Abstract:
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.
