摘要常规覆膜支架的原位开窗术是临床上治疗突发性复杂主动脉瘤的主要手段之一。然而,常规覆膜支架在原位开窗后,由于球囊扩张后织物覆膜的撕裂、稳定性差等原因,极易发生内漏,造成覆膜支架体内失效。本研究拟设计并制备一种具有梯度化结构的原位开窗用织物覆膜,包括基础区、加固区和开窗区,旨在加强开窗区边缘的抗撕裂能力。结果表明,具有梯度化结构原位开窗用织物覆膜的壁厚小于0.14 mm,水渗透性低于300 mL/min/cm²,平纹-方平-斜纹试样的周向拉伸断裂强度高于商用样Anaconda(11.10 N/mm),顶破强度基本低于商用样Anaconda,基本满足覆膜支架织物覆膜的结构与力学性能要求。加固区的抗撕裂强力优于开窗区,可有效提高织物覆膜加固区的抗撕裂性能。单股纬纱型平纹-方平-斜纹试样的力学性能较好,且织物各向异性较小,更适合作为原位开窗用织物覆膜,但其远期耐久性能仍需进一步研究。
