Abstract: Valve repair devices and systems configured to detect proper valve leaflet insertion. The device/system can have a pair of paddles and a clasp attached to each of the paddles. The clasps can have a fixed arm attached to the paddle, a movable arm connected to the fixed arm that is movable between an open position and a closed position. The device can have an indicator that can move between not engaged by a leaflet and engaged by a leaflet conditions to indicate capture of a leaflet of the native valve. The indicator can be compressible. The indicator can be flattenable. The indicator can include one or more marker.

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 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: Valve repair devices and systems configured to detect proper valve leaflet insertion. The device/system can have a pair of paddles and a clasp attached to each of the paddles. The clasps may have a fixed arm attached to the paddle, a movable arm connected to the fixed arm that is movable between an open position and a closed position, and an indicator arm connected to at least one of the fixed arm and the movable arm. The indicator arm can move between a first position when not engaged with a leaflet and a second, engaged position when engaged with the leaflet. Movement of the indicator arm from the first position to the second, engaged position indicates capture of a leaflet of the native valve by the pair of paddles.

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. In some implementations, the implantable device or implant, or one or more portions thereof, can be configured to expand and/or contract. For example, the implantable device or implant can narrow during delivery and expand on implantation on the native heart valve.
