Götz M. Richter, M.D., Ph.D., Professor of Radiology, Department of Diagnostic Radiology and Vice Chairman at the University of Heidelberg, Heidelberg, Germany discussed problems with current stents and presented some of the new developments in the technology.

Past problems polymer deficiencies, impurity, poor device-to-blood interface (i.e. endothelial cells don't "like" the polymers). Dr. Richter discussed the Nanoscale Polyzene-F stent, which is showing results of being much better in background and molecular structure, with high purity, and a hydrophobic surface that translates into ideal cell "friendliness."

The coating, or lining, promotes restenosis when examined at four weeks. The Atlanta FIM Catania Stent Study, presented at the Transcatheter Cardiovascular Therapeutics (TCT) conference in 2008, showed a 100% technical success.

The results included zero percent thrombosis in patients discontinuing anti-platelet therapy after only 30 days. At twelve months, there was also zero percent death, myocardial infarction, stroke, or coronary artery bypass graft.

Dr. Richter stated that breaking studies in computational fluid dynamics showed a great early potential for high tech engineered modifications of the stent design, comparing it to the new wing technology in airplanes, relating to the significance of wall sheer (WSS).

Stated Dr. Richter, "Areas of low WSS contain a greater amount of neoinimal hyperplasia than areas subjected to higher WSS."
