LEDs used in tests to replace invasive medical procedures

Researchers produce gadgets such as gastric balloons that break down when lit by swallowable lights

The days of needing to have medical devices removed through an invasive procedure could be numbered. Researchers have produced gadgets such as gastric balloons that break down when light from a swallowable LED shines upon them.

The team say the approach could be extended to a broader range of medical equipment, as well as offering a new approach to delivering drugs to the right location at the right time.
