摘要： A valve repair system for repairing a native valve of a patient during a non-open-heart procedure includes a delivery device and a valve repair device. The valve repair device include a pair of paddles, first gripping member, a second gripping member, and a spacer. First and second gripping member controls or first and second gripping member control portions are coupled to the first and second gripping members to move the gripping members. The spacer element is configured to close a gap in the native valve of the patient when the valve repair device is attached to the native valve.

摘要： A valve repair devices and systems for repairing a native valve of a patient include a spacer, a pair of paddles, and a pair of moveable clasp arms. The pair of moveable clasp arms are disposed between the pair of paddles and the spacer. The moveable clasp arms are configured to attach to leaflets of a heart valve. The spacer, the pair of paddles, and the moveable clasp arms are configured such that, when attached to the leaflets, the moveable clasp arms are located between the spacer and first portions of the leaflet, while second portions of the leaflet engage the spacer.

摘要： In one representative embodiment, an implantable prosthetic device comprises a spacer body portion configured to be disposed between native leaflets of a heart, and an anchor portion configured to secure the native leaflets against the spacer body portion. The prosthetic device can be movable between multiple configurations. The spacer body can be made from braided, self-expandable metallic thread. A delivery apparatus can have a first shaft and a second shaft, wherein movement of the first shaft relative to the second shaft moves the anchor portion relative to the spacer body.

摘要： An expandable stent for implantation in a right ventricular outflow tract includes a frame having a waist portion that expands to a deployed size having a first diameter, first and second sealing portions extending in opposite directions from the waist portion and expanding radially outward of the waist portion. The first and second sealing portions are sized to seal against first and second portions of the inner surface of the right ventricular outflow tract at the deployed position over a range of sizes of expansion larger than the first diameter. A band is secured to the waist portion of the frame, restricting expansion of the waist portion substantially beyond the first diameter, such that the waist portion is configured to be spaced apart from the inner surface of the right ventricular outflow tract at the deployed position.

摘要： An expandable stent for implantation in a right ventricular outflow tract includes a frame having a plurality of struts that define a repeating pattern of cells. The repeating pattern of cells comprises a column of exactly three generally diamond shaped cells positioned in end-to-end alignment, and a column of exactly two generally diamond shaped cells positioned in end-to-end alignment. The frame has a substantially hourglass shape with a narrow portion in between a proximal end portion and a distal end portion, wherein the proximal end portion and the distal end portion are configured to expand radially outward to contact a right ventricular outflow tract.

摘要： In a method of installing an expandable stent in a right ventricular outflow tract, a frame of the expandable stent is positioned at a deployed position in the right ventricular outflow tract, the frame including a waist portion, and first and second opposed sealing portions extending from the waist portion. The frame is expanded such that the waist portion expands to a first diameter, the first sealing portion expands to a second diameter larger than the first diameter and into contact with a first portion of an inner surface of the right ventricular outflow tract, and the second sealing portion expands to a third diameter larger than the first diameter and into contact with a second portion of the inner surface of the right ventricular outflow tract, wherein the waist portion is spaced apart from the inner surface of the right ventricular outflow tract at the deployed position.

摘要： A valve repair device for repairing a native heart valve of a patient includes a pair of clasps, a pair of paddles, and a coupler. The clasps and paddles are configured to attach to native valve leaflets of the heart valve. The coupler is mechanically connected to the paddles. The coupler is configured to move the paddles between a partially open position and a closed position. The coupler is configured to move freely such that ends of the pair of paddles move away from one another when the native valve leaflets open during a diastolic phase of a cardiac cycle and the ends of the pair of paddles move toward one another when the native valve leaflets close during a ventricular systole of the cardiac cycle.
