SHANGHAI – The 93rd China International Medical Equipment Fair (CMEF) wrapped up last week. Walking the floor for four days at Booth 5.2Q60, one thing was obvious: peripheral vascular intervention isn't the quiet corner of medtech anymore.
The numbers back it up. The global interventional cardiology and peripheral vascular devices market hit USD 27.7 billion in 2025 and is projected to reach USD 60.8 billion by 2035, growing at 8.2% annually. The broader interventional cardiology devices market-coronary balloons, catheters, sheaths-is expected to grow from USD 29.41 billion in 2025 to USD 42.39 billion by 2031, a 6.4% CAGR.
For those of us making the tools, these aren't just numbers. They're a signal.
We spent the week talking with clinicians, distributors, and procurement folks from all over. Three topics kept coming up.
Trend 1: PTA balloons need to do more
A decade ago, a balloon that got to the lesion and dilated it was good enough. Not anymore.
The PAD treatment landscape is shifting. New clinical data-including the SirPAD trial presented at ACC.26 and published in the New England Journal of Medicine-showed sirolimus-coated balloons cut major adverse limb events to 8.8% versus 15% with uncoated balloons at one year in an all-comers patient population. Nearly 50% of enrolled patients had acute or chronic limb-threatening ischemia. This isn't niche research.
What does that mean for device manufacturers? Coatings aren't optional extras anymore. They're becoming the baseline. Whether it's drug-coated balloons for complex lesions or high-performance uncoated balloons for straightforward cases, the expectation is the same: predictable expansion, minimal vessel trauma, consistent performance across a range of anatomies.
Trend 2: AI and robotics are changing the procedure room
This year's CMEF theme was "Innovation Convergence, Infinite Leap" . The big story wasn't just the hardware on display-it was how AI and robotics are changing the way devices get used.
On the show floor, pan-vascular interventional surgical robots were demonstrating millimeter-level precision. Meanwhile, AI diagnostic agents that can detect multiple conditions from a single image are moving into clinical practice.
What does that mean for device makers? When robotic systems handle navigation and positioning, catheter trackability and pushability become even more critical. When AI helps assess lesions, the demand for balloon sizing that matches lesion characteristics only increases. Devices don't work in isolation anymore. They work inside an ecosystem.
Trend 3: OEM partnerships are moving faster
Maybe the most practical takeaway: distributors and device brands aren't just looking for products. They're looking for manufacturing partners who can move quickly.
One conversation at our booth started with a question about balloon diameters. Ten minutes later, we were talking about custom catheter lengths, multi-valve folding options, and regulatory pathways for a new market. That's the reality of today's supply chain-especially as more companies look to diversify sourcing outside traditional manufacturing hubs.
The shift toward regionalized supply chains means medical device OEMs are actively looking for qualified partners in Asia. For contract manufacturers with GMP-certified cleanrooms and proven quality systems, this creates real opportunities. The key is responding fast without cutting corners on compliance.
What this means for us
We've been making balloon dilatation catheters and sheaths for coronary and peripheral applications since 2015. Our facility is 5,000 square meters, GMP-compliant, Class 100,000 cleanroom with local Class 100 areas. We hold CE certification and ISO13485. Our core team brings over 15 years of experience from internationally recognized medical device firms.
But here's what actually matters: we're listening. The three trends above are already shaping how we develop new products, refine existing ones, and support OEM partners. If you missed us at CMEF-or if you were there and want to keep the conversation going-reach out.
The field is moving fast. We're building for what comes next.
