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.

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: 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: An implantable prosthetic device can include a spacer member, a plurality of anchors, and a plurality of clasps. The spacer member can be configured to be disposed between native leaflets of a heart. The anchors can be coupled to the spacer member and configured to secure the native leaflets against the spacer member. The clasps can be coupled to a respective anchor and configured to secure the native leaflets to the anchors. The clasps can be independently movable between an open configuration and a closed configuration.

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 includes a pair of barbed clasps. The barbed clasps are in a closed condition while the mitral valve repair device is in the extended condition in the delivery sheath.

Abstract: A pair of paddles are moved laterally away from one another in an exemplary method of repairing a native valve of a patient during a non-open-heart procedure. After the paddles are moved laterally away from one another, first and second gripping members are moved from an open position to a closed position to grasp valve leaflets. The paddles are then moved laterally toward one another. A cam can be used to move the paddles away from one another.

Abstract: An exemplary valve repair device is released from tissue of a valve of a patient by applying tension to a movable arm of a clasp in a retraction direction. A fixed arm of the clasp is attached to an inner paddle portion of a paddle of the valve repair device. The inner paddle portion is connected to an outer paddle portion of the paddle of the valve repair device. Pulling the moveable arm of the clasp flexes the inner paddle portion to allow the moveable arm to move in the retraction direction and thereby release the clasp from the valve tissue.

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.
