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 clip and a clip deployment and delivery system. The clip may be engaged with a clip spreader such that simple relative movement, such as sliding movement, between the clip and clip spreader causes the clip and clip spreader to disengage from each other. A clip spreader actuator may be coupled to one arm of the clip spreader, extend distally around a distal end of the clip spreader, proximally along the other clip spreader arm, and to a proximal end at which the actuator may be controlled to open or close the clip spreader. The clips may be leaflet clips having teeth on one arm thereof and bumps on another arm thereof. The arms of the leaflet clip may be biased into a closed configuration by a flex zone which has an expanded portion extending laterally away from only one of the clip arms.

Abstract: A tissue anchor and an anchor delivery and deployment system. The tissue anchor is shiftable between a delivery configuration when housed in anchor garage of the anchor delivery and deployment system, and a deployment configuration when deployed outside the anchor garage. The anchor has a plurality of talons which may be formed from a laser cut tube. The talons may taper, such as widthwise.
