Abstract: An exemplary valve repair device for repairing a native valve of a patient includes: a coaption element formed from a strip of material; a pair of extension members; a pair of paddles formed from the strip of material and connected to the coaption element; and a cap attached to the paddles. The paddles are movable between an open position and a closed position, are disposed over the extension member, and are configured to attach to the native valve of the patient. Movement of the cap toward the coaption element causes the pair of paddles to move to the closed position, and movement of the cap away from the coaption element causes the pair of paddles to move to the open position. The cap has a retention body for receiving attachment portions of the extension members, a retaining nut, and a retaining bolt for securing the retaining nut.

Abstract: An device for treating a native valve includes a sealing element and an anchoring element. The sealing element is made from a braided mesh material. The sealing element is dimensioned to be deployed in an annulus of a native valve of a heart at a position between native valve leaflets to contact the native valve leaflets during ventricular systole to create a seal to prevent regurgitation of blood from the left ventricle to the left atrium. The sealing element is configured to both be radially expanded and radially reduced while at the position between the native valve leaflets. The anchoring element is adapted for deployment in the heart, the anchoring element coupled to the sealing element and configured to support the sealing element at the desired position between native valve leaflets.

Abstract: In a method of treating an atrioventricular valve, a sealing element is deployed in a native atrioventricular valve of a heart at a position between native atrioventricular valve leaflets to contact the native atrioventricular valve leaflets. The sealing element is controlled by user input to both radially expand and radially reduce the sealing element while at the position between the native atrioventricular valve leaflets. At least one of the native atrioventricular leaflets is secured between an inner anchor member and an outer anchor member to support the sealing element at a desired position between the native atrioventricular valve leaflets.

Abstract: An implantable prosthetic device has a coaptation element and at least one anchor. The coaptation element is configured to be positioned within the native heart valve orifice to help fill a space where the native valve is regurgitant and form a more effective seal. The coaptation element can have a structure that is impervious to blood. The coaptation element can be connected to leaflets of the native valve by the anchor.

Abstract: An exemplary valve repair device for repairing a native valve of a patient includes: a strip of material; a coaption element formed from the strip of material; a pair of paddles formed from the strip of material and connected to the coaption element; a cap attached to the paddles; and a pair of extension members connected to the cap and the paddles via attachment portions. The paddles are movable between an open position and a closed position and are configured to attach to the native valve of the patient. Movement of the cap toward the coaption element causes the pair of paddles to move to the closed position, and movement of the cap away from the coaption element causes the pair of paddles to move to the open position. The extension members extend to end portions attached to the strip material. The end portions extend beyond the strip of material.

The paddles are movable between an open position and a closed position and are configured to attach to the native valve of the patient. Movement of the cap toward the coaption element causes the pair of paddles to move to the closed position, and movement of the cap away from the coaption element causes the pair of paddles to move to the open position. In the closed position the extension members are biased in a closing direction.
