摘要
The invention refers to a medical implantable device having a data communication interface and a pulse generator. The data communication interface is operatively connected to the pulse generator. The pulse generator is configured to generate and deliver forward current pulses and reverse current pulses, wherein a polarity of the reverse current pulses is opposite to the polarity of the forward current pulses. The generator is controlled by the data communication interface and the data communication interface together with the pulse generator are configured to generate pulses representing binary digits, wherein a first kind of digits (1 or 0) is represented by a current pulse, and the respective other type of binary digits (0 or 1) is represented by a pause between current pulses. The data communication interface together with the pulse generator are configured to deliver current pulses with strictly alternating polarity so that every other current pulse is a reverse current pulse of opposite polarity compared to an immediately preceding forward current pulse. Thus, every string of current pulse is both, charge balancing and information encoding.
