 The last time you were sick, the doctor probably used this to check your heartbeat. But using a stethoscope is not as easy as it may look. It is often a challenge to identify the meaning behind different types of heart sounds. But three Cal students got together and created a device that could solve this issue. This is the Echo Core, and it has the power to turn a normal analog stethoscope into a digital stethoscope that does much more than just check heart sounds. The Echo Core is the latest product of Echo Devices, a startup founded by recent Cal grads Connor Landgraf, Tyler Crouch, and Jason Bellitt. Echo Devices is a startup medical device company in Berkeley, California. We came out of Berkeley and came out of the skydeck incubator here, and we built a smartphone connected stethoscope. We built a component that fits onto the analog stethoscope and then sends all the heart sound data to a physician's smartphone or tablet. Connor's inspiration stemmed from working on his senior thesis at Cal. My professor brought in half a dozen physicians and had them talk to us about their experiences with medical devices. And one of the things that they said was that we don't feel confident in our ability to use the stethoscope. And that was just kind of completely shocking to me that they didn't feel like this device had much value to them and that it takes so much time to learn and get good at. And so I thought, you know, we have apps like Shazam that can identify music and crowded Starbucks. Why can't we do the same thing for heart sounds? And that was the inspiration. Within seconds, a regular analog stethoscope can be turned into a more efficient health care device with the attachment of the Echo Core. You have the Echo Core now attached. Connect your piece, put it on the top, like that. The Echo Core allows a physician to record a patient's heartbeat, which can then be played back on a smartphone for analysis. This analysis can then be shared with cardiologists, instantly connecting medical practitioners around the world. We can achieve kind of the triple aim of health care and that is that we can make it less expensive, we can provide better quality of care and we can provide better coordination of care. With the device, we can have a nurse assistant take a patient's heart sound and record it on their smartphone and then share it with another cardiologist at Stanford of Johns Hopkins, thousands of miles away, all from their smartphone and all in almost real time. Connor credits Echo device's success to his education and experiences at Cal. When you're surrounded by people who are driven and energetic and intelligent and really passionate about changing the world in whatever way they can, that's bound to rub off on you. And I think more than classes and textbooks and all the problem sets that I did, it was the students and inspiring stories and visions that they had that played such a big role in my life. From a senior thesis to an established company credited with the potential to revolutionize health care diagnostics, Echo devices is certainly on its way to changing the world of medicine.
