This is the smallest pacemaker in the world, and is implanted without surgery

They implant the smallest pacemaker in the world, without surgery

One of the consequences of increased life expectancy and the predominant lifestyle in the developed passes, is the greatest need to implant pacemaker to control the rhythm of the heart in people with cardiovascular problems.

Although the surgery necessary for this implantation is quite simple for someone experienced, it does not fail to carry the typical risks of an operation, so it would be a great relief for these patients to be able to do without such nuisance.

In addition, the need for cabling can involve a large number of complications, which is why the recent approval by the Fda of a tiny and injectable pacemaker It has aroused the joy and admiration of both patients and cardiologists.

How do conventional pacemakers work?

A pacemaker is a electronic device which is implanted through an incision below the clavicle and, from there, sends impulses to the heart to keep a normal rhythm. Once these impulses are generated, they need to be transferred through a cable, join the right ventricle of the heart through a vein.

This system of cabling it is precisely the main responsible for the negative effects of the pacemaker; since sometimes they can cause infections in the surrounding tissue, necessitating withdrawal and replacement Of the device.

How does the smallest pacemaker in the world work?

This recently approved pacemaker has been the result of a clinical trial carried out in 719 patients, of which 98% presented a great improvement in their heart rate six months later.

Developed by Medtronic,the dimensions of this device correspond to a tenth part the size of conventional pacemakers, making it much more comfortable and less bulky.

Its implantation is carried out inside a 41-inch long tube, which is injected in the groin the patient, from where he enters the bloodstream and travels to the right ventricle of the heart. Once there, it clings to the organ with some small hooks and starts producing those electrical impulses so it can beat regularly.

It only works on the lower chamber of the heart, so it is not useful in patients who need stimulation also in the upper one. In addition, it has some other contraindications, since it is not recommended for use in patients who have already had other devices implanted, and neither obese orintolerant to the materials of the device or to the heparin.

However, beyond those small obstacles, it can work well for people with atrial fibrillation and other types of dangerous arrhythmias.

Although it has not been given much use yet, it is clear that this device, free of lead, to be without a doubt a great substitute for conventional pacemakers. And it is that for something to help the functioning of the heart, it does not have to be bulky.
