Patent ID: 7957804

Claim:
A device for recharging the battery of cardiac implants comprising: a generator (A) connectable and powerable by an AC or DC energy supply power source ( 1 ), at least first and second potentiometers ( 4 , 5 ), a high power amplifier ( 6 ), a transmitter unit (B) comprising a resonant network with a capacitor ( 7 ) and a coil ( 8 ), said transmitter unit (B) adapted to produce a magnetic field that induces a voltage in a corresponding coil ( 9 ) of an implantable device (C), which is rectified by a bridge rectifier ( 10 ) and filtered by a capacitor, characterized in that said first potentiometer ( 4 ) is adapted to adjust the frequency of a (co)sinusoidal voltage controlled oscillator [(cosin VCO] ( 3 ) and said second potentiometer ( 5 ) is adapted to adjust the intensity and amplitude of the (co)sinusoidal voltage controlled oscillator [(co)din VCO] ( 3 ), the resulting signal being deliverable to said high power amplifier ( 6 ) which is connected through a coaxial cable to the transmitter unit (B) whose said coil ( 8 ) is a linear air core coil, said transmitter unit (B) being adapted for producing a (co)sinusoidal magnetic field which in turn indicates a (co)sinusoidal voltage in the said corresponding coil ( 9 ) of the implantable device (C).
