ABSTRACT:
A method for repairing a heart valve comprising steps of sizing an annulus of a heart; harvesting tissue; cutting a trefoil pattern matched to the size of the annulus from the harvested tissue; forming a valve having at least one leaflet from said trefoil pattern, where the valve has a base with an edge portion of tissue extending around an outer periphery thereof; and suturing the edge portion to the exposed annulus; also disclosed is a method of repairing a heart valve comprising steps of: sizing an annulus of a heart at a repair site; harvesting tissue; cutting a trefoil pattern from the harvested tissue specific to the size of the annulus; providing first and second formers which are specific to the size of the annulus of the valve, forming a tri-leaflet valve from said trefoil pattern by engaging blades of said first former to corresponding blades of said second former with said trefoil pattern sandwiched therebetween; exposing an edge portion of tissue extending around an outer periphery of a base of the valve; moving the formers with the trefoil pattern sandwiched therebetween to a position which is proximate to the repair site; suturing the exposed edge portion to the annulus; and withdrawing the formers from the repair site.
