Implantation of repair devices in the heart
First Claim
1. Apparatus, comprising:
- a plurality of helical tissue anchors; and
an intracardiac annuloplasty structure defining a plane of the annuloplasty structure for placement on an annulus of a heart valve, the annuloplasty structure comprising;
a plurality of compressible subunits, anda plurality of anchor mounts alternately disposed with respect to the plurality of compressible subunits, each anchor mount (a) defining at least one opening for passage therethrough of a respective one of the plurality of helical tissue anchors, (b) defining a path for passage therethrough of the respective one of the plurality of helical tissue anchors, 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) providing a structural element in the path for corkscrewing a distal portion of the respective one of the plurality of helical tissue anchors therearound.

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.
