SYSTEM AND METHOD FOR MAPPING AND MARKING THICKNESS OF BIO-PROSTHETIC SHEET

PROBLEM TO BE SOLVED: To provide a system and a method which characterize a material used for the production of a heart valve leaflet, especially, a pericardial tissue promptly and certainly. SOLUTION: This is a method of the stock management of a biological material for the use of a graft. This method includes the following processes; a process to provide the stock supply amount of the biological material; a process to measure the thickness of two or more points of two or more flat extended elements of the biological material from this stock supply amount; a process to put this measured thickness into a computer; a process to provide the data on the desirable thickness of the flat element of the biological material for this graft to this computer; and a process to carve this flat extended element of the biological material into a separate zone based on the data of the measured thickness and the desirable thickness and to control the number of the separate zone of the desirable thickness cut off from this stock supply amount.
