David J. Rosa
President and Member of the Board of Directors at Intuitive Surgical
Thank you, Gary. Starting with procedures, da Vinci procedure growth in the quarter was 18%, aided by an additional business day relative to Q3 2023. Growth again centered on general surgery in the U.S., with accretive contributions to the global growth rate from Japan, Germany, France, and the U.K. In Asia, we have mixed market conditions largely consistent with the first half of the year. Jamie will describe these dynamics later in the call.
Turning to capital. We placed 379 da Vinci systems in the quarter, including 110 da Vinci 5 systems and 21 SP systems. We also installed 58 Ion systems in the quarter. Capital placements were solid in the U.S., Japan, India, and our distribution markets, and capital pressure in Europe and China continued. System utilization, defined as procedures for installed clinical system per quarter, grew 4% globally year over year for our multi-port platforms, 9% for SP, and 11% for Ion.
Turning to our finances. Revenue grew 17% in the quarter and spending was within our expectations. Our spending reflects investment in research and development to support the growth of our platforms and digital tools, expansion of our manufacturing facilities, and planned leverage from our enabling functions. Jamie will take you through our finances in greater detail later in the call.
In Q3, we continued our measured rollout of da Vinci 5, placing 110 systems, as the launch progresses in line with our plans. We are encouraged by broad use of the platform across specialties, with customers expressing a preference for da Vinci 5. Last month, about 1,200 healthcare professionals gathered at our annual user conference, Intuitive 360, to highlight various aspects of their robotic programs. Customers have completed over 12,000 cases with da Vinci 5, and several presented their early case data around efficiency and force feedback. A number of customers have reported consult time savings when comparing da Vinci 5 to Xi, and we look forward to broader analyses as more data becomes available.
For force feedback, Dr. Laila Rashidi from MultiCare Health in Tacoma, a leading voice on gentler surgery and its impact on recovery for her colorectal patients, described her results. Even with her focus on managing surgical forces, Dr. Rashidi's initial cases with da Vinci 5 show a further reduction in force of about 20% when force feedback is used. Force feedback is a complex technology that we have been pursuing for more than two decades, and it stems from a belief that less force on tissue can lead to improved patient experiences. We also believe force feedback may accelerate learning for care teams, and we will continue to study the use of force feedback with our customers. We expect more publications over the coming quarters, and our teams continue working hard to improve product margin and increase supply of force feedback instruments. As we have said before, maturing these insights will take time.
Turning to our digital efforts. We believe that digital innovations on our da Vinci and Ion platforms can extract unique clinical and operational insights. Coupled with electronic medical record data, these insights should become a core part of improving outcomes, learning, and efficiencies in the future. To date, we have data from millions of procedures that enable customers to review operational metrics, such as instruments used, procedure duration, and more. In addition, hundreds of thousands of these cases are connected to corresponding deidentified electronic medical records, enabling certain clinical and operational hypotheses to be tested.
Case Insights is our new analytical tool in My Intuitive that will add kinematic, force feedback, and video data to physicians' post-operative case reports, further enabling analyses to identify a connection between da Vinci system data and clinical or operational outcomes. We are at the early stages of innovative technology we believe will be powerful. But it will require rapid cycles of innovation and take time to build validated data sets.
In Q3, we submitted our CE technical file in Europe. Last week, we received clearance for da Vinci 5 in Korea and are back and forth in the regulatory process in Japan. This quarter, we began shipping our da Vinci 5 broad launch hardware and completed a software update that addresses aspects of early customer feedback. We are driving toward broad launch midyear of 2025, when we expect to be at scale in our manufacturing operations, and we'll have released a software update enabling the integrated hub and simulator, along with various digital and imaging features.
Moving to instruments and accessories. In Q3, we obtained 510(k) clearance for our 8-millimeter SureForm 30 Stapler, expanding our advanced instrument portfolio of SureForm staplers, that currently includes 12-millimeter versions of 60-, 45-, and 30-millimeter lengths. 8-millimeter SureForm 30 is primarily used in cases where the decreased diameter enables surgeons to better visualize and access tissue in tight spaces, as often seen in thoracic or kidney procedures.
We are starting our commercial journey in China with Ion, where we placed two systems and saw physicians perform their first cases. We will begin working with a number of medical centers to collect data that will inform our broader commercialization strategy in the country. In Europe, our early launch expanded into Germany and Italy.
Turning to SP. In the quarter, we received clearance with broad indications in Taiwan, similar to Korea, Japan, and Europe. We also completed a U.S. 510(k) submission for a colorectal indication. Commercialization in Europe continues according to plan. And we're encouraged by early customer interest for SP.
Now I'd like to share with you some recently published peer-reviewed literature that we found to be notable. In addition to the specific data highlighted on this call, we encourage you to consider the wide body of evidence detailing these topics in published scientific studies over the years.
In August, at the 2024 American Association for Bronchology and Interventional Pulmonology Annual Conference, Dr. Bryan Husta from Memorial Sloan Kettering Cancer Center presented results from the CONFIRM study. CONFIRM is a prospective multicenter study evaluating outcomes from the integrated Ion endoluminal system and mobile cone beam CT in the biopsy of pulmonary nodules less than 2 centimeters in size. 155 patients from six centers throughout the U.S. were enrolled. With a median nodule size of 14 millimeters, the integrated platform enabled a tool and nodule rate of 99.4%, with a diagnostic yield of 90% and zero pneumothorax observed. Subgroup analysis demonstrated consistent results across all centers, with high diagnostic yields observed regardless of nodule size, location, or presence of CT bronchus sign.
The presented conclusion noted, "Integrated shape-sensing robotic-assisted bronchoscopy and mobile cone beam CT demonstrated a high diagnostic yield and excelled safety for small complex nodules with reproducible results across physicians and institutions. These results suggested that integrated platform may be able to compete with a transthoracic biopsy approach in small nodules."
Earlier this year, Dr. Maegawa from the Department of Surgery at Emory University in Atlanta, Georgia, published in the journal Surgery, a study comparing robotic and laparoscopic cholecystectomy procedures for benign indications performed in 2022. Using the American College of Surgeons National Surgical Quality Improvement Program database, over 59,000 patients were included in this study, with over 53,000 in the laparoscopic arm and approximately 5,500 in the robotic-assisted arm.
Through a multi-variable logistic regression analysis, which controlled for confounding factors, patients undergoing a robotic-assisted cholecystectomy had an 18% lower chance of experiencing a serious complication, as well as a 56% lower chance of a conversion to open, and 24% lower risk of requiring hospitalization for more than 24 hours.
The authors also looked at elective cholecystectomies only and reported a 46% lower chance of conversion to open, 59% lower chance of reoperation, and 30% lower odds of hospitalization over 24 hours associated with robotic-assisted cholecystectomies. The authors concluded, "Using a large and recent national surgical database, the study showed that overall, robotic cholecystectomies were independently associated with a lower risk of serious complications, lower rate of conversions to open, and lower risk of hospitalization greater than 24 hours when compared to laparoscopy. These findings suggest that the adoption of new technologies might enhance the safety of minimally invasive surgery in selected cases."
In closing, we are committed to our 2024 priorities: supporting our measured launch of da Vinci 5 and our other new platforms by region; supporting surgeons' adoption of focus procedures; continuing to improve product quality and margins; and finally, improving productivity in those functions that benefit from global scale.
I'll now turn the time over to Jamie, who will take you through our finances and procedure highlights in greater detail.
