Claim Text:
1. A preservation system comprising: a chamber having at least one fluid inlet and an internal volume, the chamber being sized and shaped to allow a body or an organ to be enclosed in the internal volume; a vascular inlet line comprising a needle or cannula, the needle or cannula being constructed for insertion into a portion of a vascular system of the body or the organ; a flow module configured to sequentially deliver at least fixative and liquid carbon dioxide to the chamber through the at least one fluid inlet and to the vascular system through the vascular inlet line; a temperature module configured to control a temperature of the internal volume of the chamber; and a system controller programmed to: control the flow module to fill the chamber and the vascular system with fixative, control the flow module during the filling with fixative such that external surfaces of the body or organ are exposed to the flowing fixative at a same time as the vascular system is exposed to the flowing fixative, control the flow module to fill the chamber and the vascular system with liquid carbon dioxide after the filling with the fixative, and control the temperature module to cool the internal volume to a temperature less than or equal to 10° C. prior to and during the filling with the liquid carbon dioxide.
