Before inserting and expanding a pen-sized stent into someone’s aorta, the hose-like artery that carries our blood away from the heart, surgeon Jason Chuen likes to practice on the patient first. Not for real of course, but in plastic.
Which explains the 3D printer in his office and the brightly coloured plastic aortas that line his window sill at the Austin Hospital in Melbourne. They are all modelled from real patients and printed out from CT scans, ultrasounds and x-rays.
“By using the model I can more easily assess that the stent is the right size and bends in exactly the right way when I deploy it,” says Mr Chuen, Director of Vascular Surgery at Austin Health and a Clinical Fellow at the University of Melbourne.
