Abstract
An apparatus and corresponding method for providing data communications to and from a location within a body cavity in which an internal transmitter receives a first data stream from an in vivo sensor, electrode, or transducer. The internal transmitter is configured and arranged to asynchronously modulate the first data stream and to provide as an output a first optical signal carrying the asynchronously modulated first data stream. The apparatus further includes an external receiver that is configured and arranged external to the body cavity such that an optical input to the external receiver is optically coupled to the internal transmitter output and receives the optical signal therefrom. The external receiver asynchronously demodulates the received optical signal and provides as an output at least one signal indicative of the first data stream.
