Tethered capsule endomicroscopy

Massachusetts General Hospital researchers have created a new kind of endoscopy device that resembles a large plastic vitamin capsule on a tether and can generate 3D microstructural images of the upper GI tract.¹ As proof of concept, the team used the device to image Barrett's esophagus in patients. The technology is licensed to NinePoint Medical Inc.
