摘要： An apparatus for repairing a heart valve can comprises a leaflet-plicating mechanism configured to plicate a leaflet of a heart valve and a helical needle comprising a plurality of coils. The needle can be configured to implant a suture to extend helically through plicated tissue of the heart valve. The leaflet-plicating mechanism can comprise first and second leaflet-capture arms, which can be configured to move toward and away from each other between an open position and closed position. The leaflet-capture arms can be configured to plicate the leaflet as the leaflet-capture arms are moved from the open position to the closed position.

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

摘要： An exemplary valve repair system for repairing a native valve of a patient during a non-open-heart procedure has a delivery device and a valve repair device. The valve repair device is configured to be delivered through a lumen of the delivery device and to attach to a native valve of a patient. The valve repair device has first and second paddles and first and second gripping members. The first and second paddles are movable between an open position and a closed position. The first gripping member is attached to the first paddle and the second gripping member is attached to the second paddle. The gripping members are configured to attach to the native valve of the patient. A gripper control mechanism is configured to separately move the first and second gripping members.

摘要： In an exemplary method of implanting a valve repair device on a mitral valve of a patient, first and second clasps of the valve repair device are closed to grasp the leaflets of the mitral valve. First and second paddles of the valve repair device are closed to bring the leaflets of the mitral valve into contact with a coaption element.

摘要： Apparatus for repairing a leaflet of a heart valve can include a leaflet-plicating tool that can include leaflet-capture arms and a helical needle. The needle can be operatively coupled to the leaflet-capture arms. The leaflet-capture arms can include an arm-shaft, each configured to house a leaflet-engaging member. The leaflet-capture arms can be configured to use the leaflet-engaging members, extended over the leaflet from the annulus toward a free edge of the leaflet, to form a plication in the leaflet of the heart valve between the leaflet-capture arms. The leaflet-plicating tool can be configured to secure the plication by using the helical needle to stitch a suture helically along the plication. Other embodiments are also described.

摘要： 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.

摘要： 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.
