ISRG Sees 91% SP Growth: A Turning Point for Single-Port Surgery?

Core Insights - Intuitive Surgical's single-port (SP) platform is emerging as a significant growth driver, with SP procedures increasing by 91% year-over-year in Q3 2025, surpassing overall da Vinci growth and indicating strong adoption, especially outside the U.S. [1][12] Adoption and Utilization - The highest adoption rates are observed in Korea, where SP utilization has surpassed that of the legacy Xi system, indicating a shift from novelty to routine clinical use [2][12] - In the U.S., SP adoption is in its early stages, but the market is expanding with initial domestic use of the SP stapler in colorectal and thoracic procedures, which are substantial procedural categories [4][12] Clinical Evidence and Regulatory Developments - Management highlighted growing clinical evidence that SP offers patient benefits beyond cosmetic outcomes, potentially improving recovery times and length of hospital stays, which could influence adoption among surgeons and hospital administrators [3] - Regulatory momentum is crucial, with completed U.S. regulatory submissions for nipple-sparing mastectomy and other general surgery indications, aiming to replicate Korea's adoption curve in the U.S. market [5] Strategic Considerations - The key question for investors is whether SP will serve as an incremental growth driver or primarily replace multiport da Vinci volumes. Management suggests that SP's unique features may enable minimally invasive surgery in patient populations not well served by multiport systems [6] - Although SP currently contributes modestly in absolute terms, its growth trajectory indicates a potential transition from niche to mainstream, contingent on continued regulatory expansion and clinical evidence [7] Peer Updates - Stryker's robotic surgery segment showed strong momentum, achieving record Mako installations and expanding usage across various surgical cases, supported by software enhancements [8] - Globus Medical's robotics and navigation ecosystem is scaling, with the launch of ExcelsiusXR, a wearable navigation headset aimed at improving surgeon focus and ergonomics [10]
