Title:
PERFUSION APPARATUS FOR LIVER FOR TRANSPLANTATION, AND LIVER ISOLATION METHOD AND LIVER TRANSPLANTATION METHOD USING SAID APPARATUS
Document Type and Number:
WIPO Patent Application WO/2017/200089
Kind Code:
A1
Abstract:
With this perfusion apparatus (1) and perfusion method, two perfusion liquid inflow routes (30) and two perfusion liquid outflow routes (40) can be ensured for a liver (9) for transplantation. The perfusion liquid inflow routes (30) each have a perfusion liquid inflow cannula (32) connected to a portal vein or a hepatic artery. The perfusion liquid outflow routes (40) each have a perfusion liquid outflow cannula (42) connected to the upper hepatic inferior vena cava or the lower hepatic inferior vena cava. A perfusion liquid flows into the liver (9) from the perfusion liquid inflow cannulas (32), and the perfusion liquid in the liver (9) flows out from the perfusion liquid outflow cannulas (42). The time during which the liver (9) for transplantation remains in ischemia when the liver (9) is isolated or transplanted can thereby be greatly reduced. Specifically, obstacles to the liver (9) for transplantation can be minimized. The success rate of liver transplantation can thereby be improved. Therefore, during lengthy organ transplant surgery, deterioration of the organ for transplantation during surgery can be prevented.
