生物可降解血管内支架研究进展

Progress in Researches of Biodegradable Intravascular Stents

生物可降解血管内支架具有良好的生物相容性,当所支撑的狭窄段血管恢复畅通、内膜修复完成后即可降解消失,克服了支架自身的血栓原性及异物性,避免了支架引起的远期并发症。本文综述了生物可降解血管内支架的研究进展,重点介绍了生物可降解聚合物血管内支架的选材、制备、设计及临床应用进展。

Biodegradable intravascular stents （BIS） become degraded after the short-term need for a stent and thus avoid the potential long-term complications of metal stents. In this paper, the research progress of BIS was reviewed; the materials, fabrication, design, experimental and clinical tests of biodegradable polymeric intravascular stents （BPIS） are introduced.
