1. A valve stent, comprising:
- a supporting net frame having a plurality of grids, with each grid defined by a plurality of struts connected together at nodes, the supporting net frame having opposing first and second frame ends, and with the nodes at each frame end being defined as end nodes; and
a flared section connected to the first frame end of the supporting net frame, wherein the flared section comprises a plurality of supporting bars and a plurality of guiding bars;
wherein each supporting bar has a first supporting bar end and the first supporting bar ends of two adjacent supporting bars are connected to one of the end nodes;
wherein each guiding bar has opposing first and second guiding bar ends, with each first guiding bar end connected to a first one of the end nodes adjacent to a second one of the end nodes where two first supporting bar ends are connected, and each second guiding bar end is connected to a part of the adjacent supporting bar at a location spaced apart from the first supporting bar end;
wherein each supporting bar has a second supporting bar end that is connected to a second supporting bar end of another one of the plurality of supporting bars, andwherein the another one of the plurality of supporting bars is different from the supporting bar to which the supporting bar'"'"'s first supporting bar end shares an end node.
