Artificial vein to boost surgery

British physician Peter Stonebridge first discovered that blood doesn't flow in a linear pattern, but rather in a corkscrew fashion, back in 1991. Now, with help from some colleagues and an NHS grant, he has begun clinical trials of an "rifled" artificial vein with some impressive results.The artificial artery is different from those currently in use because it is "rifled" inside, like a gun barrel, and encourages blood to spiral as it moves along.According to Professor Stonebridge, the simple adjustment from a smooth to a "rifled" vein has produced "remarkable" results in human trials led by researchers at Ghent University Hospital, Belgium.
