Intuitive Surgical is the dominant company in robotic-assisted surgery and one of the most commercially successful robotic-arm companies in any sector. Its da Vinci systems use multiple robotic arms controlled by surgeons to perform minimally invasive procedures. The company is relevant to a broad robotic arms market because it proves that high-value manipulation can create a major recurring ecosystem of hardware, instruments, training and services. Intuitive's business model and installed base make it the benchmark for surgical robotics.
