The effects of cryopreservation on the biological tissue mechanics are still largely unknown. Generalized Maxwell model was applied to characterize quantitatively the viscoelastic behavior of sheep mitral heart valve tissue. Three different groups of specimens are supposed to be tested: fresh tissue specimens (control group), cryopreserved allografts from tissue bank and allografts already used as tissue replacements taken from the animals approximately one year after the surgery.

At the moment, only the first group of specimens was examined. The methodology presented in this paper proved suitable to complete the study.
