Abstract

A system and method for the intra corporal, telemetric measuring of blood pressure, particularly within the heart or a great vessel, includes a substantially rigid sensor chip mounted in a holder and an antenna. The holder is anchored within an appropriate location in the cardiovascular system, such as in the cardiac septum, via a catheter or other minimally-invasive procedure to position at least one capacitive pressure sensor on the chip in the blood flow to be sensed. Measured values are transmitted telemetrically from the chip to an extra corporal monitoring device.
