Abstract
A system for non-invasively monitoring one or more physiological parameters such as pressure and/or pressure gradients in a cardiac conduit adapted for blood bypass flow. The system includes the conduit, at least one sensing device chronically located within the conduit, and a non-implantable readout device. The sensing device includes at least one inductor coil and at least one sensor for monitoring the one or more physiological parameters for diagnosis of the condition of the conduit after the conduit is implanted in a patient. The readout device includes at least one inductor coil allowing electromagnetic telecommunication and electromagnetic wireless powering of the sensing device through the inductor coil thereof.
