Heart valve prosthesis with a base, mesh, and dome with a single cavity fixation for preservation, replacement, and / or replacement of native valve function
PROBLEM TO BE SOLVED: To provide an apparatus for extended transplantation in a heart chamber in which fluid is communicated with a native valve having an annulus including an annular plane and a leaflet. SOLUTION: A base 100 including a lower surface at least partially arranged on an annular plane, the lower surface being at least partially arranged on the annular plane, when the base and the device are expanded and implanted. Operates on the atrial dome portion 300, which is under pressure and frictionally engages with the ventricular roof, and the atrial dome portion, which has a flexible expandable mesh and is operably connected to the base frame and apex. A central cylinder valve support 400 that includes an intermediate portion 200 and a lower surface that are operably attached, the central cylinder valve support being operably attached to the base and at least operably attached therein. Includes one prosthesis 402, the lower surface comprising a central cylinder valve support located on or above the annular plane.
