Abstract

In an implantable intravascular pressure determining device and method, a pressure sensor generates a raw pressure signal, an acceleration sensor generates an acceleration signal, and an evaluation unit determines a disturbance pressure signal from the acceleration signal. A processed signal is generated as the difference between the raw pressure signal and the disturbance pressure signal. The processed signal corresponds to intravascular pressure.
