Last fall, David Narrow and his colleagues reached a critical juncture in the development of their fledgling medical technology company, Sonavex. As Narrow puts it, their brainchild needed nurturing, and a suitable—and affordable—environment for it to happen in.
The company’s core concept, he says, was worth the TLC. Narrow and Johns Hopkins Hospital plastic surgeon resident Devin O’Brien Coon, who met while studying in Johns Hopkins’ biomedical engineering graduate program in the Whiting School’s Center for Bioengineering Innovation and Design, had identified a clinical problem that needed addressing. Each year, more than 550,000 people in the United States undergo medical procedures—soft-tissue reconstruction, organ transplants, bypass surgeries—in which arteries or veins are surgically connected, exposing the patient to the risk of a blood clot. Detecting the clot in a timely manner, before it blocks the vessels and leads to catastrophic complications, becomes paramount. What’s needed, Narrow says, is a real-time clot-monitoring device that can be used by nurses post-surgery.
