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
