Imagine you are Martin Birchall, laryngologist and ENT surgeon, star of regenerative medicine at UCL and trachea transplant enthusiast. You and your business partner Videregen need to explain to EU bureaucrats why your technology of decellurised cadaveric trachea is perfectly safe, what with all the dead patients of yours and your former best friend Paolo Macchiarini. Yet both your trachea transplant pigs die. EU authorities however accept this as proof that your method is safe!
