Sxe the ate 1960S 2 'V-nbc* st Ticthods have been developed of proposed and used lor p'eservafon ol tissue products- These include soiutons containing alcohol high ionc strength of high osmolarity. Most of these methods aim at p'evenlirg the protein components in tissues from s^oslances osed may inhibit subsequent chemical treatment methods or cause complications in SLOsequent processes.

L-Hydro Principles 1. Present (o receptor cells a non viable xenograft matrix (acelular), similar to natural human matrix. 2. Cells grow in same natural function 3. Reconstruction stimulated by similar natural matrix and physiologic conditions In Vivo - tissue engineering." Based or these principles. Labcor in collaboration with Dr. David Cheung, PhD, Heart Institute of Montana5 have developed this method of tissue treatment technology, by the name L-Hydro. Preserve xenog-aft products to be implanted in hLmans as potentially capaole to functonaly reconstruct with no rejection and/or calcification.
