The sharp ends of an injection needle are sources of fear for many people, experts may have discovered a solution to that woe.
Pea-sized devices containing needles could potentially deliver medicine via gut passages while avoiding painful invasive procedures. The needle-loaded capsule is ingested, which embeds upon the stomach lining where there are minimal pain receptors.
The method proved harmless in an early experiment with pig subjects, but further studies are required in determining long-term effects.
Medical researchers are considering the use of the device for the treatment of diabetics and cancer patients, who require the administration of injection throughout their lifetimes.
