Abstract

In some examples, the disclosure describes an annuloplasty device that comprises a tube-like structure configured to extend around at least part of a circumference of an annulus of a cardiac or vascular valve of a patient, and at least one anchor configured to anchor the tube-like structure to the annulus. The tube-like structure is configured to decrease a distance between valve leaflets that extend from the annulus.

First claim

What is claimed is:

1. A system comprising:
a delivery device configured to access vasculature of a patient; and
an annuloplasty device comprising:
a tube-like structure configured to extend around at least part of a circumference of an annulus of a cardiac or vascular valve; and
a spiral anchor configured to anchor the tube-like structure to the annulus, the spiral anchor being configured to extend spirally through a plurality of holes in the tube-like structure such that the spiral anchor extends longitudinally along at least a length of the tube-like structure,

wherein the delivery device is configured to house the annuloplasty device in a lumen and deliver the annuloplasty device to the annulus of the cardiac or vascular valve and engage the anchors to the annulus, wherein the tube-like structure is configured to decrease a distance between valve leaflets that extend from the annulus, and wherein the delivery device is configured to torque the spiral anchor to advance the spiral anchor in engagement with the tube-like structure.

2. The system of claim 1 , wherein the delivery device comprises a steerable shaft.

3. The system of claim 1 , wherein the delivery device is configured to exert a force on the anchor to engage the anchor with the annulus.

4. The system of claim 1 , wherein the delivery device is configured to manipulate a cinch device to reduce a radius of curvature of the tube-like structure.

5. An annuloplasty device comprising:
a tube-like structure configured to extend around at least part of a circumference of an annulus of a cardiac or vascular valve; and
a spiral anchor configured to extend spirally through a plurality of holes of the tube-like structure to anchor the tube-like structure to the annulus, wherein the spiral anchor extends longitudinally along at least a length of the tube-like structure, wherein the tube-like structure is configured to decrease a distance between valve leaflets that extend from the annulus.

6. The annuloplasty device of claim 5 , wherein the tube-like structure comprises at least one of a stent, a stent having a spiral pattern of crowns and connection nodes, or a cut tube having cuts extending in at least one of circumferential or longitudinal directions of the cut tube.

7. The annuloplasty device of claim 5 , wherein the tube-like structure is a first tube-like structure, further comprising a second tube-like structure coaxially arranged within the first tube-like structure, wherein the second tube-like structure comprises the at least one anchor, wherein the at least one anchor extends radially outward through the first tube-like structure, and wherein the first tube-like structure urges the at least one anchor to engage with tissue.

8. The annuloplasty device of claim 5 , further comprising a cinch wire extending through a bore of the tube-like structure, wherein the cinch wire extends through the bore from a first end of the tube-like device to a second end of the tube-like device.

9. The annuloplasty device of claim 8 , further comprising a first cinch anchor coupled to a first end of the cinch wire and a second cinch anchor coupled to a second end of the cinch wire, opposite the first end of the cinch wire.

10. The annuloplasty device of claim 5 , wherein the tube-like structure is configured to extend from adjacent a first trigone to a second trigone of the cardiac or vascular valve.

11. The annuloplasty device of claim 5 , wherein the tube-like structure is configured to extend around substantially an entire circumference of the annulus.

12. The annuloplasty device of claim 5 , wherein the tube-like structure is configured to extend around a circumference of a mitral annulus of a mitral valve from proximate an anterior valve leaflet to proximate a posterior valve leaflet.
