Abstract

Valve prostheses for secure, aligned placement to a heart annulus, placed with transcatheter techniques Includes resilient ring, plural leaflet membranes mounted with respect to the ring, plural positioning elements movably mounted with respect to the ring Each positioning element defines proximal, intermediate, distal tissue engaging regions configured and dimensioned to engage separate corresponding areas of anatomical structure, including first, second, third elongate tissue-piercing elements The proximal, distal intermediate tissue-engaging regions configured and dimensioned to engage separate corresponding areas of tissue of anatomical structure to stabilize position of the valve with respect to anatomical structure, simultaneously engaging corresponding areas of tissue, one of the elongate tissue-piercing elements is pointed opposite the direction of blood flow, another is pointed along the direction Includes skirt mounted with respect to the ring, seals periphery of valve against reverse flow of blood.
