Prosthetic valve with connecting struts of variable size and tissue anchoring legs of variable size that extend from junctions

An expandable prosthetic valve for implantation within a native mitral valve, the prosthetic valve comprising:

• an expandable annular outer frame including a plurality of struts intersecting at junctions to form closed cells, the annular outer frame further including a plurality of ventricular tissue anchoring legs configured to extend radially outward from the junctions of the annular outer frame;
• and
• an inner frame situated at least partially within the annular outer frame, the inner frame including a plurality of struts intersecting at junctions to form closed cells and a plurality of atrial tissue anchoring arms configured to extend radially outward from the junctions of the inner frame,
• wherein at least one of the ventricular tissue anchoring legs has a cross-sectional area ranging from 0.45 mm2-0.65 mm2 and a strut extending between the at least one ventricular tissue anchoring leg and an adjacent ventricular tissue anchoring leg has a cross-sectional area ranging from 0.15 mm2-0.30 mm2;
• and
• wherein a connector pin is situated at an intersection of the at least one ventricular tissue anchoring leg and two adjacent struts of the expandable annular outer frame.

An expandable prosthetic valve for implantation within a native mitral valve, the prosthetic valve comprising:

• an expandable valve body formed from a plurality of struts intersecting at junctions and including an annular outer frame and an inner frame situated at least partially within the annular outer frame;
• and
• a plurality of tissue anchoring legs extending from the junctions of the valve body,
• wherein at least one of the tissue anchoring legs has a cross-sectional area ranging from 0.45 mm2-0.65 mm2 and a first strut extending from the at least one tissue anchoring leg toward an adjacent tissue anchoring leg has a cross-sectional area ranging from 0.15 mm2-0.30 mm2,
• wherein the at least one tissue anchoring leg and the adjacent tissue anchoring leg are angularly separated by a single junction;
• and
• wherein a connector pin is situated at an intersection of the at least one tissue anchoring leg and two adjacent struts of the annular outer frame.
