STENT WITH RETRACTABLE ANCHORS

A stent includes a tubular support structure extending from a distal end to a proximal end, the tubular support structure including an inner surface and an outer surface. A retractable anchor system is disposed relative to the tubular support structure and includes a frame member and a plurality of retractable anchors secured to the frame member. The plurality of retractable anchors are biased toa deployed configuration in which the plurality of retractable anchors extend radially outward from the outer surface of the tubular support structure but are radially inwardly compressible into a delivery configuration. 种支架，所述支架包括管状支撑结构，所述管状支撑结构从远侧端部延伸至近侧端部，所述管状支撑结构包括内表面和外表面。可回缩锚定件系统相对于所述管状支撑结构设置并且包括框架构件和固定至所述框架构件的多个可回缩锚定件。所述多个可回缩锚定件偏置至其中所述多个可回缩锚定件从所述管状支撑结构的所述外表面径向地向外延伸的展开配置，但可径向地向内压缩至递送配置。
