摘要： A replacement valve prosthesis includes a support structure and a valve body having three flexible leaflets. The support structure preferably includes an internal valve frame and an external sealing frame. The valve frame supports the flexible leaflets. The sealing frame is adapted to conform to the shape of the native heart valve annulus. The sealing frame may be coupled to an inlet end of the valve frame, an outlet end of the valve frame, or both. A plurality of anchors is coupled to the outlet end of the valve frame. The anchors extend radially outwardly for placement behind native leaflets. The prosthesis preferably includes a skirt disposed along an exterior of the external sealing frame. The prosthesis is collapsible for delivery into the heart via a delivery catheter. The prosthesis is configured to self-expand for deployment in the heart when released from the delivery catheter.

摘要： An implantable prosthetic device includes a plurality of anchor members, a plurality of clasps, and a cover. The plurality of clasps are configured to capture the leaflets to secure the leaflets to the anchor members. The cover is disposed over the plurality of anchor members. The cover can also be disposed over the clasps and a spacer member. A portion of the cover can be covered by a coupler. One or more extensions of a coupling collar can extend through the cover.

摘要： 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.

摘要： An implantable prosthetic device includes a spacer member configured to be disposed between leaflets of a native heart valve that is located between a first chamber and a second chamber of the heart. The prosthetic device further includes a plurality of anchor members coupled to the spacer member and configured to capture the leaflets between respective anchor members and the spacer member such that the prosthetic device is retained between the leaflets. The spacer member is configured to provide a flow path through the prosthetic device between the first chamber and the second chamber when the leaflets are captured between the anchor members and the spacer member such that blood can flow regurgitatively from the second chamber to the first chamber through the spacer member.

摘要： 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.

摘要： 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.
