Abstract :
We present the design and realization of a novel magnetic sensor system for in situ monitoring of cardiovascular parameters, such as arterial distension and pulse. The system is designed as an implantable, extravascular magnetic field sensor for continuously measuring these parameters. It is wrapped around an arterial blood vessel without constricting the artery, thus avoiding stenosis. In vitro measurements on silicone tubes show the predicted linear elastic properties. Successful in vivo experiments detect the viscoelastic behavior of real blood vessels and its correlation with blood pressure.
