The innovative device – plus tiny – is inserted with a syringe. It is no longer necessary surgery to take it out.
And the smallest pacemaker in the worldis activated by light, can revolutionize heart care, bioabsorbable, is ideal for newborns and postoperative patients…
There are many promises brought by this innovative device conceived and realized by engineers and cardiologists at Northwestern University.
Pacemaker has only 1.8 mm wide and 3.5 mm long. AND smaller than a grain of rice.
Is injected directly into the body through a syringe.
Unlike traditional pacemakers, it is activated by impulses of luz Issued by a portable, smooth and flexible device placed in the patient’s chest.
These investigators had already created a dissoluble pacemaker the size of a coin. But the need for an internal antenna limited miniaturization. This new model replaces radio frequency technology with a light -based activation system and uses a galvanic cell – a battery powered by body fluids – rather than bulky external energy sources.
When the system detects an irregular heartbeat, it emits light infrared Through the skin, activating the pacemaker and triggering electrical stimulation, explains the university.
The device is totally bioabsorvable – That is, when it is no longer necessary for the patient, naturally dissolve in body fluids after this temporary use. Stop surgery to take it off.
They are like this (very) diminished os risks Associated with conventional temporary pacemakers: infections, internal bleeding and heart muscle damage caused by the removal of implanted wires.
In preclinical studies with animals and human hearts of donors, the tiny Pacemaker has shown to be as effective as conventional devices. Its small size allows you to deploy multiple units in the heart, facilitating synchronized stimulation and even integration with other implants, such as cardiac valves replaced by catheter.
The smaller the device, the easier the deployment and the lower the risk. Also, as there is no surgery removal, medical care is much simpler.
