The first surgical procedure performed was a small piece of paper that electrocuted the injured tissue. initiate vascular remodeling, which the group tested rats. Rogers teamed up with cardiologists, including Arora, who saw an opportunity to give up the artificial respiratory system used to treat cardiac music. Rogers likens this dissolving tool to an internal medicine, an “electrical product” in which all substances are dissolved.
At first glance, the device is about half an inch long, inches long it looks like a smooth piece of plastic. But, basically, it’s a moving layer with carefully selected objects. The electrical connectors are a mixture of tungsten and magnesium. Wireless power feeds in the connections even the tiny antennae that are made of the same material. The power comes from a connection near the field, or an NFC-assisted antenna, which can be placed on a hospital bed or a patch of clothing. (Sorry, NFC for charging your phone is not really good enough to break any hearts.)
Having a stable electrical connection is essential for any cardiovascular system, as any blood transfusion depends on Cardiovascular cells shoot faster. But the weapon also needs to be strong. When a wet heart is saturated with dehydration, its wrinkled form has problems. The challenge of making something that is sustainable and volatility has been “like a question open on the field for a while,” says Rogers. “Bioelectronics is great, but how can you maintain strong connections over time?”
The team confuses the problem with adhesives, which don’t just stick to the heart of the machine – they just stick medicine. Hydrogel forms a bond that binds to the muscle. Loose water cables on hydrogel and heart woven together with the product. Nitrogen atoms in one fuse contain carbon atoms in the other, and vice versa, to form strong bonds, similar to proteins. Roger says: “It uses a very simple, powerful electrical connection.”
Each part can be melted as soon as it is wet, and it is important that the device is not damaged as soon as you install it. As a result, a computer manufacturer lives inside a molten shell that acts as a time connector – the hardware has two weeks to run when the shell melts. Everything else begins to deteriorate later, but by that time, the patient would no longer need a pacemaker. With a temporary tool, the team can make verison with a larger capsule.
The team tested the device on animals with small hearts (rats and mice), middle hearts (rabbits), and others with human-like hearts (dogs). In all cases, their weapons could drive the animal’s collision. (They also tested the muscles that are farther away from the donors in humans and did the same.)
The Rogers and Arora team also tested how the gamers tie themselves to rats. He pointed out that the equipment did not move for one week, melted down after three weeks, and stopped working for four weeks. By 12 weeks, it was all over.
“Completing the operation, and completely destroying the whole thing without having anything dangerous or dangerous – it’s very difficult,” he says. Ellen Roche, A medical specialist at MIT who manufactures cardiovascular instruments, who is not involved in the operation. “Independently, one is possible,” Roche continues. “But I think doing it all together, I think, is a great thing.”
“It’s wonderful to see simple things; we already know about their toxicity problem, “says Chris Bettinger, engineer Carnegie Mellon.” I think that simple things are often not appreciated. “
But a destructive tool like a pacemaker will need to be tested more to ensure that people are safe. Another problem may be a heart condition, which may be more severe among heart patients than among lab animals. Raman, a cardiologist outside Arora, says some of the people who may need such a device have stomach ulcers caused by heart disease and obstruction, which can make it difficult to connect. “But based on the design, one might think it should work,” Raman said.
