Abstract
A jacket (10) for keeping a transplant (46) cold during the time the transplant in surgical way is connected to a receiver comprises a wall (12, 14) with a cavity (22) containing a frozen liquid, which melts under absorption of heat from the transplant. Before the transplant is placed in the jacket (10), the liquid, e.g. water, is frozen by being subjected to vacuum, vapour released from the liquid being absorbed by a substance, e.g. zeolite.
