convert power from said power input to transcutaneously charge said implant;

a control located in said transcutaneous charging device; and

an indication element;

wherein said control located in said transcutaneous charging device is programmed to initiate an indication to charge said implant, using said indication element, said initiating an indication by said control located in said transcutaneous charging device being performed before said implant is charged,

the charging device further comprising a wireless receiver and wherein said indication is stopped after deploying said charging device and receiving a signal from said implant by said wireless receiver;

said device further comprising a sensor configured to detect a signal associated with a distance between said charging device and the implant, said charging device configured to initiate transfer of charge to the implant when the signal associated with the distance indicates a distance which is less than a preselected distance;

said sensor additionally configured to detect a positioning of said charging device relative to the implant, said control configured to at least one of increase a current in said conversion circuit and increase a charging time in response to said sensor detecting that a positioning of said charging device relative to the implant is not optimal.

2. A device according to claim 1, wherein said indication is initiated periodically.

3. A device according to claim 1, wherein said indication is initiated on specific dates.

4. A device according to claim 1, wherein said indication, when activated, is continuous.

5. A device according to claim 1, wherein said indication, when activated, is intermittent.

6. A device according to claim 2, wherein said signal received from said implant by said wireless receiver is supplied by said implant after it is recharged.

7. A device according to claim 1, wherein said indication element comprises a display, an audio transmitter, and a mobile telephone transmitter.

8. A device according to claim 1, comprising a battery backup.

9. A device according to claim 1 wherein said indication gives an indication of a charge status of a battery in the implant.

10. A device according to claim 1 wherein said indication element gives an indication to a user that it is time to charge the battery.

11. A device according to claim 1, wherein said charging device is configured to charge said implant while being shielded from direct contact with a user.

12. A device according to claim 1, wherein said deploying includes placing said charging device on a patient'"'"'s skin facing the implant.

13. A device according to claim 1, wherein said deploying includes placing said charging device on a patient'"'"'s skin as close as possible to the implant.

14. A device according to claim 1, wherein said charging device is configured to give an indication to the implant, said indication including a query for information related to the implant.

15. A device according to claim 14, wherein said information is selected from a charge level of a battery in the implant and a temperature inside the implant.

16. A device according to claim 1, wherein said charging device is configured to give an indication to said control.

17. A device according to claim 16, wherein said indication to said control is related to a non-optimal position of said charging device relative to the implant.

18. A device according to claim 1, wherein said implant is configured to give an indication of at least one of the temperature of said implant and a temperature of skin of a user.

19. A device according to claim 1, said control additionally configured to initiate an indication that the positioning of said charging device relative to the implant is not optimal.

20. A device according to claim 1,wherein said control is configured to receive a signal from the implant and is configured to actuate said indication element to provide an indication to charge said implant, using said indication element.
