Abstract

L'invention concerne une valve mitrale prothétique comprenant un ensemble d'ancrage, un cadre d'entretoise et une pluralité de valvules de remplacement fixées au cadre d'entretoise annulaire. L'ensemble d'ancrage comprend une ancre ventriculaire, une ancre atriale et une partie centrale située entre ces dernières. L'ancre ventriculaire et l'ancre atriale sont conçues de façon à s'évaser radialement vers l'extérieur par rapport à la partie centrale. Le cadre d'entretoise annulaire est disposé radialement à l'intérieur de l'ensemble d'ancrage et est fixé à l'ensemble d'ancrage. La partie centrale est conçue de façon à s'aligner avec un orifice de valve native et l'ancre ventriculaire et l'ancre atriale sont conçues pour comprimer un tissu cardiaque natif entre elles.
