应用自体细胞和生物可降解支架材料，已经制造出组织工程肺动脉瓣膜和肺动脉，但在主动脉系统中的研究少有报道。

With autologous cells and biodegradable copolymer scaffold, some laboratory had been created autologous pulmonary valve leaflets and pulmonary artery, but seldom successful reports in aortic systemic.

我们认为，未来通过研发新型支架设计、生物可降解支架及其他改善治疗安全性的方法，可以进一步提高我们的水平。

We think we will reach an even higher level in the future with further innovative stent designs, bioabsorbable stents, and other ways to improve the safety of that treatment process.
