An implant is configured to be coupled to first and second native leaflets of a native heart valve of a patient. The implant includes a proximal collar, a distal collar, and first and second clasps. Each of the first and second clasps has first and second tissue-engaging portions that are (1) disposed distal to the proximal collar and proximal to the distal collar, (2) movable, with respect to each other, to clamp one of the leaflets between the first and second tissue-engaging portions of the clasp, and (3) movable, when clamped to the leaflet, toward and away from a central longitudinal axis of the implant. The implant includes fabric (i) extending distally from the proximal collar on either side of the central longitudinal axis, and (ii) coupled to the first and second clasps. Other embodiments are also described.
