摘要： Disclosed prosthetic valves can comprise a sewing ring configured to secure the valve to an implantation site. Some disclosed valves comprise a resiliently collapsible frame having a neutral configuration and a collapsed deployment configuration. Some disclosed frames can self-expand to the neutral configuration when released from the collapsed deployment configuration. Collapsing a disclosed valve can provide convenient access to the sewing ring, such as for securing the valve to the implantation site, as well as for the insertion of the valve through relatively small surgical incisions.

摘要翻译： 公开的假体瓣膜可以包括构造成将瓣膜固定到植入部位的缝合环。 一些公开的阀包括具有中性构型和折叠展开构型的弹性可折叠框架。 当从折叠部署配置释放时，一些公开的框架可以自扩展到中立配置。 折叠所公开的阀可以方便地进入缝合环，例如用于将瓣膜固定到植入部位，以及通过相对较小的手术切口插入瓣膜。 用于部署阀的递送系统和方法的示例表现出减少的患者创伤。
