Scientists develop the smallest heartbeat in the world and the size of a rice

Northwestern University researchers developed an unusually normal heartbeat It promises a revolution in heart treatmentsEspecially for the most vulnerable patients.

The new device, Smaller than a riceIt represents a great progress in medical miniaturization. Its low size allows unusually (with a width of only 1.8 millimeters, 3.5 millimeters and a thickness of 1 mm) in the body through an expanded method.

John A. Rogers: “We have developed what, according to our knowledge, is the smallest crowd of heartbeat in the world.” Pioneer Northwest and commander of devices development. “There is one The crucial need for a temporary cardiac system in the context of the cardiac surgeries for childrenThis is a state of use where the size reduction is incredibly important. “

Approach in children with children

This small heart player responds to a particularly sensitive medical need: Newborn with congenital heart defects. Nearly 1 % of children are born with a kind of heart defect, regardless of whether they live in countries with limited or abundant resources.

“The main motivation for our children was. Good news is that. These children only need temporary stimulation after surgery. In nearly seven days, the hearts of most patients will be self. But those seven days are very critical. “

An innovative process with light activation

The system works through an advanced mechanism that combines Severe reduction with genius light activation system. A small heart attack device is planted in the heart and works in conjunction with a An external mobile device that is placed on the patient’s chest.

This outer device Constant monitoring of the heart rate And when he discovers violations, Automatic infrared light pulses. This light, capable of penetration through the skin, sternum and patient muscles, Activating the internal cardiac system Which generates the electrical impulses needed to regulate the rhythm of the heart.

Technology benefits from The natural ability of the human body to perform infrared lightThus creating a bridge that is not expanded between the outer system and the inner heart machine. “Red radiation light Dr. Efimov penetrates “he penetrates well through the body.” If you put a manual lamp on the palm of your hand, you will see the light shining across the other side. It turns out that our bodies are excellent light connectors. “

Delicious technology

Perhaps one of the most revolutionary aspects of this device is that it is designed for Normally melt in the body When you are no longer needed. All ingredients are vital compatible, so they gradually disintegrate in BOID -BIOFLUIDS, which completely eliminates the need for rear surgical extraction.

This distinctive Solve a major problem of current temporary heartbeatThis requires cables that come out of the patient’s chest and must be removed in the end, with the risk of complications such as infections, spaces, tissue damage, bleeding and blood clots that It can be fatal.

Rogers explains: “By reducing the size, We greatly simplify the transplant proceduresReduce the trauma and risks to the patient, and with the dissolved nature of the device, it eliminates any need for secondary extraction surgical procedures. “

The body is fed with the body liquid

To achieve this very low size, researchers The device’s power source was completely invented. The heart attack system works using a galvanic cell, which is a simple but effective type of battery that converts chemical energy for body fluids into electrical energy. The genius design uses two different metal as poles to generate and send electrical impulses to the heart.

This innovation Get rid of the need to include traditional batteries or receiving antennasWhich contributed decisively to the unusual miniaturization of the device.

Diversity and future applications

Despite its small size, The heart attack device provides a large amount of stimulation as a full sizeWhich indicates that in this case, the small does not conflict with efficiency. Severe reduction also allows Distribute many of these devices through different areas of the heartControl independently through different colors of light to achieve more advanced synchronization than traditional heartbeat makers.

This leading technology opens a wide range of possibilities for vital electronic medicine that exceeds the heart field, including applications Nerves and bones help recoverand Treatment of complex wounds Y Prevented Through specific electrical stimuli and control.

The study, published in the prestigious scientific journal “Nature”, shows. The effectiveness of the device in a series of large and small animal modelsAs well as in the hearts of man, who donates the deceased members, which predicts a promising future for its clinical implementation. This is an innovation a The qualitative jump in the treatment of heart diseaseEspecially for smaller and weak patients
