Abstract

Devices for treating mitral valve regurgitation, including a distal expandable anchor, a proximal expandable anchor, and a fixed length connecting member extending from the proximal expandable anchor to the distal expandable anchor, where at least one of the proximal and distal anchors includes first and second arm segments that extend from one end of the device toward the connecting member and the other anchor when in a collapsed delivery configuration, and where the at least one of the proximal and distal anchors that comprises the first and second arm segments has an expanded configuration in which the first and second arm segments extend radially outwardly such that the first and second arm segments extend away from one another toward the connector, and meet one another at a location axially spaced from the end of the device.

Claims

1. A device for treating mitral valve regurgitation, comprising:

a distal expandable anchor, a proximal expandable anchor, a fixed length connecting member extending from the proximal expandable anchor to the distal expandable anchor, a distal end, a proximal end, and an axis that extends between the distal and proximal ends and along the connecting member,

wherein at least one of the proximal and distal anchors comprises first and second arm segments and has an expanded configuration, wherein in the expanded configuration the first and second arm segments extend from one of the distal and proximal ends of the device away from one another, radially outward, and axially toward the connector, and then meet one another at an anchor apex that is axially spaced from the one of the distal and proximal ends of the device, the anchor apex being disposed in an anchor portion that is spaced radially furthest away from the axis.

2. The device of claim 1 wherein the distal expandable anchor comprises the first and second arms segments and the one of the distal and proximal ends is the distal end, such that in the expanded configuration the first and second arm segments extend away from one another at the distal end of the device, proximally toward the connector, and then meet one another at the anchor apex that is proximal to the distal end.

3. The device of claim 1 wherein the proximal expandable anchor comprises the first and second arms segments and the one of the distal and proximal ends is the proximal end, such that in the expanded configuration the first and second arm segments extend away from one another at the proximal end of the device, distally toward the connector, and then meet one another at the anchor apex that is distal to the proximal end.

4. A device for treating mitral valve regurgitation, comprising:

a distal expandable anchor, a proximal expandable anchor, a fixed length connecting member extending from the proximal expandable anchor to the distal expandable anchor, a distal end, a proximal end, and an axis that extends between the distal and proximal ends and along the connecting member,

wherein at least one of the proximal and distal anchors comprises first and second arm segments and has an expanded configuration, wherein in the expanded configuration the first and second arm segments diverge relative to one another, then extend radially outward and axially, and then meet one another at an anchor apex that is axially spaced from where the first and second segments diverge relative to one another, the anchor apex being disposed in an anchor portion that is spaced radially furthest away from the axis.

5. The device of claim 4, wherein the distal expandable anchor comprises the first and second arm segments, and in the expanded configuration the first and second arm segments, after diverging relative to one another, extend radially outward and proximally toward the connecting member, and then meet one another at the anchor apex that is proximal to a distal end of the device.

6. The device of claim 4, wherein the proximal expandable anchor comprises the first and second arm segments, and in the expanded configuration the first and second arm segments, after diverging relative to one another, extend radially outward and distally toward the connecting member, and then meet one another at the anchor apex that is distal to a proximal end of the device.
