Abstract

Medical material and a method for preparing a biological tissue for a medical application are provided. The material is useful as a sealing element in a heart valve prosthesis. A method includes decellularizing the biological tissue by decellularizing solution to obtain an acellular extracellular matrix, solubilizing the extracellular matrix of the biological tissue, and crosslinking collagen fibers of the solubilized extracellular matrix.
