Abstract: 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 configured to extend radially outwardly as the spacer body extends away from the distal end toward the proximal end. 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.

Abstract: In one example, 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. A size of the spacer body is configured to be adjusted after the spacer body is placed between the native valve leaflets and the pair of anchors are placed against the ventricular surfaces of the native heart valve leaflets. 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.

Abstract: A valve repair device for repairing a native valve of a patient includes a spacer element, a pair of paddles, and a pair of gripping members. The pair of paddles is coupled to the spacer element. The pair of gripping members is disposed between the pair of paddles. The paddles and the gripping members are configured to attach to leaflets of a heart valve. The spacer element extends past side edges of the gripping members, extends past side edges of the paddles, or extends past the side edges of both the gripping members and the paddles.

Abstract: A valve repair device includes a first paddle, a second paddle, a spacer, a first gripping member, and a second gripping member. The first paddle and the second paddle are configured to move between a closed position and an open position. The spacer is disposed between the first paddle and the second paddle. The first gripping member is disposed between the first paddle and the spacer. The second gripping member is disposed between the second paddle and the spacer. The first paddle and the first gripping member are configured to capture a first native valve leaflet. The second paddle and the second gripping member are configured to capture a second native valve leaflet.

Abstract: A delivery apparatus includes a steerable guide sheath. The steerable guide sheath has a steerable portion, a pull ring located in the distal portion, and a pull wire coupled at one end to the pull ring and coupled at the opposite end to a control handle. The pull wire extends longitudinally through a pull-wire conduit. The steerable guide sheath further includes a compression-resistance portion made of metal and located in the distal portion.

Abstract: Disclosed herein are steerable catheter assemblies and methods of steering catheters that utilize driver and follower mechanisms to accomplish independent control of catheter flex magnitude and catheter flex direction. Some embodiments include a catheter with a first pull wire and a second pull wire that flex the catheter, a control handle coupled to the catheter, a first follower connected to the first pull wire, a second follower connected to the second pull wire, and a driver disposed in the control handle and coupled to the first and second followers. The rotation of the driver coupled to the control handle moves the first and second followers in opposite directions, and axial movement of the driver moves the first and second followers in the same direction.
