1. An apparatus, comprising:
- a plurality of helical tissue anchors; and
an 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 defining a path for passage of a respective one of the plurality of helical tissue anchors;
wherein the annuloplasty structure can be transitioned from a first configuration having a first diameter to a second configuration having a second diameter different from the first diameter.

Abstract
Apparatuses and devices usable for annuloplasty are provided. These can include a plurality of tissue anchors and an annuloplasty structure for placement on a heart valve annulus. The annuloplasty structure can include a plurality of compressible or adjustable subunits, and a plurality of anchor mounts alternately disposed with respect to the plurality of compressible/adjustable subunits. The anchor mounts are coupleable to the tissue anchors and can define a path for passage therethrough of a respective tissue anchor. The apparatuses and devices can be independently adjustable and can be adjustable for treating various sizes of patient annuli. Other embodiments are also described.

19. An annuloplasty system for reducing a size dimension of an annulus of a heart valve, comprising:
-
an annuloplasty structure comprising a plurality of adjustable subunits and a plurality of anchor mounts alternately disposed with respect to the plurality of adjustable subunits; a first ring; and a second ring, wherein the first ring is rotatable about its axis of rotation to contract the annuloplasty structure while the second ring remains rotationally stationary about its axis of rotation, and the second ring is rotatable about its of rotation to contract the annuloplasty structure while the first ring remains rotationally stationary about its axis of rotation.

20. An annuloplasty system for reshaping an annulus of a native heart valve, comprising:
-
an annuloplasty structure comprising a plurality of adjustable segments and a plurality of anchor mounts connected to the plurality of adjustable segments; a plurality of tissue anchors; wherein each anchor mount of the plurality of anchor mounts is coupleable to a respective tissue anchor of the plurality of tissue anchors, such that the plurality of tissue anchors can be implanted in the annulus of the native heart valve to secure the annuloplasty structure to the annulus of the native heart valve at the plurality of anchor mounts; and wherein the annuloplasty structure is adjustable such that it can be used to treat a variety of different sizes of annuli of different patients, and a first segment of the annuloplasty structure is adjustable independently of a second segment of the annuloplasty structure.
