Abstract
An implant is 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 clasps has first and second tissue-engaging portions that are (1) disposed distal to the proximal collar and proximal to the distal collar, and (2) movable, with respect to each other, to clamp one of the leaflets between the tissue-engaging portions of the clasp. The implant is configured such that, when the leaflets are clamped by the clasps, the clasps form the first and second native leaflets into a double orifice, each orifice configured to function as a respective check-valve. Fabric extends distally from the proximal collar on either side of the central longitudinal axis, and is coupled to the clasps. Other embodiments are also described.
