Abstract: Anchor delivery systems and methods for repairing a valve inside a body, such as an atrioventricular valve, may include an anchor delivery device including a sheath for at least partially retaining an anchor in a collapsed form. The anchor delivery device may be configured to deliver the anchor to the atrioventricular valve. The anchor and an adjacent anchor may be connectable to each other in an expanded form, to link a series of anchors implanted at least partially around the atrioventricular valve. In some embodiments, the anchors may be connectable by a connecting member, such as a pledget, or a material disposable on a bulb of the anchor. In other embodiments, a bulb of the anchor and a bulb of the adjacent anchor may be configured to be directly interlocked.

Abstract: The present disclosure relates generally to the field of medical devices for delivering artificial chordae tendineae in a patient. In an embodiment, an anchor is movable between a delivery configuration and a deployed configuration, the anchor being in the delivery configuration when disposed within a delivery catheter, the anchor being in the deployed configuration when the anchor is moved beyond a distal end of the delivery catheter. When the anchor is in the delivery configuration it has a first outer dimension and when the anchor is in the deployed configuration it has a second outer dimension, the first outer dimension being smaller than the second outer dimension. The anchor is engageable with a papillary muscle or a heart wall when the anchor is in the deployed configuration and is also coupleable to an artificial chordae tendineae to anchor the artificial chordae tendineae to the papillary muscle or heart wall.

Abstract: The present disclosure relates generally to the field of medical devices for treating heart disease. In particular, the present disclosure relates to medical devices, systems, and methods for delivering artificial chordae tendineae in a patient. A system for delivering a chordae tendineae into a heart may include a delivery catheter. A clamp catheter may be configured to translate through the delivery catheter. A spreader may be disposed on the clamp catheter. A first clamp may be at least partially contained in the spreader in a closed configuration and may be attached to the chordae tendineae. An anchor catheter may be configured to translate through the delivery catheter and may have an anchor attached to the chordae tendineae. A sheath may be extended over the anchor catheter and anchor and may be configured to restrain an arm of the anchor.

Abstract: Devices, systems, and method for adjusting and setting tension of an artificial chordae tendineae. The artificial chordae tendineae is coupleable between a leaflet clip and a tissue anchor. A locking assembly, through which the artificial chordae tendineae extends, is shiftable between a tension-adjusting configuration, in which the artificial chordae tendineae is movable to adjust tension on the leaflet, and a tension-setting or locked configuration, in which the artificial chordae tendineae is inhibited or prevented or locked against moving with respect to the locking assembly to set or fix tension on the leaflet.

Abstract: A valve fixation device may comprise a unitary elongate member that is biased towards a closed configuration wherein at least a pair of tissue engaging surfaces of the elongate member are held adjacent to each other by a bias force. The bias force is at least equal to a valve leaflet grasping force, enabling the fixation device to grasp and retain leaflets as part of cardiac treatment. A delivery tool including a spreader may independently translate the tissue engaging surfaces to enable cardiac leaflets to be captured and retained by and/or between the tissue engaging surfaces. The valve fixation device may include at least two arms, each of which may be independently controlled to grasp and capture opposing leaflets of a valve, such as the anterior and posterior leaflets of a mitral valve, to reduce the size of the valve opening and improve cardiac performance.
