Form and function
The Mi-eye2 is a wide-angle camera in a disposable needle with a USB-connected tablet meant to diagnose joint injuries without an MRI.
After numbing a patient’s knee, shoulder, or other joint, a surgeon inserts the 0.09-inch Mi-eye2 needle.
Video from the camera shows a 120-degree view of the interior of the joint on the tablet, allowing the surgeon to spot tears and other injuries.
O’Donnell founded Trice Medical in 2011 with engineer Richard Washburn and a group of orthopedic surgeons. The company was incubated at BioStar Ventures, where O’Donnell had been a managing partner.
Trice has raised about $22 million for Mi-eye2, its only product, from venture capital firms and individual investors.
The FDA-cleared Mi-eye2 is meant for orthopedic surgeons. The imaging system sells for $495, and the tablet rents for $250 a month.
Competing in-office orthoscopic systems are bulkier, with thicker, nondisposable needles and bigger processors, and typically display only a 75-degree field of view.
Trice plans to launch Mi-eye2 internationally in the second half of 2017. Nirav Amin, an orthopedic surgeon and professor of sports medicine and knee reconstruction at Loma Linda University Medical in Loma Linda, Calif., says the device’s size puts his patients at ease and the disposable needles reduce infection risk. “It’s a fantastic new product,” he says.
