According to its own information, an American research team has developed the smallest pacemaker in the world. The wireless device is smaller than a rice grain and, if it is no longer necessary, can easily dissolve in the body.
Millions of people worldwide wear permanent pacemakers who stimulate the heart with electrical impulses and ensure that it is normal. Until now, the electrodes of temporary pacemakers have been sewn on the heart muscle. The cables of the device are attached to the patient’s chest. If the pacemaker is no longer necessary, medical staff must remove the cables, which can lead to injuries.
The American astronaut Neil Armstrong, the first person on the moon, died of inner bleeding in 2012 after his temporary pacemaker was removed. Such complications may no longer occur with the newly developed Pacemaker.
Help for children with a congenital heart defect
It can take another two to three years before the new pacemaker is tested for people, student author John Rogers from Northwestern University told the AFP press office. His colleague Bozhi Tian from the University of Chicago, who was not involved in the project, spoke about a “breakthrough” that could also initiate progress in other areas of medicine. Their goal is to help children who trust a temporary pacemaker with a congenital heart defect a week after surgery, the scientists involved in explaining the development.
