Prosthetic heart valves with expansion and locking assemblies

A delivery assembly, comprising:

• a prosthetic valve comprising:
• a frame movable between a radially compressed and a radially expanded configuration;
• at least one expansion and locking mechanism comprising:
• an outer member having an outer member first end and an outer member second end, wherein the outer member is coupled to the frame at a first location;
• an inner member having an inner member first end and an inner member second end, wherein the inner member is coupled to the frame at a second location spaced apart from the first location, and wherein the inner member extends at least partially into the outer member;
• and
• at least one plate comprising a primary aperture, disposed around the inner member, the at least one plate configured to transition between an angled locking orientation and a non-locking orientation;
• a delivery apparatus comprising:
• a handle;
• a delivery shaft extending distally from the handle;
• and
• at least one actuation assembly extending from the handle through the delivery shaft, and detachably coupled to the at least one expansion and locking assembly;
• wherein the frame is movable from the radially compressed configuration to the radially expanded configuration upon actuating the at least one expansion and locking assembly by the at least one actuation assembly;
• wherein movement of the inner member in a first direction, relative to the outer member, causes the frame to foreshorten axially and expand radially in a non-locking orientation of the at least one plate;
• wherein in the absence of a force applied to the plate in the first direction, movement of the inner member in a second direction, relative to the outer member, causes the at least one plate to assume the angled locking orientation;
• and
• wherein the at least one plate is configured to inhibit advancement of the inner member in the second direction relative to the outer member, when oriented in the angled locking orientation.

• and
• wherein the release member is configured to transition the at least one plate to the non-locking orientation, and/or retain the at least one plate in the non-locking orientation, when the release member is pulled by the release assembly in the first direction relative to the outer member.
