Various stent structures are provided with improved axial and torsional flexibility. One type of stent structure includes multiple segmented stent structures connected to each other by biodegradable interconnectors. A delivery system adapted to delivery the multiple segmented stents is also described. Another type of stent structure includes biodegradable connectors that are incorporated into a framework of non-biodegradable interconnecting members that form the support structure of the stent. The biodegradable connectors in both stent structures degrade or are absorbed after the stent is deployed. Stabilizing elements may be provided to the stent structures to supplement the stiffness of the stent with stability during loading and deployment.
各种支架结构具有更好的轴向和扭转柔韧性。其中一种支架结构包括通过
生物可降解互连器相互连接的多个分段支架结构。此外,还介绍了一种适用于输送多个分段支架的输送系统。另一种支架结构包括可
生物降解连接器,这些连接器与构成支架支撑结构的不可
生物降解互连构件框架结合在一起。这两种支架结构中的可
生物降解连接器在支架展开后都会降解或被吸收。支架结构中可加入稳定元件,以补充支架的刚度,并在加载和展开过程中保持稳定。
