Method of power and data transfer in implantable electronic devices

摘要

A system for transferring data and power between electronic devices implanted in a patient is described. The system comprises a first unit and a second unit that in use are both implanted in the patient and a cable connecting the first unit and the second unit. The first unit comprises a current supply unit that supplies a selected current output to the second unit via the cable and a processor configured to anticipate an action to be performed by the second unit and to select the current output dependent on the anticipated action.

1. A system for transferring data and power between electronic devices implanted in a patient, the system comprising:
a first unit and a second unit that in use are both implanted in the patient; and a cable connecting the first unit and the second unit, wherein the first unit comprises: a current supply unit that supplies a selected current output transferring data and power to the second unit via the cable, wherein the current output is a square current waveform having intermittent transitions of polarity that encode the data as a series of pulses; and a processor configured to anticipate an action to be performed by the second unit and to select the current output dependent on the anticipated action and wherein the second unit does not comprise a discrete capacitor.
