Are the findings of optical coherence tomography sufficient for the evaluation of the safety and efficacy of the next generation of drug eluting stents
The cr8 stent is a next generation drug eluting stent (DES) with a polymer free abluminal reservoir drug release system. It uses an organic fatty acid permeation enhancer and a carbon surface to increase biocompatibility. The fatty acid enhancer may have beneficial effect in improving drug delivery in diabetic patient where neointimal hyperplasia is particularly problematic. These types of design features are exciting new developments and may provide novel strategies for improving the safety and efficacy of the next generation of coronary stents.
