Patent attributes
A prosthetic valve comprises a first frame, defining an arrangement of cells; a second frame, a first protrusion, and a second protrusion. In an expanded state of the valve, the first frame is generally cylindrical and has an expanded width, and the valve defines a lumen having a first end and a second end. In a compressed state of the valve, the first and second frames are both generally cylindrical, and the first frame has a compressed width that is smaller than the expanded width. In the expanded state, the valve provides directional fluid flow through the lumen. The valve defines first and second coupling points, and an axis therebetween, the axis lying on a transverse cross-section of the first frame. The first and second coupling points couple the second frame to the first frame by protruding into respective first and second slots defined by the first frame.
