Scientists are the smallest heartback of the world, the size of a rice grain

Northwest University researchers have created an extraordinarily small heartback Promises to revolutionary heart therapiesEspecially for the most vulnerable patients.

The new device is, Smaller than the grain of the riceSignificant improvement in medical miniatureization. Its abnormally reduced size (1.8 millimeters wide, 3.5 millimeters long and 1 millimeter thick) allows it to introduce the body to the body through a non -syringe free way.

“As far as we know, we have created the world’s smallest heartbreak,” John A. Rogers says, Pioneer in Bio Electronics Northwest and Device Development President. “There is one The main need of a temporary cardiovascular manufacturer in the context of child heart surgeryThis is incredibly important in size miniature, which is a case of application. “

Attitude to child patients

This little heartback responds to a particularly important medical requirement: Newborn people with congenital heart problems. Approximately 1% of children are born with certain types of cardiovascular disorders, regardless of whether they live in countries with limited or resources.

Igor Efimov, the co -chair of the examination of the northwest in the northwest, explains: “Our main motivation is children. Good news is good news These children only need temporary stimulation after surgery. In about seven days, most patients’ hearts are self -relieved. But those seven days are absolutely important. “

Innovative activity with light activity

The system is running through a sophisticated mechanism that combines Intense miniatureization with a unique light activation system. Small heartwarpery is fitted in the heart and acts in a synchronization Outer small device placed on the patient’s chest.

This exterior device Continue monitoring the heartbeat If it is found in abuse, Automatically releases infrared light lentils. This light, skin, sternum and the patient’s muscles are capable of penetrating. Activate the inner heart hug It creates the electrical impulses necessary to control the rhythm of the heart.

Technology uses favorable The natural capacity of the human body to hold infrared lightThus creating a sick bridge between the external device and the inner heart. “Infrared light The body penetrates well, “Dr. Efimov explains.” If you put a incandescent bulb against your palm, you will see the light shining on the other hand. It turns out that our bodies are the best light conductors. “

Biodegradable technology

One of the most revolutionary features of this device is designed Naturally dissolve the body It is no longer necessary. All components are biological compatible, so they gradually disintegrate into the body’s fuels and completely eliminate the need for rear surgery extraction.

This characteristic Solve a significant problem with the current temporary heart hugWith the risk of complications such as infections, displacements, damage to the tissues, bleeding and blood clotting, the patient’s breast emerges from the chest and eventually removed cables. They are dangerous.

Rogers explains: “By reducing the amount, We make the implant procedures hard easily. “

Fluid

To achieve this level of highly reduced, researchers The device has been fully re -found. The heart hip works using a galvanic cell, which is a simple but useful type of battery, which converts the chemical energy of our body’s fluids into electrical energy. The unique design uses two different metals as electrodes, creating and sending electric pulses to the heart.

This is the invention Eliminated the need to add traditional batteries or get antennasIt concluded decisively to the extraordinary miniature of the device.

The future versatile and applications

In spite of its small size, This heartbroken offers stimulant as a full scaleIn this case, the little ones proves that it does not contradict effective performance. Allows for intense miniatureization Distribute many of these devices through different parts of the heartControl them independently by different colors of light to achieve sophisticated synchronization rather than permits traditional heartbreaks.

This pioneer technology opens a wide range of possibilities for bio electronic medicine, including applications for this, beyond the cardiovascular field Help heal the nerves and bonesOvarian Treat complex wounds y Prevent chronic pain By specific and controlled electrical impulses.

This study published in a valuable science magazine ‘Nature’ proves it Device performance in the order of large and small animal modelsAs well as in the human hearts of the dead organ, it foretold the future of the trusted future for its medical activity. This invention is a Quality tab in treatment for heart conditionsEspecially for small and vulnerable patients
