Intuitive Surgical vs Danaher: Which Is the Better Buy in 2026?

Intuitive Surgical earns the large majority of its revenue from instruments and accessories consumed in each da Vinci procedure — not from system sales. That means revenue grows with procedure volume regardless of whether hospitals are buying new systems. Danaher earns from selling scientific instruments, diagnostics equipment, and water quality tools to labs, biotech companies, and utilities. ISRG's revenue is tied to surgical procedure growth; Danaher's is tied to research lab spending, biotech funding cycles, and diagnostic test volume.

Intuitive Surgical's installed base flywheel is one of the strongest recurring revenue mechanisms in medical technology — once a hospital trains surgeons on the da Vinci system, switching to a competitor requires retraining an entire surgical team, which creates switching costs that compound the installed base value every year. Danaher's business is excellent but its value is primarily in its Danaher Business System operating discipline applied across a diversified portfolio of life sciences tools. ISRG for a specific, highly defensible product franchise with strong procedure growth; DHR for a management system applied across a broader portfolio.
