From the abluminal biodegradable polymer stent to the polymer free stent. Clinical evidence

The implementation of methods of the coronary angioplasty was one of the most important achievement in the field of treatment of coronary artery disease. Abluminal biodegradable polymer stents (BDS) and polymer free stent are the newest and the most promising research concerning coronary stent technology. In this article we discuss the perceived need for BDS-polymer free stents, the current clinical evidence, limits and future perspectives.
