Video is the world’s smallest pacemaker that is smaller at a rice grain

• Has developed the world’s smallest pacemaker that can be injected into the patient’s body and controlled by light
• The newly developed pacemaker wireless is just one millimeter thick and 3.5 millimeters long
• Pacemakert is nourished by a so -called galvanic cell that uses the body of the body to convert chemical energy into electrical impulses and stimulate the heart
• It is estimated that the new pacemakert can be tested on people within two to three years

Millions of people worldwide have a permanent pacemakere that stimulates electrical impulses a heartbreakto beat it normally. The American -led research team behind the new tool said their goal was to help one percent of children born with congenital heart problems, who needed a temporary pacemaker during the week after surgery. Pacemaker can also help adults restore normal heartbeat when they recover after heart surgery – writes Sciencealert.

No need to surgery

Currently, temporary pacemakers need to sew electrodes with surgical intervention on myocardial muscles, which are connected to wires on the patient’s chest. When the pacemaker is no longer required, doctors or nurses pull out the wires, which can sometimes cause injuries. Neil Armstrong, the first man on the moon, died in internal bleeding after removing his temporary pacemaker in 2012.

However, the newly developed pacemaker is wireless, only one millimeter thick and 3.5 millimeters long, fits in an injection needle. It is designed that if it is no longer needed, it will dissolve in the body, saving patients from invasive intervention, said John Rogers, head of Bioelectronics Development at Northwestern University On the University’s Newsletter.

Light tells you what heartbeat should be stimulated

The pacemakert is paired with a soft patch worn on the patient’s chest. When the patch is irregular heartbeat It detects, automatically flashes a light that tells the pacemaker what heartbeat you need to stimulate – reads in Nature published in Nature in a studyin which Rogers et al.

Pacemakert is a so -called galvanic cell nourishwhich uses the body of the body to convert the chemical energy into electrical impulses that stimulate the heart. According to the study, pacemaker has so far worked effectively during laboratory tests on mice, rats, pigs, dogs and human heart tissue.

Rogers told AFP that he estimates that the pacemakert could be tested on humans within two to three years. He added that his laboratory had launched a startup company to achieve this goal. In the future, the technology, which is based on the new tool, can « create unique and powerful strategies to deal with human health social challenges, » he said.
