Prosthetic heart valve for multiple positions and assembling method thereof

A prosthetic heart valve, comprising:

• a universal core, adaptable for different application scenarios, comprised of a ring-shaped stent, having a distal end and a proximal end in an axial direction, and comprising:
• a mesh structure as a circumferential sidewall, which allows the stent to be contracted or expanded in a radial direction, wherein the stent is configured to have blood flow from the proximal end to the distal end;
• and
• a plurality of cantilever struts, having various length, each of which extends distally from the proximal end of the mesh structure;
• a leaflet structure comprising a plurality of leaflets, each of which is attached to the stent and at least has a portion disposed within the stent, wherein the leaflet structure allows blood to flow from the proximal end to the distal end through the prosthetic heart valve and inhibits blood flowing from the distal end to proximal end through the prosthetic heart valve;
• a designated adapter, which is selected from more than one adapters suitable for the different application scenarios and configured to anchoring the stent at a target position, wherein the stent and any one of the more than one adapters are detachably connected with each other based on the plurality of cantilever struts,
• wherein the plurality of cantilever struts, which are softly connected by a wire to form a supporting structure for the leaflet structure, are each configured to move in at least three degrees of freedom.
