ABSTRACT:
A method for making a bioprosthetic heart valve includes providing a non-contact cutting apparatus and a layer of tissue. The non-contact cutting apparatus may include a laser cutting system or high pressure water jet system. A leaflet is cut from the layer of tissue using a predefined template, and a plurality of alignment holes in the leaflet are created in the leaflet, e.g., along a peripheral edge. A support structure is provided having a plurality of alignment holes corresponding to alignment holes in the leaflet. The leaflet is secured to the support structure by securing one or more sutures through corresponding alignment holes in the leaflet and the support structure to provide a leaflet subassembly. A bioprosthetic heart valve is made by securing a set of leaflet subassemblies to a frame.
