A Charlotte-based medical devices company raised $27.6 million in a private stock offering, according to a Securities and Commission filing.

Bardy Diagnostics filed the Form D on Oct. 12. It did not disclose what it intends to do with the proceeds.

Founded in 2013, Bardy Diagnostics is a medical device start-up developing an ambulatory ECG monitor.

Its president and CEO, Jon Hunt, is also founder and managing director at Wyn River Ventures, an early growth venture capital firm investing in life science and IP wealthy companies.

Companies relying on a Reg D exemption do not have to register their offering of securities with the SEC, but they must file what’s known as a Form D electronically with the SEC after they first sell their securities.
