Personalized 3D printed heart implant device new heart of heart disease

Release date: 2014-03-06

Each heart has a different shape, and the current device's epicardial size is not for everyone, not all of the patient's heart geometry, but 3D printing technology can be customized to solve this problem. Recently, researchers in the United States have developed a new type of personalized heart sensor that overcomes many traditional problems and provides new ways to prevent heart attacks.
Since the size of the heart varies from person to person, the current size of medical devices such as pacemakers and defibrillators tends to be the same, which has a certain impact on the treatment of heart disease. In addition, although this device will save the lives of patients, the information obtained is very limited.
Recently, American researchers have developed a new personalized 3D printed heart sensor that overcomes many traditional problems and provides a new way to prevent heart attacks. The researchers used a 3D printer to create a heart model using animal heart images. The flexible electronic components are then mounted above the model. This elastic material is able to peel off the printed model and completely wrap it on the real heart.
The team also integrated a large number of components into the device, such as elastic array sensors, oxidation detectors, strain gauges, electrodes and thermometers, all of which can completely cover the heart. This treatment is more thorough for the patient and provides more personalized monitoring and treatment.
Igor Efimov, a cardiac physiologist and bioengineer at the University of Washington, says implantable defibrillators are a medical device that needs much improvement. It is a device attached to the heart of arrhythmia, with one or two electrodes. The degree determines whether the heart needs to recover from a normal heartbeat by electric shock. However, as long as one or two points of data do not match, the device can make a wrong decision, and sending unnecessary electrodes can cause pain to the patient.
Efimov said: "We are not limited to installing more electronic sensors, but will also install multi-function sensors for the device." For example, sensors that can measure acidic conditions, which can send early signals of coronary artery occlusion. At the same time, light-emitting diodes and light sensors can also provide information on the health of heart tissue by identifying blood with poor oxygen content. Light sensors can even help detect heart attacks.
The researchers used the light image of the rabbit heart to experiment. To make a device available to patients, researchers need to scan the heart of each patient using CT and MRI.
So far, researchers have tested the technique on rabbit hearts that beat in vitro. The next step is to conduct experiments on live animals and finally conduct human clinical trials.
The researchers say the new film can be used in the treatment of diseases in the lower chamber of the heart and can be implanted directly into the heart in the future to treat a variety of diseases, including atrial fibrillation. It is understood that about 3 million to 5 million people in the United States suffer from the disease.
The revolutionary artificial heart film, a revolutionary electronic film, not only allows the rabbit's heart to beat in vitro, but also allows the human heart to beat at a perfect rate, saving many lives.
This thin, retractable circuit film was developed by a team of scientists at the University of Illinois at Urbana-Champaign and the University of Washington at St. Louis. In the next 10-15 years, we will probably see this heart film application in On the human body.
In order to make the film film completely fit the shape of the rabbit's heart, the scientists have come up with a very complete operation process, as follows:
The first step: the rabbit is still alive, and the 3D model of the rabbit heart is scanned by computer-assisted tomography;
Step 2: The scientist prints a 3D model of the heart;
The third step: making a film using a 3D model;
Step 4: Remove the rabbit's heart, cover the membrane, and the heart beats perfectly.
It is worth reminding that this film is not a custom pacing device. John Rorgers, a materials researcher at the University of Illinois, is also one of the leaders of the study. He said that the film acts like a pericardium, but it is artificial.
This artificial pericardium has high-quality artificial electronic devices that can sense heart data and can act on the heart in various ways, which has high clinical value.
Igor Efimov, a biomedical engineering scholar at the University of Washington, says the invention is a huge advancement in the medical world. The circuit on the surface of the film is a number of susceptors that continuously track the movement of the heart and changes in the electrodes to stabilize the heart muscles.
If the sensor detects a sudden emergency such as heart disease or arrhythmia, the sensor will take high-precision treatment on the heart. The membrane can send optimal electrical stimulation signals from different parts to the heart, block arrhythmia, and prevent death from sudden heart disease.
The history of the development of science and technology in 3D printing or 3 madness in 10 years is a history of human understanding of nature and transformation of nature, and an important part of the history of human civilization. When humans fly proudly into space, when robots come out, when high-definition digital color TVs enter daily family life, when the cloned sheep Dolly is born to alarm the whole world, when people are stunned by the magical functions of modern science and technology, are you Learn about 3D printing technology.
