Sutureless Method for Joining Blood Vessels Invented

Much testing remains....not ready for prime time just yet.

Reconnecting severed blood vessels is mostly done the same way today -- with sutures -- as it was 100 years ago, when the French surgeon Alexis Carrel won a Nobel Prize for advancing the technique. Now, a team of researchers at the Stanford University School of Medicine has developed a sutureless method that appears to be a faster, safer and easier alternative.

Good stuff huh....I also noticed these sections of the article.

Sutures are troublesome in other ways, too. They can lead to complications, such as intimal hyperplasia, in which cells respond to the trauma of the needle and thread by proliferating on the inside wall of the blood vessel, causing it to narrow at that point. This increases the risk of a blood clot getting stuck and obstructing blood flow. In addition, sutures may trigger an immune response, leading to inflamed tissue that also increases the risk of a blockage.

The authors say further testing on large animals is needed before human trials can begin, but they note that all of the components used in the technique are already approved by the FDA. "This technology has the potential to progress rapidly from the 'bench to bedside,'" they write.

He continued: "Coming up with this solution was the result of the classic Stanford model of bringing together researchers from a variety of disciplines."
