All stents fail. So what happens next?

andrew nicolaidesBackground

If you are familiar with the nature of endovascular procedures, you’ll know that eventually, all stents fail. At this point, many vascular surgeons choose to redo the stent, but what if there was a long-term solution?

Andrew N. Nicolaides, Professor Emeritus of the Imperial College of London is among  a group of researchers who have done the most studies with grafted arteriopaths using ArtAssist®…the Arterial Assist Device®, to improve blood flow to the lower extremities. This group discovered that using the ArtAssist® device on patients who had already undergone a successful endovascular procedure enhanced arterial circulation.

New Hypothesis

After having confirmed this discovery, Professor Nicolaides and his team in London are thinking about the next step:  after the arterial stent inevitably fails, the patient now has an alternative to getting another stent. If a patient uses the ArtAssist® device while his stent is still in place, Professor Nicolaides hypothesizes, by the time the stent fails, his artery will be capable of accommodating the same beneficial amount of blood as before, and he will not need to go in for another procedure.

Interview

Now that you have a bit of a background, I’ll let Professor Nicolaides explain it in his own words.

ArtAssist Arterial Assist Device

UPDATE

July 13, 2012:  A veteran researcher of the ArtAssist® device has recently agreed to test Prof. Nicolaides’ hypothesis. Stay tuned for more information!
