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: An implantable device or implant is configured to be positioned within a native heart valve to allow the native heart valve to form a more effective seal. The implantable device or implant can include a pair of paddles frame a coaptation element. The coaptation element defines a first area when viewed from above. The paddle frames define when viewed from above. A ratio of the second area to the first area is greater than or equal to 2 to 1.

Abstract: An implantable prosthetic device has a coaption element and at least one anchor. The coaption 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 coaption element can have a structure that is impervious to blood. The coaption element can be connected to leaflets of the native valve by the anchor.

Abstract: In one embodiment, an expandable positioning device for improving the coaptation of heart valve leaflets is provided. The expandable positioning device can include one or more expandable members. A first expandable member extends below a leaflet in order to reposition the leaflet to improve coaptation with another leaflet. A second expandable member extends above a leaflet in order to secure the expandable delivery device at the implantation site. The expandable positioning device can include a neck that is inserted through the leaflet on which the device is implanted. The expandable positioning device can include a coupling member to releasably couple the device to a delivery device. One or more sealing members can be included in the expandable positioning device to maintain a desired level of expansion of the one or more expandable members.

Abstract: A mitral valve repair system includes a delivery sheath, a mitral valve repair device, and an actuator. The mitral valve repair device is disposed in the delivery sheath in an extended condition. The mitral valve repair device is movable out of the delivery sheath while in the extended condition. The actuator is coupled to the mitral valve repair device, such that retracting the actuator reduces a length of the mitral valve repair device from the extended condition.
