Founded by acoustics and ultrasound expert Alan Winder, Sonogen Medical develops advanced ultrasound devices for bone-fracture healing. Based in Baltimore’s Launchport medical-device incubator, the company pairs a portable 20-minute-per-day treatment device with ultrasound-based monitoring that lets patients and caregivers follow healing progress. Its technology grew from Winder’s decades of sonar and medical-ultrasound research, including work that helped commercialize an earlier ultrasonic bone-healing device.
