Abstract
A method and a device for the non-invasive determination of blood flow and associated parameters in arteries, in particular the arterial waveform and the blood pressure. According to said method, a sensor having at least one deformable contact portion is placed on a tissue surface, essentially over an artery, and the contact portion is subjected to a temporally variable and defined external force, F(t). The deformation of the contact portion by the blood flow inside the artery in response to said force F(t) is measured.
