Eko, a startup which emerged from University of California Berkeley’s skydeck accelerator in 2013, has received clearance from the Food and Drug Administration for its next generation stethoscope.

The device, which is now on sale, allows doctors to stream heart data to their phones and into their patient’s electronic health records.

US-based Eko secured $2m towards the start of the year in a round which was backed by the Stanford StartX Fund. Stanford’s Department of Medicine will now become the first institution to use the device as part of a pilot.

Jason Bellet, chief operating officer at Eko, said: “Doctors can now trend a patient’s heart sounds over the course of a lifetime, something that wasn’t possible before.”
