In a truly ironic stroke of fate, John Cousins was giving a presentation about the merits of using 3D printed models to a hospital when he collapsed mid-discussion. Upon being transported to another hospital, Cousins, the managing director of isodo3D was able to 3D print a model of his own kidney for doctors to use during the procedure to remove a large kidney stone. The mode actually helped to speed the procedure along, and acted as a perfect case study for the technology that Cousins had been pitching all along.
