1. A four quadrant frame for an artificial valve prosthesis, each quadrant comprising:
- a U-shaped member having a bight and a first end point and a second end point opposite the first end point, anda supporting arm transversing the U-shaped member,the quadrants being formed into a tubular structure defining a longitudinal axis, the tubular structure being formed by the U-shaped member of each quadrant being connected to the U-shaped member of an adjacent quadrant in mirror symmetry at a first connection and a second connection;
the first connection being between the first end point of each U-shaped member and the second end point of the adjacent U-shaped member, and the second connection being between the bight of each U-shaped member and the bight of the adjacent U-shaped member.

Abstract
The disclosure relates to implantable prosthetic valves comprising support frames. The support frames may include a plurality of symmetrically arrayed interconnected U-shaped member structures. Preferred support frames are tubular structures enclosing a longitudinal axis and including a plurality of U-shaped member structures facing a distal or a proximal end of the support frame. Each U-shaped member structure may be connected to a single longitudinally adjacent U-shaped member facing in an opposite longitudinal direction, as well as two laterally adjacent U-shaped members.

17. An artificial valve prosthesis comprising:
-
four quadrant frame, each quadrant comprising a U-shaped member having a bight with a first radius and a first end point and a second end point opposite the first end point; and a supporting arm transversing the U-shaped member; the quadrants being formed into a tubular structure defining a lumen with longitudinal axis, the tubular structure being formed by the U-shaped member of each quadrant being connected to the U-shaped member of an adjacent quadrant in mirror symmetry at a first connection and a second connection;
the first connection being between the first end point of the U-shaped member of each quadrant and the second end point of the U-shaped member of the adjacent quadrant and forming a bend having a second radius that is less than the first radius of the bight; and
the second connection being between the bight of the U-shaped member of each quadrant and the bight of the U-shaped member of the adjacent quadrant; anda valve leaflet comprising a first edge attached to the frame and a second edge attached to the frame, the valve leaflet being positioned within the lumen, where the valve leaflet prevents or permits fluid flow through the lumen. - View Dependent Claims (18)
