Abstract
A prosthetic valve for catheter delivery is disclosed. The prosthetic valve comprises a valve assembly having an inlet, a plurality of leaflets and commissural points. The prosthetic valve also includes a support stent comprising a web-like construction and plurality of longitudinal support beams. The support stent is configured to be collapsible for percutaneous delivery through a blood vessel and expandable to contact the the native valve. The support stent supports the inlet of the valve assembly and the commissural points of the valve assembly are secured at the longitudinal support beams. The longitudinal support beams comprise a plurality of bores and the leaflets are secured to the longitudinal support beams via threads passing through the plurality of bores.
