David Narrow has created substantial waves as an entrepreneur in the field of healthcare. At the mere age of 25, he is the CEO of Sonavex and creator of EchoMark and EchoSure.
David’s career with Sonavex began when he noticed that doctors would often have trouble locating previous surgical sites on patients. Locating these surgical sites is crucial for doctors if they are performing a follow-up procedure on a site. Usually the sites would be marked with implants that could be viewed later with an ultrasound. However, the implants that were currently being used were often difficult to accurately pinpoint in the ultrasounds. David realized that the healthcare industry needed a better implant that could be more easily seen and located with an ultrasound. So he started Sonavex and designed EchoMark.
EchoMark is a surgical implant made from a polymer material that is harmless to the human body. At the end of surgery, a doctor can insert EchoMark into the surgical site to mark it for later procedures. EchoMark’s unique shape causes the sound waves of an ultrasound to bounce off of it at multiple angles, enabling doctors and nurses to distinguish its location more quickly and accurately than previous surgical markers. If a second surgery in the area is not needed, EchoMark dissolves within 18-24 months after insertion, without needing to be removed. David’s product aptly filled an important need in healthcare, but it wasn’t long before he found a new need to tackle.
Another problem that medical professionals face is the occurrence of blood clots in patients who have undergone any surgical procedure in which veins or arteries are reconnected. Over 550,000 patients per year experience this type of surgery, which always involves the risk of blood clots. If a clot occurs and is not diagnosed and treated quickly, the patient may experience serious harm and have to undergo even more extensive surgeries. In response to this problem, David designed EchoSure, an ultrasound system that monitors patients’ newly connected blood vessels for clots. The system automatically alerts medical personnel of flow loss in a vessel. EchoSure’s intuitive interface allows medical professionals to use it without needing any training in ultrasound. As such, EchoSure acts as an early warning system against blood clots, allowing for rapid diagnosis and treatment before they can cause substantial damage.
David Narrow’s creativity and innovation to solve problems in healthcare have benefited numerous patients and have paved the way for even more valuable technology.
