In order to transfer electrical energy to an implemented medical device (04) power electrodes (02) are fitted in contact with the body of a human or animal into which the medical device has been implanted. The power electrodes (02) may be directly on the skin of the body or may penetrate the skin. The implanted medical device (04) has implanted electrodes (03) which receive electrical energy via the body. To power the implanted medical device (04), a power device (01) applies an electric potential in the form of a repetitive waveform to the power electrodes (02), thereby generating an electric current in the body, and transferring electrical energy via the implanted electrodes (03) to the implanted medical device (04). Preferably the waveform is a pulsed waveform with pulses of a duration not greater than 8 žs and an inter-pulse spacing not greater than 20 žs. |
