Estimating the term…
A wireless charger system for inductively charging a rechargeable battery of an implantable pulse generator (IPG) implanted in a human body is provided. A charging coil in the charger is wirelessly coupled to a receiving coil of the IPG to charge the rechargeable battery. An end-of-charge (EOC) circuit continuously monitors the reflected impedance from a reflected impedance sensor and determines the end of charge when a predetermined pattern of the reflected impedance corresponding to an EOC signal from the IPG is received. Advantageously, receiving the EOC signal through the charging coil eliminates the need to provide a separate communication circuit in the IPG that communicates with the charger.
A wireless charger system for inductively charging a rechargeable battery of an implantable pulse generator (IPG) implanted in a human body, the wireless charger system comprising:
The wireless charger system of claim 2, further comprising the IPG, wherein the IPG includes an EOC switch adapted to electrically short the receiving coil to ground in a selected pattern corresponding to the predetermined pattern of the reflected impedance.
A method for a wireless charger system for inductively charging a rechargeable battery of an implantable pulse generator (IPG) that generates spinal cord stimulation signals for a human body, the method comprising:
