可重新定位的腔内支撑结构及其应用
摘要：
一种腔内支撑结构(10)，包括由回转接头(15)互相连接而形成一系列相连结的剪式机构的支杆件(11)。该结构可被远程致动以通过在一运动范围内调节剪式接头而压缩或扩展其形状。特别地，该支撑结构可在身体内腔中被重新定位或从内腔取回。可采用该支撑结构将人工瓣膜(100)引入和支撑在身体内腔中。
摘要（英）：

An endo luminal support structure includes strut members interconnected by swivel joints to form a series of linked scissor mechanisms. The structure can be remotely actuated to compress or expand its shape by adjusting the scissor joints within a range of motion. In particular, the support structure can be repositioned within the body lumen or retrieved from the lumen. The support structure can be employed to introduce and support a prosthetic valve within a body lumen.
