1. A method, comprising:
- obtaining;
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; and
anchoring the annuloplasty structure to a native annulus of a native heart valve with the plurality of helical tissue anchors each passing through a respective path of the plurality of anchor mounts; and
transitioning the annuloplasty structure 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 helical 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 helical anchors and can define a path for passage therethrough of a respective helical 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.

15. A method comprising:
-
obtaining an annuloplasty system 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 comprising struts, and a 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 helical tissue anchor of the plurality of helical tissue anchors; and anchoring the annuloplasty structure to a native annulus of a native heart valve with the plurality of helical tissue anchors each passing along a respective path of the plurality of anchor mounts; and transitioning the annuloplasty structure from a larger configuration to a smaller configuration to reduce a size of the native annulus of the native heart valve. - View Dependent Claims (16)

17. A method for reducing a size dimension of a native annulus of a native heart valve, comprising:
-
obtaining an annuloplasty system 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 rotatable about an axis of rotation of the first ring; and a second ring rotatable about an axis of rotation of the second ring; attaching the annuloplasty structure to the native annulus of the native heart valve; rotating the first ring about the axis of rotation of the first ring to contract at least a portion of the annuloplasty structure while the second ring remains rotationally stationary about the axis of rotation of the second ring; and rotating the second ring about the axis of rotation of the second ring to contract at least a portion of the annuloplasty structure while the first ring remains rotationally stationary about the axis of rotation of the first ring. - View Dependent Claims (18)

19. A method for reshaping a native annulus of a native heart valve, comprising:
-
obtaining an annuloplasty device having a plurality of adjustable segments and a plurality of anchor mounts alternately disposed with respect to the plurality of adjustable segments, wherein the annuloplasty device is adjustable such that it can be used to treat a variety of different sizes of annuli of different patients, and wherein a first segment of the annuloplasty device is adjustable independently of a second segment of the annuloplasty device; anchoring the annuloplasty device to the native annulus of the native heart valve with a plurality of tissue anchors coupled to the plurality of anchor mounts and inserted into tissue of the native annulus; and adjusting the first segment of the annuloplasty device independently of the second segment of the annuloplasty device. - View Dependent Claims (20)