A few days ago, the US technology blog ReadWrite published a summary of five crazy things that could be achieved through 3D printing in the next decade, including houses, trees, flesh, human organs and lunar bases. The following is an overview of the article:
Since the first commercial 3D printer was developed by Charles Hull in 1984, 3D printing technology has made great progress in these 30 years. Optimists are convinced that in the next decade, through 3D printing technology, humans can copy houses, trees, flesh, human organs and even lunar bases.
A researcher at the University of Southern California said they have designed a huge 3D printing concept machine that can "build" a 2,500-foot home within 24 hours.
It is said that this concept machine uses concrete as a raw material and can copy pre-designed houses with computer programs. It uses a process called Contour Crafting to ensure that all the necessary water pipes, wire ducts, air conditioning ducts and other facilities in the building are copied in an orderly manner.
For low-cost housing, post-disaster reconstruction, and house models, this 3D printer is of great significance, of course, provided that such a machine really exists, not a conceptual one.
Trees accurately say that such trees are just 3D printed wood.
Two NASA institutes are looking for a way to "grow" trees through 3D bioprinting.
The research team said that cells can produce some non-living matter, such as wood. This 3D printer can print wood through live cells in a specific mode. To achieve this goal, the team has received a $100,000 research and development fund from NASA.
Every meal of the meat and meat, no leather jacket is built on the basis of killing. If the animal's flesh can be obtained through 3D printing, it is very worthwhile to be humanitarian.
Currently, non-Modern Meadow, which is at the forefront of 3D printing bullish by-products, is the only one. The company believes that it is not cost-effective to obtain beef and cowhide through killing. Moreover, there are still many people around the world who are fighting hunger, and the market for synthetic meat is in great demand.
It is understood that this synthetic meat and skin is printed with a raw material called bio-ink. So far, the company has received six-digit research and development funding.
Complex human organs If 3D printing of human organs is finally achieved, organ donation will become history.
Biologists at the University of Louisville's Institute for Cardiovascular Innovation believe that they can create heart organs through 3D printing within 10 years. Currently, the team has been able to create coronary arteries and blood vessels through bioprinting, and they expect to print out the entire heart organ in one go.
Of course, this kind of 3D printing technology doesn't make sense if scientists can't guarantee the survival of 3D printed organs. In 2013, scientists created a liver through bioprinting, but it only survived for five days.
The lunar base of the European Space Agency is considering allowing their astronauts to create a lunar base through 3D printing technology. This is perhaps the most ambitious plan in the field of 3D printing. They are said to plan to use the soil on the moon as a raw material for the printing base.
At present, the European Space Agency's researchers have been able to print 1.5 metric tons of building modules through artificial lunar soil. With these modules, astronauts can build a base.
The American boy's palm is born with a disability. 3D printing is a high school student Mason. This is a high school student Mason. He finds the robot program on the Internet and inputs it into the local library's 3D printer. It takes only 8 Hours.
BEIJING, Feb. 19, according to foreign media reports, a boy with a natural palm disability in the United States recently regained a "manipulator" for 3D printing technology, and only one high school student who built this hand for him .
American 9-year-old boy Matthew Shield lives in Kansas. He was born with a thumb in his right hand due to natural illness. This has seriously affected his interaction with people. He is always not confident.
Shields' mother noticed his problem and turned to a friend Mason. Mason is a high school student. He found a program about the robot on the Internet and imported it into the local library's 3D printer. This made a hand for Shield.
The process of making a hand only takes 8 hours. Now, Shields is very happy. He can grab things with his right hand, write, and can change his wrist and do a lot of things.
Even better, the cost of this new hand is only a fraction of the traditional manipulator. Traditional robots cost tens of thousands of dollars, and Shields' family is hard to pay.

Vacuum Sweet Corn Kernels

For the most common waxy and sweet corn on the market, waxy corn has a higher nutrient content than regular corn, containing 70-75% starch (and almost all straight-chain starch), more than 10% protein, 4-5% fat and 2% multivitamins, with more grains, VA, VB1 and VB2 in protein than rice, with the highest fat and VB2 content. Yellow maize also contains carotenoids, such as rice and wheat. The molecular weight of waxy maize starch is more than 10 times smaller than that of ordinary maize, and the starch makes glutinous rice sticky and soft, softer than ordinary hard maize. It is more than 20% more digestible to eat than regular maize and it is suitable for people with less than perfect teeth. At the same time, it is not suitable for diabetics because of the very high content of straight-chain starch (a polysaccharide).

Waxy maize is also known as sticky maize. The grain has coarse, waxy endosperm, similar to shiny, glassy (clear) grains such as hard and dent maize. Its chemical and physical characteristics are controlled by a recessive gene, which is located on chromosome 9. 100% of the starch in the endosperm is straight-chain starch.
