Mechanically expandable prosthetic device

A prosthetic valve, comprising:

• a radially expandable and compressible frame having an inflow end, an outflow end, and a longitudinal axis extending from the inflow end to the outflow end, the frame comprising a plurality of struts forming a plurality of cells, each strut comprising a first longitudinal edge and a second longitudinal edge;
• wherein a first subset of struts of the plurality of struts are angled struts and a second subset of struts of the plurality of struts are axial struts that extend in a direction parallel to the longitudinal axis;
• wherein one or more of the axial struts include a first portion having a first width and a second portion having a second width wider than the first width and an aperture extending through a thickness of the second portion from a radially-outwardly facing surface of the axial strut to a radially-inwardly facing surface of the axial strut;
• and
• wherein each aperture is positioned entirely between the first longitudinal edge and the second longitudinal edge of the respective strut.

A prosthetic valve, comprising:

• a radially expandable and compressible frame having an inflow end, an outflow end, and a longitudinal axis extending from the inflow end to the outflow end, the frame comprising a plurality of struts forming a plurality of cells;
• and
• a valvular structure mounted within the frame, the valvular structure comprising a plurality of leaflets each having an inflow end portion and an outflow end portion, wherein adjacent leaflets are connected to each other at the outflow end portions to form commissures of the valvular structure, wherein each commissure is secured to the frame;
• wherein a first subset of struts of the plurality of struts are angled struts and a second subset of struts of the plurality of struts are axial struts that extend in a direction parallel to the longitudinal axis, wherein each axial strut has an inflow end portion connected to a pair of adjacent ends of two angled struts and an outflow end portion connected to a pair of adjacent ends of two angled struts;
• and
• wherein one or more of the axial struts each include a rhombus-shaped portion.
