Organ transplantation is now a well established life saving procedure for patients suffering from end-stage disease of various organs. In the last four decades, the concept of "brain death", a state where the brain is irreversibly damaged but the heart is beating, has been legalised and accepted in many countries of the world. A majority of transplants are now done with organs retrieved from such brain dead individuals. The need for organs, however, far outweighs their availability and a large number of patients still die waiting for organs.
