New Technique for Keeping Blood Vessels Open

29.05.2007
Scientists at the University of Ulster are working on a new method of coating stents – the medical devices used to keep veins and arteries open – to prevent them blocking up.

The team involving Professors Jim McLaughlin, John Anderson and Paul Maguire are based at the Northern Ireland Bio-Engineering Centre (NIBEC) on the University’s Jordanstown campus.

Details of their work were unveiled today in Japan at the opening of a four day conference. Professor McLaughlin presented the keynote address to the New Diamond and Nano-Carbons conference in Osaka.

He said the UU scientists are working to further develop and even commercialise a 3-D plasma coating technique, which has already been shown to be highly biocompatible and promising with regards to its mechanical properties.

Many of the team’s findings have already been published in scientific journals and have attracted keen interest worldwide.

Stents are tubular scaffold structures that are inserted into blood vessels which have become narrowed and led to reduced blood flow to the body’s organs.

Professor McLaughlin said: “One of the setbacks of vascular stents is the potential development of a thick-smooth muscle tissue inside the stent cavity, the so-called neointima. Development of a neointima is variable but can be so severe as to re-occlude the vessel leading to the blood vessel narrowing again (restenosis), which often results in re-intervention.

”Considerable improvements have been made, including the use of more bio-compatible materials, anti-inflammatory drug-eluting stents, re-sorbable stents, and others.

”Fortunately, even if stents are eventually covered by neointima, the minimally invasive nature of their deployment makes reintervention possible and usually straightforward.”

”However long-term restenosis is being noted in polymer coated stents due to polymer-to-stent bare-metal adhesion failures and the build up of a thrombosis. Our group based at NIBEC are now seeking to further develop and even commercialise a 3-D plasma-coating technique, which has already shown to be highly biocompatible and promising with regards to it’s mechanical properties,” Professor McLaughlin added.

Im Focus: Hybrid optics bring color imaging using ultrathin metalenses into focus

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.

But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...

Im Focus: Stem cell divisions in the adult brain seen for the first time

Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.

The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...

Im Focus: Autonomous 3D scanner supports individual manufacturing processes

Let’s say the armrest is broken in your vintage car. As things stand, you would need a lot of luck and persistence to find the right spare part. But in the world of Industrie 4.0 and production with batch sizes of one, you can simply scan the armrest and print it out. This is made possible by the first ever 3D scanner capable of working autonomously and in real time. The autonomous scanning system will be on display at the Hannover Messe Preview on February 6 and at the Hannover Messe proper from April 23 to 27, 2018 (Hall 6, Booth A30).

Part of the charm of vintage cars is that they stopped making them long ago, so it is special when you do see one out on the roads. If something breaks or...
