PERCUTANEOUS TISSUE ANCHOR TECHNIQUES

摘要

A first element (91) includes a first arm (92) and a second arm coupled thereto and having a concavity (103) facing the first arm and defining a space (96). In an open state, a tissue anchor portion (46) moves into the space through a gap between distal portions (94) of the first and second arms. In the closed state, the anchor portion is not movable through the gap. A second element (82) is movable with respect to the first element, such that, while the portion (46) of the anchor (40) is within the space, and the first element is in the closed state, in a first position of the second element, the portion of the anchor is movable within the space, and in a second position of the second element, the second element applies torque to the anchor by rotating the second element. Other embodiments are also described.

1. Apparatus for use with a tissue anchor, the apparatus comprising:
a first element comprising:
a first arm; anda second arm, shaped to define a concavity, and movably coupled to the first arm such that:
the concavity faces the first arm, and defines at least part of a space,in an open state of the first element, a gap is defined between a distal portion of the first arm and a distal portion of the second arm through which a portion of the tissue anchor is movable into the space, andin a closed state of the first element, the portion of the tissue anchor is not movable through the gap; and a second element, movable with respect to the first element such that, while (1) the portion of the tissue anchor is disposed within the space, and (2) the first element is in the closed state thereof:
in a first position of the second element with respect to the first element, the portion of the tissue anchor is movable within the space, andin a second position of the second element with respect to the first element, the second element is positioned to apply torque to the tissue anchor by rotation of the second element.
