“Twenty years ago, surgical and engineering came together to address clinical need in the operating room. This collaboration of engineering and clinical expertise was the secret to success with the development of the Endoflex™ retractor.
Over the years we have maintained this surgeon-led focus and have been fortunate enough to have created a Clinical Advisory Board (CAB) made up of some of the most prominent and expert surgeons the UK has to offer. The CAB works closely with our design team; offering clinical feedback on our innovative existing product portfolio and also giving inspiration for new ideas
I’m proud to be a founder of SI and look forward to developing new ideas with SI’s design team over the coming years; ensuring SI’s surgeon-led philosophy is continued.”
