APPARATUS FOR OXYGENATION AND PERFUSION OF TISSUE FOR ORGAN PRESERVATION

摘要

An apparatus (10) according to an embodiment is configured to oxygenate and perfuse a bodily tissue (T) for extracorporeal preservation of the bodily tissue. The apparatus includes a pneumatic system, a pumping chamber (14), and an organ chamber (30). The pneumatic system is configured for the controlled delivery of fluid to and from the pumping chamber based on a predetermined control scheme. The pumping chamber is configured to diffuse a gas into a perfusate and to generate a pulse wave for moving the perfusate through the bodily tissue. The pumping chamber is configured to substantially automatically purge excess fluid from the pumping chamber to an area external to the apparatus. A semi -permeable membrane (20) is inclined from the first side (22) towards the second side (24) of the apparatus in order to direct a rising fluid towards a port (38) disposed at the highest portion of the pumping chamber.
