摘要： In a particular embodiment, the present disclosure provides a delivery apparatus for delivering a medical device. The delivery apparatus includes an elongated component with an engagement portion and a disengagement portion. Rotating the elongated component in a first rotational direction moves the travelling component along the engagement portion in a first axial direction. When the travelling component is located within the disengagement portion, continued rotation of the elongated component in the first rotational direction does not cause further movement of the travelling component in the first axial direction. A biasing member is located proximate the disengagement portion and urges the travelling component to reengage the engagement potion. The delivery apparatus can reduce or prevent damage to the delivery apparatus, or a patient with whom the delivery apparatus is used, by reducing or eliminating torque transfer from the travelling component to an end of the elongated component.

摘要： In a particular embodiment, the present disclosure provides a prosthetic valve delivery assembly that includes a storage tube. A prosthetic valve having a frame is at least partially disposed within the storage tube. A nose cone is located distally to the valve. A removable tab is disposed between the distal end of the frame and the nose cone. The tab assists in maintaining the position of the nose cone relative to the distal end of the frame.

摘要： Disclosed herein are catheter control handles that include various cam-based mechanisms for controlling the circumferential angle and radial magnitude of flexion of an attached catheter. Control handles can comprise a housing defining a longitudinal axis extending in distal and proximal directions, a cam member that is movable axially relative to the housing and also movable rotationally about the longitudinal axis relative to the housing, at least one follower engaged with the cam member such that the at least one follower moves relative to the handle in response to the movement of the cam member, and pull wires that are coupled to the at least one follower and that extend distally out of the handle and into a steerable catheter. The at least one follower can comprise plural axial sliders, a gimbal mechanism, a ball and socket mechanism, or other mechanisms.

摘要： An exemplary implantable prosthetic device has a coaption element and at least one anchor. The coaption element is configured to be positioned within the native heart valve orifice to help fill a space where the native valve is regurgitant and form a more effective seal. The coaption element can have a structure that is impervious to blood and that allows the native leaflets to close around the coaption element during ventricular systole to block blood from flowing from the left or right ventricle back into the left or right atrium, respectively. The coaption element can be connected to leaflets of the native valve by the anchor.

摘要： A delivery apparatus includes a steerable shaft having a proximal portion, a distal portion, and a pull-wire conduit that extends through the proximal and distal portions. A pull wire extends through the conduit and has a distal portion that is fixed to the shaft. An adjustment mechanism is connected to the proximal end portion of the pull wire and configured to increase and decrease tension in the pull wire to adjust the curvature of the shaft. The distal portion of the shaft has a steerable portion including one or more layers. A compression-resistance portion is incorporated into a layer of the steerable portion, and extends angularly along a portion of a cross-section of the layer. The layer of the steerable portion into which the compression-resistance portion is incorporated has a first hardness, and the compression-resistance portion has a second hardness that is greater than the first hardness.
