Prosthetic heart valve and delivery systems and methods

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

• an expandable outer frame comprising:
• a plurality of outer frame struts intersecting at junctions of the outer frame struts to form closed cells;
• and
• a plurality of downstream tissue anchoring legs configured to extend radially outward from the junctions of the outer frame struts;
• an inner frame situated at least partially within the outer frame, the inner frame comprising:
• a plurality of inner frame struts intersecting at junctions of the inner frame struts to form closed cells;
• and
• a plurality of upstream tissue anchoring arms configured to extend radially outward from the junctions of the inner frame struts;
• and
• a connector pin that (a) is at an intersection of one of the downstream tissue anchoring legs and two outer frame struts that are adjacent to the one of the tissue anchoring legs, and (b) connects the inner frame to the outer frame.

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

• an expandable valve body comprising:
• an outer frame comprising a plurality of outer frame struts intersecting at junctions of the outer frame struts, the outer frame comprises pairs of first and second struts;
• and
• an inner frame situated at least partially within the outer frame and comprising a plurality of inner frame struts intersecting at junctions of the inner frame struts;
• a plurality of tissue anchoring legs, each tissue anchoring leg extending from a junction of the outer frame struts;
• and
• a connector pin that (a) is at an intersection of one of the tissue anchoring legs and two outer frame struts that are adjacent to the one of the tissue anchoring legs, and (b) connects the inner frame to the outer frame.
