1. A stent valve, comprising:
- a scaffold, said scaffold including interlinked struts, said scaffold having a scaffold passageway extending substantially longitudinally therethrough; and
a valve leaflet extending at least partially across said scaffold passageway, said valve leaflet defining a leaflet periphery;
wherein at least a portion of said leaflet periphery extends integrally from at least a portion of at least one of said struts; and
said at least a portion of said leaflet periphery is substantially parallel to said at least a portion of said at least one of said struts.

Abstract
A stent valve includes a scaffold, the scaffold including interlinked struts, the scaffold having a scaffold passageway extending substantially longitudinally therethrough. The stent valve also includes a valve leaflet extending at least partially across the scaffold passageway, the valve leaflet defining a leaflet periphery. At least a portion of the leaflet periphery extends integrally from at least a portion of at least one of the struts and at least a portion of the leaflet periphery is substantially parallel to the at least a portion of said at least one of said struts.

24. A method for manufacturing a stent valve, said method comprising:
-
providing a scaffold having a scaffold passageway extending longitudinally therethrough, the scaffold including interlinked struts;
inserting a mandrel in at least a portion of the scaffold passageway, the mandrel having a valve leaflet forming surface for forming a valve leaflet within the scaffold passageway, the valve leaflet forming surface defining a forming surface peripheral edge, the forming surface peripheral edge including a leaflet-to-strut attachment forming section, the mandrel being inserted in the at least a portion of the scaffold passageway so that the leaflet-to-strut attachment forming section is substantially adjacent and substantially parallel to at least a portion of at least one of the struts; and
forming the valve leaflet by depositing a leaflet forming material onto the valve leaflet forming surface and onto the at least a portion of the at least one of the struts, the leaflet forming material being deposited so that the valve leaflet extends substantially inwardly into the scaffold passageway and integrally from the at least a portion of the at least one of the struts. - View Dependent Claims (25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36)
