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 apparatus for delivering a prosthetic heart valve includes a steerable guide catheter, a balloon catheter, and a flex indicator. The guide catheter has a handle and a guide tube extending from the handle. The guide tube has a distal end portion comprising a steerable section. The guide catheter further includes an adjustment mechanism on the handle and a pull wire connecting the adjustment mechanism to the steerable section for changing flexion of the steerable section. The balloon catheter includes a shaft extending coaxially through the guide tube. The shaft includes a proximal end portion and a distal end portion. The balloon catheter further includes a balloon mounted on the distal end portion of the shaft. The flex indicator moves relative to the handle upon adjustment of the adjustment mechanism. The handle includes visual indicia adjacent the flex indicator to provide visual indication of the flexion of the steerable section.

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.

摘要： 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.
