Prosthetic heart valve having non-cylindrical frame

An implantable prosthetic device, comprising:

• a frame having first and second opposing axial ends, the frame comprising:
• a first set of a plurality of struts extending in a first direction, and
• a second set of a plurality of struts extending in a second direction, the second set of struts overlapping the first set of struts and connected to the first set of struts by pivot elements to define a plurality of circumferentially extending rows of cells,
• wherein each strut is curved along a length of the strut and has first and second longitudinal edges extending along the length, the first longitudinal edge forming a convex curve facing the first end of the frame and the second longitudinal edge forming a concave curve facing the second end of the frame;
• wherein each strut is a unitary member that extends from an inflow end of the frame to an outflow end of the frame;
• wherein the frame has a first diameter at a first end and a second diameter at a second end, and when the frame is in a radially expanded configuration the second diameter is larger than the first diameter;
• and
• wherein when the frame is in a radially compressed configuration the second diameter is smaller than the first diameter.

An implantable prosthetic device, comprising:

• a frame movable between a radially compressed configuration and a radially expanded configuration, the frame comprising a first set of a plurality of struts and a second set of a plurality of struts overlapping the first set and connected to the first set by pivot elements to define a plurality of circumferentially extending rows of cells, each strut being a unitary member that extends from a first end of the frame to a second end;
• wherein in the radially expanded configuration an overall shape of the frame is a tapered frustoconical shape;
• wherein the frame has a first draft angle when in the radially compressed configuration and a second draft angle when in the radially expanded configuration;
• wherein the frame has a first diameter at the first end and a second diameter at the second end, and when the frame is in the radially expanded configuration the second diameter is larger than the first diameter;
• and
• wherein when the frame is in the radially compressed configuration the second diameter is smaller than the first diameter.

An implantable prosthetic device, comprising:

• a radially expandable and compressible frame having first and second opposing axial ends, the frame comprising:
• a first set of a plurality of struts extending in a first direction, and
• a second set of a plurality of struts extending in a second direction, each strut of the second set of struts being coupled to a plurality of struts of the first set of struts to define a plurality of circumferentially extending rows of cells;
• wherein each strut is a unitary member that extends from the first axial end of the frame to the second axial end;
• wherein each strut comprises a non-Euclidian geometry;
• wherein when the frame is in a radially expanded configuration angles formed between pivotably connected struts of each row of cells progressively increase from one end of the frame to the other;
• wherein the frame has a first diameter at the first axial end and a second diameter at the second axial end, and when the frame is in a radially expanded configuration the second diameter is larger than the first diameter;
• and
• wherein when the frame is in a radially compressed configuration the second diameter is smaller than the first diameter.
