Abstract: An implantable heart valve device has a main body including a first end portion and a second end portion. The main body is configured to be implanted around a native leaflet of a heart valve such that the first end portion is on an atrial side of the leaflet and the second end portion is on a ventricular side of the leaflet, and such that the main body can coapt with an opposing native leaflet during operation of the heart valve. One of the first or second end portions comprises a coupling assembly, and the other of the first or second end portions comprises a coupling member configured to extend through the native leaflet when the heart valve device is implanted in a heart valve. The coupling assembly is configured to releasably engage the coupling member to permit adjustment of the relative positions of the first and second end portions.

Abstract: An exemplary valve repair device for repairing a native valve of a patient has a pair of paddles, a pair of gripping members, and at least one latch member. The paddles are movable between an open position and a closed position. The paddles and/or the gripping members are configured to attach to the native valve of the patient. When the paddles are in the closed position, the latch members latch the paddles in the closed position.

Abstract: Embodiments of an apparatus, and a method for crimping expandable stents or prosthetic valves having a radially expandable and compressible annular body and one or more protruding anchors extending from the body using the apparatus, where the apparatus comprise a housing, a plurality of circumferentially arranged nesting jaws, and an actuator configured to move the jaws radially inwardly to reduce the size of the crimping aperture, thereby radially compressing the annular body of the prosthetic valve or stent. In particular embodiments, a selected set of the jaws, each having a front side and a recessed portion in its front side adjacent to its inner end. The recessed portions of the selected jaws collectively are sized and shaped to receive the one or more anchors of the prosthetic valve when the annular body is positioned within the crimping aperture.

Abstract: A delivery handle for implanting a prosthetic device at one of a mitral, aortic, tricuspid, and pulmonary valve region of a human heart includes a housing and an actuation control mechanism. The actuation control mechanism includes a knob and an actuation tube. The knob is rotatably coupled to the housing. The actuation tube is coupled to the knob such that rotation of the knob in a first direction moves the actuation tube distally relative to the housing and rotation of the knob in a second direction moves the actuation tube proximally relative to the housing.

Abstract: 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.

Abstract: Implementations of the tissue illumination systems, devices, and methods disclosed herein take advantage of the translucent nature of tissue to reveal properties by light transmission, for example, tissue type, tissue transition locations, underlying structures, and the like, that are not easily distinguished by reflected light. Illuminating a back-side of a translucent tissue permits a user to distinguish between different types of tissue, tissue transition locations, and/or structures that are difficult or impossible to discern under overhead or front-side illumination. Implementations include a light source that is positionable behind a tissue or disposable within a body cavity or duct, for example, within a heart ventricle.
