Heart valve anchoring device
First Claim
1. An anchoring device for anchoring a prosthetic heart valve support supporting a prosthetic heart valve inside a heart, said anchoring device comprising an extraventricular part designed to be positioned inside an atrium or an artery and a ventricular part designed to be positioned inside a ventricle, wherein said ventricular part comprises a double wall composed of an outer wall and an inner wall spaced apart at a level where the prosthetic heart valve is intended to be inserted, andwherein the anchoring device comprises a predefined V-shaped groove formed between the extraventricular part and the ventricular part;
- the outer wall and the inner wall are connected at a folded end;
the extraventricular part comprises at least one extraventricular flange extending from the outer wall or the inner wall;
an extraventricular side of the V-shaped groove comprises the at least one extraventricular flange and a ventricular side of the V-shaped groove comprises the outer wall of the ventricular part;
the ventricular part comprises a cylindrical inner wall;
the outer wall is characterized by a decreasing diameter and has a smaller diameter directed in a direction of the extraventricular part and a lamer diameter connected to the cylindrical inner wall at the folded end; and
the extraventricular part comprises at least one cylindrical portion extending from the at least one extraventricular flange in a direction opposite to the ventricular part.
