1. The method of preparing for implantation natural tissues in a form in which a portion thereof is subjected to pressure within the physiologic range when implanted and which assumes a predetermined configuration as a result of such pressure comprising the steps ofalternately applying a tanning fluid to said portion of said tissues at a pressure within the physiologic range, and relieving the pressure on said portion of said tissues to less than that of said physiologic range,whereby said portion of said tissues is caused to assume said predetermined configuration intermittently,and simultaneously applying a tanning fluid to remaining parts of said tissues at a pressure below said physiologic range so as to cause said portion and said remaining parts of said tissues to become fixed while said portion of said tissues intermittently assumes said predetermined configuration.
