New light-sensitive material could eliminate some of the endoscopic procedures needed to remove gastrointestinal devices
A variety of medical devices can be inserted into the gastrointestinal tract to treat, diagnose, or monitor GI disorders. Many of these have to be removed by endoscopic surgery once their job is done. However, MIT engineers have now come up with a way to trigger such devices to break down inside the body when they are exposed to light from an ingestible LED.
The new approach is based on a light-sensitive hydrogel that the researchers designed...
