Geoff Martha
Chairman and Chief Executive Officer at Medtronic
Hello, everyone, and thank you for joining us today. We are pleased with the strong start of our fiscal year. We executed and delivered another quarter of mid-single digit organic revenue growth. Our solid results were broad-based with each of our four segments delivering 6% growth driven by execution, innovation, and much improved underlying fundamentals in our markets and supply chain. We also continue to make great strides on our comprehensive transformation, which is designed to get at the root of what has held back our growth. We're executing large-scale functional improvements to global operations, supply chain and quality.
And we're also decisively allocating capital, particularly to our programs and fast secular growth markets, as well as focusing our R&D investments on technology megatrends like robotics and artificial intelligence that will drive growth in our industry over the next decade. And at the same time, we remain focused on our ongoing portfolio management efforts. And taken together, we expect this continued focus on executing our transformation will ensure durable top and bottom line growth and create value for our shareholders.
So, let's turn now to the details of our Q1 results. We had another strong quarter of growth from our largest businesses: Cranial & Spinal, Surgical and Cardiac Rhythm. These businesses have durable established leadership positions. And combined, they made up just under half of our revenue and grew 6% organic.
Starting with Cranial & Spinal Technologies, we had another great quarter, growing 6% globally and 8% in the US, driven by our market-leading Aible ecosystem. We're seeing growth in both neurosurgery capital equipment and the associated pull-through of our best-in-class spinal implants and biologics as surgeons continue to adopt Aible. Neurosurgery grew 5%, including double-digit growth in Mazor Robotics and high-single digit growth in StealthStation Navigation. And Spine & Biologics grew 7% globally and 9% in the US. These results demonstrate our successful strategy of offering surgeons a differentiated and innovative ecosystem including our AI-enabled surgical planning platform and patient-specific customized implants, along with imaging, navigation and robotic technologies.
Now, moving to Surgical, we grew 7%. Supply continued to improve and this drove high-single digit growth in Advanced Surgical Technologies. And we had particular strength in Advanced Energy as we continue the rollout of our LigaSure XP and cordless Sonicision 7.
Cardiac Rhythm grew 5% with mid-single digit growth in Defibrillation Solutions, Diagnostics and Cardiac Pacing. And now with in-pacing, we had strong mid-teens growth in our Micra leadless pacemaker franchise and we launched our next-generation microdevices AV2 and VR2 in the US. These tiny 0.8 cc devices have a battery life of 16 and 17 years, respectively; 40% longer than our previous generation and well beyond average battery life of competing products. We're also seeing EPs rapidly adopt conduction system pacing as an alternative to traditional single or dual-chamber pacing. Our 3830 lead is the only one approved for conduction system pacing in the US and it grew 45% in the quarter.
Looking ahead, we're preparing to launch the Aurora EV-ICD later this year. Aurora is a game-changer for the ICD space. It delivers the benefits of a traditional ICD including the same size, longevity and pacing features, but without leads in the heart or veins.
Turning to our Synergistic businesses, there were several notable performances this quarter. Cardiac Surgery grew 8% again this quarter with strength in Perfusion and Cannula. Our Aortic and ENT businesses, both grew double-digits, driven in part by improved product availability. Peripheral Vascular grew mid-single digits with low-double digit growth in drug-coated balloons and high-single digit growth in superficial vein therapy. Neuromodulation grew mid-single digits in both Pain Stim and Brain Modulation, driven by new implants of Intellis with DTM and Percept PC with BrainSense.
And just last week, we received CE Mark approval for our next-generation spinal cord stimulator, Inceptiv, which will be available in Europe in the coming months. Inceptiv incorporates closed-loop therapy with e-caps, the result of decades of Medtronic R&D to unlock the ability to listen and respond to signals along spinal cord. Both our largest and synergistic businesses had really strong quarters and our businesses that compete in high secular growth MedTech markets they did as well. All combined, these businesses made up 20% of our revenue and grew in the high-single digits in Q1. We continue to disproportionately invest in these businesses, and we expect them to become a larger part of our revenue mix and be large contributors to our durable growth in the future.
