Abstract:
1. A device for treating a mitral valve, comprising: a collapsible and expandable prosthetic insert member having first and second longitudinally extending walls, the first and second longitudinally extending walls defining an elongated, crescent-shaped, cross-sectional profile, the insert member having a height sized to extend above and below the mitral valve such that the leaflets of the mitral valve contact the first and second walls of the insert member during ventricular systole for creating a tight seal to prevent regurgitation of blood from the left ventricle to the left atrium, the insert member shaped for permitting the leaflets of the mitral valve to open and close, the insert member formed with a passageway between the first and second walls and a valve member comprising at least one leaflet, the valve member disposed within the passageway for allowing blood to flow through the passageway of the insert member from the left atrium to the left ventricle; an anchoring member coupled to the insert member, the anchoring member comprising an elongated body portion; and a penetration member adapted for engaging tissue along a wall of the left ventricle, the penetration member coupled to a bottom end of the elongated body portion, wherein the anchoring member is dimensioned for positioning the insert member between the leaflets of the mitral valve when the penetration member is engaged with tissue near an apex of the left ventricle, wherein the elongated, crescent-shaped cross-sectional profile is dimensioned to conform to an opening between the native leaflets of the mitral valve.
