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, wherein the prosthetic device is movable between a compressed configuration, in which the spacer body portion is radially compressed and is axially spaced relative to the anchor portion, and an expanded configuration, in which the spacer body portion expands radially outwardly relative to the compressed configuration and overlaps at least a portion of the anchor portion.

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： 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.
