CYPHER~(TM)支架的杰出表现可以归诸于三个要素的最佳组合。从药物本身而言,需要考虑平衡药物疗效和安全因素两方面。支架平台,需要结合支架传统的机械性要素和提供药物释放的适宜平台。此外,聚合物释放系统,必须能够提供一种介质以达到最佳药物释放的目的,这种介质必须能够承受安置支架时的张力,但不引发炎症反应。 The outstanding performance of CYPHER ~ (TM) stents can be attributed to the best combination of the three elements. In terms of the drug itself, there are two aspects that need to be considered to balance the efficacy and safety of the drug. The scaffold platform needs to incorporate the traditional mechanical features of the scaffold and a suitable platform to provide drug release. In addition, the polymer delivery system must be able to provide a medium for optimal drug release that must withstand the tension at the time of placement of the stent but not induce an inflammatory response.
