Cardiovascular Sensing

�A strong need for continuous, non interfering blood pressure measurements: Ambulatory Blood Pressure Measurements (ABPM)

�No current commercial productsatisfies this need

�Hypertension affects 25% of the worlds population

�1 in every 8 deaths is due to uncontrolled hypertension

�First product focus is non-interfering 24 hours ABPM

Problem

Technology

Product

� A disposable patch

�Miniaturized electronics for excitation, collection, processing, storage and transfer/ transmission of data

� Optional reader (transceiver) device

� Dedicated software

� A 510 (k) is most likely adequate (according to an independent US consultant)

�Distension from impedance sensing

� Arterial dimensions by multifrequency excitation: permittivity and conductivity of different tissues exhibit different frequency dependencies

� Arterial stiffness from pulse wave velocity

�Differential pressure from distension and stiffness

� Absolute pressure from functional relation: vessel diam. vs. pressure

� Distension

� Stiffness

� No counter pressure

� The method is model based!

� No wire – or hose – connections to external devices

� Disposable patch: no cross-contamination

Why is this not common practice?

�Because arterial distension is (has been) difficult to measure and

�Arterial stiffness has been almost impossible to measure at a single location
