Abstract
A medical assembly, such as an artificial heart assembly, adapted to be implanted within a living subject is composed of an implantable data communications interface adapted to receive an encoded data signal from a data communications interface located outside the subject at a position remote from the medical assembly. The encoded data signal is transmitted in a plurality of periodic signal bursts, which are transmitted at a first frequency to represent a first data value and a second frequency to represent of second data value. Each of the bursts comprises a plurality of signal transitions having a third frequency greater than both the first and second frequencies.
