Liam J. Kelly
Chairman, President and CEO at Teleflex
Thank you, Larry. And good morning, everyone. On this morning's call, we will discuss the first quarter results, review some commercial highlights, and provide an update on our financial guidance for 2024. We had a solid start to 2024 as momentum seen through last year continued into the first quarter. For the quarter, Releflex revenues were $737.8 million, up 3.8% year-over-year on both GAAP and constant currency basis.
First quarter adjusted earnings per share was $3.21, a 3.9% increase year-over-year. During the quarter, utilization for our products trended positively and tracked to our expectations. While we do not expect a revenue benefit from pent-up demand due to the broad exposure of the Teleflex portfolio to critical care procedures, we are seeing utilization back to pre-pandemic levels.
Turning to raw material inflation. We saw positive trends during the first quarter with year-over-year disinflation tracking towards our expectations for the year. Nonetheless, we continue to expect total inflation to be somewhat higher in 2024 as compared to 2023 in part due to inventory capitalized in 2023, impacting the income statement this year. I would also like to provide an update on our logistics and distribution infrastructure. Our freight expenses continue to show positive trends. Despite the conflict in the Middle East, we continue to maintain customer service levels by successfully diverting shipments to alternative shipping lanes. In addition, I would note that we do not utilize the port of Baltimore to ship Teleflex products to or from our North American Distribution center.
Now let's turn to a deeper dive into our first quarter revenue results. I will begin with a review of our geographic segment revenues for the first quarter. All growth rates that are referred to are on a constant currency basis, unless otherwise noted. Americas revenues were $406.3 million, a 1.5% decrease year-over-year. Investors familiar with Teleflex will be aware that prior year MSA revenues were booked in the Americas. EMEA revenues of $159.6 million increased 9.7% year-over-year. Growth was seen across the majority of our product families, including solid double-digit growth contributions from interventional and interventional urology. The region also benefited from the ongoing recovery of ET tubes following the recall last year.
Now turning to Asia, revenues were $84.2 million and a 11.2% increase year-over-year. Revenue growth was broad-based across the region with double-digit increases in China, India, and South East Asia. Let's now move to a discussion on our first quarter revenues by global product category. Commentary on global product category growth for the first quarter will also be on a year-over-year constant currency basis. Starting with Vascular Access, revenue increased 2% year-over-year to $181.4 million. The quarter was led by underlying growth in PICC, Central Access, and EZ-IO, partly offset by the impact of the previously announced endurance catheter recall. We will anniversary the endurance recall during the second quarter and we continue to see opportunities for share gains in the peripheral access market.
Moving to Interventional, revenue was $134.7 million, an increase of 15.4%. year-over-year. We demonstrated growth across our geographic segments as our portfolio of growth drivers continues to perform well. During the quarter, growth was led by balloon pumps, MANTA, and complex catheters. Turning to Anesthesia, revenue increased 3.2% year-over-year to $96.4 million. Growth was balanced across the portfolio. Of note, we continue to recover from the ET tube recall initiated during the second quarter of 2023 and will fully anniversary the revenue comparisons at the end of next quarter.
In our Surgical business, revenue was $105.5 million, an increase of 7.1% year-over-year against a tough comparison. Our underlying trends in our core surgical franchise continue to be solid. Among our largest franchises, growth was led by [Indecipherable] instrumentation and our ligation portfolio. For Interventional Urology, revenue was $79.7 million, representing an increase of 6.1% year-over-year. Growth was driven by Barrigel revenue following the October 2023 acquisition of Palette Life Sciences. And as anticipated, UroLift growth was impacted by continued challenges in the upper side of service and sales force training activities for Barrigel during the quarter.
Our full-year 2024 Interventional Urology total revenue guidance continues to assume approximately 7.5% growth, which continues to incorporate Palette revenues in the range of $66 million to $68 million for 2024. OEM had another solid quarter, with revenues increasing 13.6% year-over-year to $87.7 million. Our three largest product categories recorded double-digit growth in the quarter including continued strength in microcatheters. In addition, we saw some modest benefit from order timing shifting from the second quarter into the first quarter.
First quarter Other revenue declined 27.1% to $52.4 million year-over-year, the decline in revenue on a year-over-year basis is primarily due to the planned December 2023 exit of the MSA by MedLife [Phonetic]. That completes my comments on the first quarter revenue performance.
Turning to some commercial and clinical updates. Starting with an update on Palette Life Sciences, our most recent acquisition. We have now owned Palette Life Sciences for just over six months, and I am pleased to report that the integration process is meeting our targeted milestones. Cross-functional product sales training continued to progress throughout the first quarter. And the first phase of training for our dual-bag reps will be completed at the end of the second quarter.
During the quarter, we were active training and proctoring the legacy UroLift sales force on the use of Barrigel. And we remain on track to fully complete the integration of the sales force by the end of 2024. Moving to a couple of product updates. In our Interventional Access business, we initiated a limited market release of the Wattson Temporary Pacing Guidewire. Wattson will complement our expanding structural hard portfolio which already includes the MANTA large-bore closure device and the Langston dual-lumen for contrast delivery and pressure measurement.
In our Surgical business, we are pleased to share that the Titan SGS Stapler is now available with Gore Seamguard Bioabsorbable Staple Line Reinforcement Material, this complementary pairing supports bariatric surgeons by addressing clinical preferences in the sleeve gastrectomy market. As we look further into 2024, we will continue to advance our new product introductions with a number of launches across our business units. In our Interventional Access business, there is no change to our expectation for an FDA marketing clearance and a limited market release of the Ringer catheter in the second half of 2024. Ringer incorporates a unique balloon design that allows blood to flow through a vessel while the balloon is inflated. We expect to initially launch with a PTCA indication, but will evaluate opportunities for label expansion following the completion of our vessel preparation trial.
Finally, I will provide a regulatory update. In February, we voluntarily initiated a recall of our QuickFlash radial artery and radial artery arterial line catheterization kits after receiving reports of increased resistance in the guidewire handle and chamber during use. The financial impact from this recall was de minimis. In cooperation with the FDA, Teleflex also recently initiated a voluntary field advisory notice for Arrow FiberOptix and UltraFlex intra-aortic balloon catheter kits due to reports indicating an infrequent condition which when not identified and corrected promptly, could result in serious health consequences including a reduction or loss of the hemodynamic support normally provided by intra-aortic balloon pump therapy. The FDA has not yet designated a recall classification, but under the field advisory notice, customers may continue to use the products in scope per additional instructions, warnings and cautions, we expect the financial impact from the voluntary field action to be immaterial. That completes my prepared remarks.
Now I'd like to turn the call over to Tom for a more detailed review of our first quarter financial results. Tom?
