The present invention relates to an apparatus for use in processing "raw" pericardium. The apparatus comprises of a mold having a generally hemispheroid dome and a support base upon which the mold is mounted. The hemispheroid dome has a diameter suitable for stretching a pericardium over the dome. The invention also relates to a method for processing "raw" pericardium. The method involves stretching raw pericardium over a mold such that the pericardium conforms to the shape of the mold and the mold stretches the pericardium. This is followed by separating at least some of the fat layer off the pericardial tissue layer where the pericardium is mounted over the mold and finally removing fat from the total pericardium surface.
