ARTICLE SUMMARY:
Esperto Medical uses resonance sonomanometry to noninvasively and continuously deliver clinically meaningful blood pressure data—while simultaneously generating a unique cardiac data set poised to drive new discoveries.
Noninvasive continuous blood pressure monitoring is poised to become the next major leap in cardiovascular care, thanks to the deep clinical insight that continuous data can provide. Blood pressure is among the richest predictors of stroke, heart failure, kidney damage, and other vascular disorders—yet the traditional tools we use to measure it are surprisingly limited.
Today’s cuff-based devices, whether used in clinics or at home, offer only a single snapshot of a vital sign that fluctuates constantly with sleep, stress, meals, posture, medication timing, exercise, illness, and even with each heartbeat. A single reading can easily miss a dangerous spike or dip.
Several companies are pushing toward continuous, cuff-less blood pressure monitoring. Aktiia and Biobeat, for example, have already received FDA clearance for noninvasive devices: Aktiia with an optical sensor and photoplethysmography (PPG)-based algorithm, and Biobeat with a reflective PPG sensor and pulse wave transit time, which measures the time a pulse wave takes to travel between two points. Both of these devices measure proxies for blood pressure and require calibration to cuff-based measurements.
These consumer technologies provide valuable trend data, yet they remain less clinically accurate than the gold standard: invasive arterial catheterization performed in hospitals. Because invasive monitoring is impractical for most patients who could benefit from continuous data, early-stage CoraVie Medical is developing an implantable sensor intended to do for blood pressure what continuous glucose monitors have done for diabetes.
Esperto Medical believes it can go further, enabling clinically relevant, noninvasive continuous monitoring from something as simple as a smartwatch band. Its underlying technology, resonance sonomanometry (RSM), introduces a novel physics-based approach to determining blood pressure.
