  "description_excerpt": "The present invention generally relates to a device for transporting a graft and a gripping tool for gripping or holding a graft-transporting device.\n\nIn recent years, new regenerative medicine has been developed as a solution to the treatment of severe cardiac failure. As an example, a method of applying a sheet-shaped cell culture prepared using a temperature-responsive culture dish devised by tissue engineering to the surface of a heart has been attempted to treat severe cardiac infarction, or the like. The method using a sheet-shaped cell culture is capable of safely transplanting a large amount of cells over a wide range, and is particularly effective for, for example, cardiac infarction (including chronic cardiac failure associated with cardiac infarction), dilated cardiomyopathy, ischemic cardiomyopathy, and cardiac diseases (e.g., cardiac failure, particularly, chronic cardiac failure) associated with systolic dysfunction (e.g., left ventricular systolic dysfunction).\n\nIn order to clinically apply such a sheet-shaped cell culture, it is necessary to, for example, store the prepared sheet-shaped cell culture in a container together with a preservation solution and transport the container to an intensive care unit where transplantation is performed. However, the sheet-shaped cell culture inherently has a low physical strength, and thus, is susceptible to wrinkles, tears, damage, etc. that occur due to vibration during the transportation of the container. Therefore, transporting the container requires advanced technique and great care.",