Starting with Structural Heart. Transcatheter valves grew 11% globally, including 12% growth in the US and 21% growth in Japan. We continue to see improvements in the TAVR space and adoption of our differentiated Evolut FX valve. Evolut FX combines enhanced and predictable valve deployment with industry-leading durability. And next Monday, we're looking forward to the presentation of the notion 10-year data at ESC, which will look at the durability of the CoreValve and Evolut valves compared to surgery over a decade.
In Neurovascular, we grew mid-single digits when you exclude China, where the market is subject to volume-based procurement. Global growth was fueled by continued strength and flow diversion. We're seeing strong adoption of our Shield Technology for treating aneurysms, which is available on our Pipeline Flex and Pipeline Vantage flow diverters.
And Cardiac Ablation Solutions grew 5%. And as you know, Pulse Field Ablation has become one of the most anticipated technologies in MedTech and we will be leading the way in bringing PFA catheters to market for both focal and single-shot segments. We're continuing the limited market release in Europe for our Affera mapping and ablation system including our Sphere-9 focal catheter. Sphere-9 can perform both PFA and RF Ablation and delivers high-density mapping all from the same catheter.
Turning to our single-shot PFA catheter, PulseSelect. We filed for approval with US FDA and expect to be one of the first companies with a PFA catheter in US market. With our PFA catheters and the Affera map/nav system, combined with our leading Arctic Front cryo solution and differentiated AcQCross Transseptal Access System, we're poised to become a more meaningful player in the fast-growing $8 billion EP ablation space.
In robotic surgical technologies, we increased our installed base as we continue the international rollout of our differentiated Hugo robotics system. And we've activated new sites in our Expand URO US pivotal trial, which continues to progress to plan. We expect Hugo to be a meaningful growth driver for us in the years ahead, given its differentiated value proposition, our leading position in minimally-invasive surgery and the low penetration of robotic surgery around the world.
And in Diabetes, we had a good quarter as we continue to see very strong demand for the MiniMed 780G AID system in markets around the world. 780G is a true second-generation AID system and is the only one with five-minute adjustments and auto-corrections and meal-detection technology. We're getting great feedback that users are feeling a difference within one to two days. And our real-world evidence indicates that 90% of users are achieving or exceeding their glycemic targets when using our recommended settings, as well as getting burden reduction in their diabetes management. And this differentiated value proposition is showing up in our results. Non-US developed markets grew 18%, our highest growth in four years driven by both 780G adoption and increased CGM attachment rates.
And in the US, we're seeing great results and momentum from the 780G launch. First, the launch drove low-30s growth in our US durable pump sales. Second, we're seeing our prescriber base rapidly expand. Since we last talked to you at ADA in late-June, we've had a 30% increase in unique prescribers, with now over 13,000 since launch. Third. We've had over half of our 770G installed base upgrade or place an order for the 780G since launch. And not only is demand coming from our existing installed base, but we're also getting competitive conversions. And finally, we're seeing very high CGM attachment rates in the 780G installed base, which will drive our economics and gives us confidence in accelerating growth.
So the turnaround in diabetes is real and underway. And I am pleased with the progress the team is making. And we're just at the beginning of this inflection point for the business. As we shared with you at our ADA investor briefing in June, we see the intensive insulin space moving from primarily standalone CGM today to one that is smart dosing through either AID systems or smart MDI and we are well-positioned for this trend. We continue to invest heavily in next-generation durable pumps, smart pens, patch pumps, sensors and algorithms, with multiple programs under development. And importantly, we're the only company assembling this complete ecosystem of differentiated technology for people living with diabetes.
With that, I'll turn it over to Karen to discuss our financial performance and our fiscal '24 guidance raise. Karen?
