1. **Increased Da Vinci System Placements**: The company placed 379 da Vinci surgical systems in Q4 2024, including 110 da Vinci 5 systems. This reflects strong market adoption and a 15% increase in the installed base to 9,539 systems.
2. **Growth in Da Vinci and Ion Procedure Volumes**: Instruments and Accessories revenues grew by 18% to $1.26 billion, driven by increased da Vinci and Ion procedure volumes. Worldwide da Vinci procedures grew by 18% compared to the same quarter last year.
3. **Improved Pricing**: Systems segment revenues increased by 17.4% year-over-year, totaling $445 million. This was partly due to higher pricing for systems.
