Systems and methods for heart valve leaflet repair

A system for use with a valve of a heart of a subject, the valve having a first leaflet and an opposing leaflet, the heart having a chamber upstream of the valve, and the system comprising:

• an implant, comprising:
• an interface,
• an anchor receiver at the interface, and
• a flexible wing, coupled to the interface, and having a contact face and an opposing face opposite the contact face;
• an anchor, comprising a tissue-engaging element;
• a catheter, transluminally advanceable to the chamber, and configured to house the implant;
• and
• a delivery tool, comprising:
• a shaft, housing the anchor, engaged with the interface, and configured via the engagement with the interface to, while the anchor remains within the shaft:
• deploy the implant out of the catheter such that, within the chamber, the wing extends away from the interface, and
• position the implant in a position in which the interface is at a site in the chamber, the wing extends over the first leaflet toward the opposing leaflet, and the contact face faces the first leaflet, and
• a driver, engaged with the anchor within the shaft, and configured to secure the implant in the position by, while the implant remains in the position, anchoring the anchor receiver to the site by driving the tissue-engaging element distally through the anchor receiver and into tissue at the site.
