US researchers develop anastomosis tool using medical magnets

Using a pair of medical magnets, a new anastomosis tool has been developed by US researchers at the University of California, San Francisco.

Even during complicated Polycarbonate Market the proof-of-concept study's findings, which were published in the Journal of the American College of Surgeons, demonstrated that the device was safe and simple to use.

Using staples or sutures, an anastomosis is a surgical connection between tubular anatomic structures like blood vessels, the urinary tract, or the bowel.

A Magnamosis device with two rare-earth magnets enclosed in a medical-grade polycarbonate shell is used in the new magnetic compression anastomosis method.

Because of their distinct shapes and polarities, the magnetic implants are attracted to one another and provide a comfortable fit.

The anastomosis is made by applying a force of magnetic attraction, so there are no complicated sutures or expensive staples required.

"None of the patients reported complications related to the anastomosis or the magnet, such as leaking, bleeding, or stricture,"

The study included three patients with bladder and bowel complications and two with end-stage renal disease. After using the Magnamosis device, surgeons were able to make an anastomosis in 25-35 minutes.

None of the patients reported anastomosis or magnet-related complications like leaking, bleeding, or stricture during follow-up visits.

Michael Harrison, emeritus professor of surgery at the University of California, San Francisco, stated: The Magnamosis device is still very much in its infancy.

"It can be tested under the conditions of a clinical trial because it has an investigative device exemption from the US Food and Drug Administration."

While Magnamosis was developed at the University, the medical device company Magnamosis is working on marketing it.
