Cuffless, non-invasive, and self-calibrating device for accurate and ambulatory measurements of blood pressure

Unmet Medical Need:  Hypertension affects over 40% of adults and accounts for 9.4 million deaths each year, yet it remains severely under diagnosed with around 13 million U.S. adults going undiagnosed. The American Heart Association has identified the need for out-of-office blood pressure (BP) monitors to address this gap,but current devices are inadequate. Thus, there is tremendous need for a convenient method for measuring out-of-office BP.

Envisioned Healthcare Product: A device for continuous out-of-office BP measurement without a cuff for improved diagnosis and disease management. This technology incorporates external pressure compensation that improves accuracy and enables an internal calibration mechanism that eliminates the need for calibration with an external measurement.


Stage of Development: Pilot studies are being conducted comparing the performance of the novel technology with competing PTT (pulse transit time) technique.
