Magnetic Device that Holds Wounds Together May Replace Stitches and Staples in the Future

Magnamosis, a magnetic doughnut-shaped device, has been shown to hold wounds together and may soon replace stitches and staples in common surgical procedures. According to researchers who tested the device in a trial in California, the new device allows for safer procedures and much faster healing.

The revolutionary device consists of two ring magnets measuring 23 mm in diameter and have concave or convex surfaces so they can fit snugly against each other. The device works by holding the two ends of blood vessels or other structures with a strong magnetic bond that researchers believe leads to more secure anastomosis and faster healing.


Anastomosis refers to reconnection of two structures and is usually done using staples or stitches. It is commonly used in bowel surgery and other weight-loss procedures.

With the use of Magnamosis, the process takes less than a week. The device automatically loosens its magnetic hold and is naturally removed from the body.

The device has been proven reliable and effective in a series of animal studies. So far, it is now being used in a clinical trial with 10 patients for the first time. The patients, who will be undergoing intestine surgery, will have it done using the Magnamosis device. For two years, they will be monitored to check how good the connection is and to detect side-effects like leaks and fever.
Compared to standard techniques, Magnamosis is cheaper and is done using less invasive surgery.

Royal College of Surgeons spokesman Dr. Shafi Ahmed said there is a need to explore different ways of stitching the bowel together.

“This is potentially a very exciting and novel idea, which could involve not having to use stitches, making an operation quicker,” he said.

However, he reminded that it will take quite a long time before the device is used in clinical practice.

What is Magnetic Therapy?

An alternative medical practice utilizing static magnets, magnetic therapy is believed to alleviate pain and other health concerns. This therapy is commonly integrated in rings, bracelets, shoe inserts, clothing and even therapeutic magnetic mattresses.

Although this practice lacks scientific evidence to back up its claims, global sale of therapeutic magnets is approximately at least $1 billion annually.
