Abstract
Apparatus is provided, including a plurality of helical tissue anchors and an intracardiac annuloplasty structure defining a plane for placement on a heart valve annulus. The annuloplasty structure includes a plurality of compressible subunits, and a plurality of anchor mounts alternately disposed with respect to the plurality of compressible subunits. Each anchor mount (a) defines at least one opening for passage therethrough of a respective helical tissue anchor, (b) defines a path for passage therethrough of the helical tissue anchor, the path being aligned along an axis that is at a non-zero angle with respect to the plane of the annuloplasty structure, and (c) provides a structural element in the path for corkscrewing a distal portion of the helical tissue anchor therearound. Other embodiments are also described.
