Abstract:
The materials for coronary stents preparation can be divided into metal and polymer. Metal stent has excellent processing properties; however, it is limited by the problem such as long-term safety and coronary restenosis. The radical force of polymeric stent is smaller than metal stent, therefore, it is need to make large stent volume with thickness to supporting the vessels, which tents to be a potential danger for blood vessels. Though bioabsorbable alloy stent has the advantage of improving biocompatibility, enhancing vascular remodeling, and reconstructing vascular hemodynamics, it is need to further study the safety. We compared the merits and demerits of different stents materials, explored the development and related questions of drug eluting stents, and analyzed the correlation between processing technology and biocompatibility of stents.
