Abstract
An implant for supplementing, repairing, or replacing a native heart valve leaflet or leaflets provides a scaffold, which defines a pseudo-annulus. The implant further has at least two struts in generally oppositely spaced apart positions on the scaffold. The scaffold can be placed in an elastically loaded condition in a heart with the struts engaging tissue at or near the leaflet commissures of a heart valve annulus, to reshape the annulus for leaflet coaptation. The implant further provides a neoleaflet element coupled to the scaffold within pseudo-annulus, to provide a one-way valve function.
