Abstract

Apparatus, systems, and methods are provided for percutaneous transcatheter delivery and fixation of annuloplasty rings to heart valves. An annuloplasty ring includes an outer tube, an inner body member, and an anchor deployment system. The outer tube includes a plurality of windows and has an axis along its length. The internal body member includes a plurality of anchors formed perpendicular to the axis. The anchor deployment system selectively rotates the internal body member with respect to the axis of the outer tube. The rotation deploys the plurality of anchors through the plurality of windows.

Claims

1. An annuloplasty ring for transcatheter heart valve repair, the annuloplasty ring comprising:

an outer hollow member configured to change from an elongate insertion geometry to an annular operable geometry, the outer hollow member comprising a plurality of windows;

a first internal anchor member located at least partially within the outer hollow member, the first internal anchor member comprising a plurality of first anchors configured to attach the annuloplasty ring to tissue of a heart valve annulus, the first internal anchor member configured to move the plurality of first anchors with respect to corresponding windows of the plurality of windows in the outer hollow member to selectively deploy the plurality of first anchors through the corresponding windows; and

a second internal anchor member located at least partially within the outer hollow member, the second internal anchor member comprising a plurality of second anchors configured to attach the annuloplasty ring to the tissue of the heart valve annulus, the second internal anchor member configured to move the plurality of second anchors with respect to corresponding windows of the plurality of windows in the outer hollow member to selectively deploy the plurality of second anchors through the corresponding windows;

wherein the first internal anchor member and the second internal anchor member are independent, separate structures and are independently movable with respect to each other.

2. The annuloplasty ring of claim 1, wherein the plurality of first anchors and the plurality of second anchors are configured to deploy at substantially the same time.

3. The annuloplasty ring of claim 1, wherein the plurality of first anchors and the plurality of second anchors are configured to selectively deploy at different times.

4. The annuloplasty ring of claim 1, wherein the plurality of first anchors curve in a first direction in a deployed configuration, and the plurality of second anchors curve in a second direction in the deployed configuration, the second direction being different than the first direction.

5. The annuloplasty ring of claim 4, wherein the plurality of first anchors are each adjacent to a corresponding one of the plurality of second anchors in the deployed configuration.

6. The annuloplasty ring of claim 5, wherein adjacent anchors deploy through a same window of the plurality of windows.

7. The annuloplasty ring of claim 5, wherein adjacent anchors deploy through separate, adjacent windows of the plurality of windows.

8. The annuloplasty ring of claim 1, wherein at least one of the plurality of first anchors and one of the plurality of second anchors include a shape in a deployed configuration selected from a group comprising curved, wavy, straight, and curled.

9. The annuloplasty ring of claim 1, further comprising:

a third internal anchor member located at least partially within the outer hollow member, the third internal anchor member comprising a plurality of third anchors configured to attach the annuloplasty ring to the tissue of the heart valve annulus, the third internal anchor member configured to move the plurality of third anchors with respect to corresponding windows of the plurality of windows in the outer hollow member to selectively deploy the plurality of third anchors through the corresponding windows, wherein the plurality of third anchors are selectively deployable independent of the first plurality of anchors and the second plurality of anchors.
