Minimally Invasive Devices Inc. (MID) of Columbus, Ohio, has raised an additional $2.5 million from Radius Ventures, topping off its Series B financing at $11.5 million. The Series B originally raised $9 million in a financing led by Canaan Partners with participation by existing investor Charter Life Sciences. FloShield, MID’s flagship laparoscopic vision system, maintains a clear field of vision from beginning to end in laparoscopic surgery procedures. The technology easily attaches to modern HD vision systems, enabling surgery to occur without interruption, loss of vision, or scope removal for cleaning. Such removals are time-consuming, interfere with the OR team’s focus, and frequently occur during critical points in surgery when optimal vision is critical, leading to surgeon frustration. Funds will be used for sales and marketing, clinical studies, the generation of outcomes data and additional product development.
