Currently, the robotic surgical market is dominated by Intuitive Surgical ( ISRG 2.32% ). The maker of the da Vinci surgical system has more than a one-decade head start over its peers, and in just the second quarter alone, it wound up shipping 130 da Vinci systems to clients. Worldwide, Intuitive Surgical had 3,745 da Vinci systems installed as of the end of June 2016 compared to one ALF-X surgical robotic system. It's going to take time for its competitors to take a notable bite out of its leading market share. However, TransEnterix could do it with some help.
