Abstract
A method of processing soft tissue and skin using supercritical fluids is disclosed. The method comprises placing the soft tissue or skin on a scaffold in a processing chamber, adding supercritical fluid to the processing chamber, and pulsing the supercritical fluid in the processing chamber. A processing system for processing soft tissue and skin using supercritical fluids in accordance with the present invention comprises a processing chamber for housing the soft tissue, a scaffold, a vat for storing a processing fluid, a pump, a heating element, and a flow path.
Claims16
A method of processing soft tissue comprising:
- a) providing soft tissue, wherein the soft tissue contains contaminants;
- b) coupling the soft tissue to a scaffold positioned within a processing chamber;
- c) introducing only supercritical CO2 and a degreasing agent into the processing chamber, wherein the degreasing agent is an alcohol or acetone;
- and
- d) performing a pulsing step on the supercritical CO2 and degreasing agent, wherein the pulsing step comprises fluctuating pressure of the supercritical CO2 and degreasing agent, wherein the supercritical CO2 and degreasing agent fluctuates between its supercritical and nonsupercritical states, and wherein the pulsing step kills substantially all the contaminants present within the soft tissue.
A method of processing soft tissue comprising:
- a) providing soft tissue, wherein the soft tissue contains contaminants;
- b) coupling the soft tissue to a scaffold positioned within a processing chamber;
- c) introducing cryogenic CO2 into the processing chamber;
- d) performing a pulsing step on the cryogenic CO2, wherein the pulsing step comprises heating the cryogenic CO2 to a supercritical state, forming supercritical CO2, wherein the supercritical CO2 fluctuates between its cryogenic and supercritical states, and wherein the pulsing step kills substantially all the contaminants present within the soft tissue.
