Medicine is constantly evolving, so researchers have developed new items that can be used in different medical fields. Some of them are gastric balloons, which have been designed to break down when they receive light from a swallowable LED. Gastric balloons could replace some invasive medical procedures in the future. Moreover, there can also be other medical applications of this method, such as delivering drugs to a desired location in the human body at a specific time. Medical personnel would be able to control the balloons through the LED. The gastric balloons are made of a hydrogel and can be devised to survive or break down in different environments. Researchers carefully select the wavelength of the light so that the surrounding tissues would stay intact. Light-degrading materials have been used prior to this method, and the use of a controlled trigger, which can pass through the body, can open the door to new possibilities. One of the greatest benefits would be the opportunity for doing non-invasive surgeries.
