Dr Heden is one of the world's leading experts on breast augmentation and facial aesthetic surgery with experience of performing nearly 16,000 breast augmentation procedures.
Mr Oliver and colleagues were invited to visit Dr Heden in Stockholm and he assisted him with a breast augmentation case, as the photograph shows.
On returning to the UK, Mr Oliver said "Whatever your experience there will always be a little more to learn in order to refine and improve your results further".
