Abstract
The present invention is directed to a continuous, multi-step dilution process for producing tissue suitable for transplantation into a human from cryopreserved tissue. Cryopreserved tissue is subjected to a continuous flow of wash-out solution following a thawing or simultaneously thawing using the present continuous perfusion chamber. The present continuous perfusion chamber may be rigid or deformable and has an inlet port and an outlet port.
