Heart valve sealing devices and delivery devices therefor
A valve repair device includes a pair of anchors and at least one leak inhibitor. The device can also include a spacer or coaptation element. The pair of anchors can be coupled to the spacer or coaptation element. The pair of anchors are movable between an open position and a closed position and are configured to attach the valve repair device to the native valve of the patient. The at least one leak inhibitor extends between the pair of anchors and is configured to inhibit retrograde blood flow through the device, for example, between one or more openings between leaflet portions that are in the anchors.
1 . A valve repair device for repairing a native valve of a heart of a patient, the valve repair device comprising:
an anchor portion comprising a first anchor and a second anchor, wherein the first and second anchors are configured to be moved from an open position to a closed position to secure the implantable device to leaflets of a native valve;
a barrier element attached to the first anchor and the second anchor such that the barrier element extends between the first anchor and the second anchor to inhibit blood regurgitation through one or more openings between leaflets of the native valve during systole;
wherein the barrier element is a component of a leak control extension that comprises one or more deflecting paddles;
wherein the one or more deflecting paddles are configured to flex toward a ventricle of the heart during diastole; and
wherein the one or more deflecting paddles are configured to flex toward an atrium of the heart during systole.
2 . The valve repair device according to claim 1 , wherein the barrier element comprises one or more pieces of a cloth material.
3 . The valve repair device according to claim 1 , wherein the barrier element comprises one or more pieces of a biocompatible material.
4 . The valve repair device according to claim 1 , wherein the barrier element extends from the first anchor to the second anchor to create a barrier that extends between the first anchor and the second anchor.
5 . The valve repair device according to claim 1 , wherein each of the first and second anchors comprise a paddle frame, and wherein the barrier element is attached to the paddle frame of both the first and second anchors.
6 . The valve repair device according to claim 1 , further comprising a spacer disposed between the first anchor and the second anchor.
7 . A valve repair device for repairing a native valve of a patient, the valve repair device comprising:
an anchor portion comprising a first anchor and a second anchor, wherein the first and second anchors are configured to be moved from an open position to a closed position to secure the implantable device to leaflets of a native valve;
a leak control extension that comprises one or more deflecting paddles;
wherein the one or more deflecting paddles are positioned in a ventricle of the native valve when the implantable device is secured to the leaflets of the native valve;
wherein the one or more deflecting paddles are configured to flex toward an atrium of the heart during systole; and
wherein the one or more deflecting paddles are configured to flex toward a ventricle of the heart during diastole.
8 . The valve repair device of claim 7 wherein the leak control extensions are configured to prevent blood from flowing through openings between the device and the leaflets of the native valve.
9 . The valve repair device according to claim 7 , wherein each of the first and second anchors comprise a paddle frame.
10 . The valve repair device of claim 9 further comprising a cap attached to the pair of paddle frames, wherein distal movement of the cap opens the first and second anchors, and wherein the one or more deflecting paddles are attached to the cap.
11 . The valve repair device of claim 10 wherein the deflecting paddles are configured to pivot relative to the cap when the native valve is in diastole such that blood moves around the deflecting paddles from the atrium to the ventricle.
12 . The valve repair device of claim 7 wherein the deflecting paddles are configured to flex when the native valve is in diastole such that blood moves around the deflecting paddles from the atrium to the ventricle.
13 . The valve repair device according to claim 7 , further comprising a spacer disposed between the first anchor and the second anchor.
