摘要：
A tissue anchor (200, 258, 300) includes a shaft (122), a tissue-coupling element (128), and a flexible elongate tension member (202). The tissue-coupling element (128) includes a wire (150), which is shaped as an open loop (154) having more than one turn when the tissue anchor (200, 258, 300) is unconstrained. The tension member (202) includes a distal portion (204) that is fixed to a site (206) on the open loop (154), a proximal portion (208), which has a longitudinal segment (209) that runs alongside at least a portion (210) of the shaft (122), and a crossing portion (212), which (i) is disposed between the distal and the proximal portions (204, 208) along the tension member (202), and (ii) crosses at least a portion of the open loop (154) when the tissue anchor (200, 258, 300) is unconstrained. The tissue anchor (200, 258, 300) is configured to allow relative axial motion between the at least a portion (210) of the shaft (122) and the longitudinal segment (209) of the proximal portion (208) of the tension member (202) when the tissue anchor (200, 258, 300) is unconstrained.
