Abstract
An arrangement for preparing natural tissue in the form of a heart valve, vessel or the like for implantation in which tanning fluid under pressure is applied to a portion of the tissue so as to cause said tissue to assume substantially its natural configuration, while additional tanning fluid is applied to the remainder of the tissue, said tanning fluid being so applied for a time sufficient to cause the tissue to become fixed, and, for vessels or the like, a guide may engage the tissue during fixation, whereby said tissue maintains substantially the configuration of the guide.
