Abstract
The disclosure describes an annuloplasty device that includes a wire configured to extend around at least part of an annulus of a cardiac or vascular valve, such as at least partially around a circumference of the annulus, and a plurality of anchors. The anchors of the plurality of anchors are configured to engage the wire and anchor the wire to the annulus. The wire is configured to urge at least some anchors of the plurality of anchors toward each other in a radially inward direction to decrease a distance between valve leaflets that extend from the annulus.
Claims9
An annuloplasty device comprising:
- a wire having a plurality of substantially straight segments connected by pivot points comprising coils formed by the wire, the wire configured to extend around at least part of an annulus of a cardiac or vascular valve;
- a plurality of anchors configured to:
- engage the wire, and
- anchor the wire to the annulus;
- and
- a plurality of length control elements, wherein a respective length control element is configured to selectively engage with a respective inner diameter of each respective coil, wherein the coils are configured to assume a reduced diameter and urge adjacent anchors of the plurality of anchors toward each other when the respective length control element is disengaged from the respective coil,
- wherein the wire is configured to urge at least some anchors of the plurality of anchors toward each other in a radially inward direction to decrease a distance between valve leaflets that extend from the annulus.
