Abstract: An exemplary valve repair device for repairing a valve of a patient has a paddle, and a clasp. The clasp has a fixed arm attached to the paddle and a moveable arm. The moveable arm includes barbs that are spaced apart from a connection between the moveable arm and the fixed arm. The moveable arm is movable between open and closed positions relative to the fixed arm. The moveable arm has a weakened portion between the barbs and the connection between the moveable arm and the fixed arm. Applying tension to the movable arm in a retraction direction stretches the moveable arm and moves the barbs in the retraction direction.

Abstract: An exemplary valve repair device for repairing a native valve of a patient includes a coaption element, a collar, a pair of paddles, a cap, and a shaft. The coaption element has a first end portion and a second end portion. The collar is connected to the first end portion of the coaption element. The pair of paddles each include an inner paddle portion and an outer paddle portion that are movable between an open position, a closed position, and a bailout position. The cap is connected to the pair of paddles. The shaft extends through the collar and the coaption element and is connected to the cap. Movement of the cap by the shaft causes the inner paddle portions and the outer paddle portions of the pair of paddles to move between the open position, the closed position, and the bailout position. When the paddles are in the bailout position, a bailout angle between each inner paddle portion and the shaft is greater than or equal to 120 degrees.

Abstract: An exemplary implantable prosthetic device has a coaption element and a pair of paddles. The coaption element has a first end portion and a second end portion. The pair of paddles is connected to the second end portion of the coaption element. The coaption element narrows as the copation element extends from the first end portion to the second end portion. The paddles are movable between an open position and a closed position. The paddles are configured to attach to the native valve of the patient.

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 expand and contract. For example, the implantable device or implant can narrow during delivery and expand on implantation on the native heart valve.

Abstract: A coronary artery check valve includes a stent configured to attach to an inner wall of a coronary artery of a living subject, and a tapered helical coil coupled to the stent and configured to regulate blood flow in the coronary artery. The coronary artery check valve is configured to prevent retrograde flow of the coronary blood supply during diastole by closing during systole of the heart when the tapered helical coil compresses longitudinally, and opening when the tapered helical coil expands longitudinally to permit blood flow into the coronary artery when a coronary pressure of the living subject drops below diastolic blood pressure.

Abstract: A valve repair device for repairing a native valve of a patient. The valve repair device includes a paddle, a gripping member, and an indicator. The paddle and/or the gripping member are movable to form an opening or capture region between the gripping member and the paddle. The indicator is configured to indicate whether a leaflet of the native valve is inserted into the opening or capture region between the paddle and the gripping member to at least a minimum insertion depth.

Abstract: An implantable device or implant includes an anchor portion comprising one or more anchors. The anchors are configured to attach to one or more leaflets of a native heart valve. The anchors are configured to move between an open position and a closed position. The device or implant includes an indication feature that is movable between an allowable tension position and an exceeded tension position. When the anchors are attached to the leaflets of the native heart valve, the indication feature indicates to a user when an amount of force applied to the anchor portion by the leaflets of the native heart valve exceeds a pre-set or predetermined amount of force.
