BEIJING, April 24 – Researchers presented a batteryless pacemaker yesterday that generates their energy from the heartbeat of pigs in what can pave the way for an “implant for life” in people suffering from heart defects.

Millions of patients rely on pacemakers – small electrical implants in the abdomen’s chest – to help regulate their heartbeat after chronic or acute illness.

Even with the latest technological advances, pacemaker batteries can be stiff or bulky and may need to be replaced several times over a lifetime.

Energy harvesters, which generate electricity from pulses sent by the body, have been shown to be effective in recent years, but only in small animals such as rats, as well as low energy cell models.

Now researchers in China and the United States believe that they have successfully tried a self-propelled pacemaker in adult pigs – an animal strangely physiological sim

The selected animals suffered from irregular heartbeats similar to patients with pacemakers.

The team developed an implantable generator that sits on the surface of the heart and bends with each heartbeat and thereby generates electricity from kinetic energy.

“(the pacemaker) was completely implanted in adult pigs and all energy for cardiac pacing is recovered from the same heart’s heartbeat energy,” Zhou Li, from the Chinese Academy of Sciences and lead student writer, told AFP.

When they opened the units, they found that the irregular heartbeat of the swine was corrected.

Furthermore, the energy retained from each heartbeat was higher than the energy requirement of most human pacemakers, opening the door to one day, giving patients a permanent source of power for their implants.

“It may be an” implant for life, “says Zhou.” This is our goal and the ultimate goal of scientific research in the field. “

However, the team stressed that more work was needed to determine the security of the entities and long-term durability before male versions could be developed

Zhou said self-propelled technology could have a variety of applications in areas such as self-loading devices and “smart” clothing.

Tim Chico, professor of cardiovascular medicine and honorary consulting cardiologist, University of Sheffield, which was not involved in the research, the experiment called “very encouraging.”

“This study was conducted in pigs whose hearts are as large as humans and are often used to test devices or treatments before use in humans,” he said. 19659005] The study was published in the journal Nature Communications – AFP-Relaxnews
