Successfully implanted wireless pacemaker

For the first time in the world, small tablet-sized wireless pacemakers have been implanted into patients' bodies in the UK, with initial results being effective and safe. The operations described as an important milestone can revolutionize the treatment of arrhythmias and minimize the risk of using current pacemakers.

This is part of a trial of wireless pacemakers deployed throughout Europe. The new device, called Micra Transcatheter Pacing System, was developed by Medtronic, a US company, and is about one-tenth the size of current devices.

Professor John Morgan of Southampton General Hospital (UK) said, this mini meter is implanted in the patient's heart through an intravenous catheter. These simple activities take only 10 minutes and patients can recover normally in just 2-3 days instead of 6 weeks as before. Because there is no need for transplant surgery, this procedure will reduce the risk of infection that could lead to death.

According to Professor Morgan, a pacemaker is available 70 years ago and has been continuously improved, providing excellent treatment results, helping to save countless patients. However, its drawback is that the texture is cumbersome and can be removed from the implanted site (next to the heart), affecting the function of operation, even if there is an operation to re-implant.

Therefore, the successful development of a new compact and straightened cardiac pacemaker is a major step in the treatment of arrhythmias when it virtually eliminates the limitations of old devices.
