The Making of Merit Medical—A Timeline Celebrating 35 Years

This year, we’re celebrating 35 years of Merit Medical, an organization founded with a vision to be the most customer-focused company in healthcare. Since then, we’ve expanded from our headquarters in Salt Lake City, UT, to facilities across the world with a diverse, ever-growing portfolio of products.

As with any great business, we couldn’t have done it alone. Our team is at the heart of what we do. We understand clinician needs and innovate products to meet those needs. We deliver diagnostic and treatment solutions that work. Above all, we help ensure our healthcare partners have what they need to help patients live their best lives.

Let’s look back at some of the pivotal moments that made us Merit.


Our story begins more than three decades ago in an industrial park in Murray, UT. Fred Lampropoulos, Merit’s founder and CEO, brought his idea of a stronger, safer, disposable syringe to life—replacing glass syringes currently used in patient care. In 1988, our first syringe hit the market, paving the way for countless medical innovations to come.


To keep up with an increasing demand for our growing portfolio, we opened our first international location, a manufacturing facility in Galway, Ireland. Today, our Galway team continues to thrive. In 2018, they earned the Medtech Company of the Year award in recognition of their dedication.

This same year, we also saw the opening of Merit Sensor, one of several product divisions that bolster our offerings.


This year marked the opening of our Merit Houston facility. A Center of Excellence, Merit Houston specializes in polymer extrusions and catheter manufacturing.


More than a decade of focus and persistence came to fruition in 2000 with the launch of our first compression device, the RADstat® Radial Artery Compression Device. Since then, we’ve continuously innovated and improved our compression device offerings to provide clinicians with superior options—the PreludeSYNC EZ™, PreludeSYNC DISTAL™, and SafeGuard® family of products.


As our US presence continued to grow, we added another location through the acquisition of our Richmond, VA, facility. An integral part of our business, it remains an important manufacturing and distribution center, responsible for producing more than 35 million components each year.


Close to home and far away, this year brought big developments. Our Salt Lake headquarters opened a new manufacturing facility. Doubling its existing square footage, the new facility added more than one hundred new production jobs.

We also opened a facility in Venlo, Netherlands, specializing in manufacturing coated wires, and in 2008, followed with a sister location in Maastricht, our EMEA Distribution Center of Excellence.


In 2010, we opened our Paris facility. This expansion gave us state-of-the-art embolic material manufacturing capabilities. Our global capacity for delivering more minimally invasive treatment options to patients increased.


Our Tijuana, Mexico, facility opened in 2015, where our dedicated employees enjoy award-winning cafeteria service, a safe and convenient transportation system, and more. As one of our primary manufacturing and assembly facilities, our Tijuana team plays a critical role in our success.


In 2016, we launched the SCOUT® Radar Localization system. Designed to improve patient outcomes, SCOUT marked our strong commitment to reducing the burden breast cancer has on patients and their loved ones. As of 2021, SCOUT surpassed 200,000 procedures worldwide.

As the company expanded, we were able to show our appreciation for employees by offering more services that prioritized their health and wellness. This year Merit Salt Lake introduced the Merit Care Clinic, an on-site practice that provides low-cost healthcare to employees and their dependents. We also opened the Merit Employee Garden, a 1-acre parcel of land that offers fresh produce as well as the opportunity for our team to spend time outdoors.


We were proud to welcome Singapore to our Merit family in 2017 as one of our chief centers for innovating and manufacturing. Our Singapore team has more than 30 years of experience in Critical Care product development; and with its R&D laboratory capabilities, it closely collaborates with government agencies and research institutes.


Today, Merit is a billion-dollar company that continues to have a positive impact on patient lives worldwide. Our family of 6,800 employees make this possible by fulfilling the Merit mission to Understand, Innovate, and Deliver.

To our dedicated team, thank you for your efforts in building the next great healthcare company. We look forward to many more years of making a difference.

Think Radial®—Join Us to Explore What’s New in Transradial Access

Think Radial - Transradial Interventional AccessAs medical technology rapidly evolves, it’s vital that physicians have access to training to match the pace. Merit Medical’s Think Radial® education program is renowned for providing advanced, highly specialized training to physicians across the globe in both live and virtual formats.

Hear from our knowledgeable proctors, preview session highlights, and learn about how you can get involved.

Why Think Radial?

Think Radial courses offer hands-on training for proximal and distal radial access for interventionalists in multiple specialties, including cardiology, radiology, neurology, and nephrology. These procedures are one of the medical field’s most exciting innovations—not only for physicians, but as an alternative to femoral access for patients.

Potential advantages of distal radial access may include lessened risk of hematoma while maintaining hand functionality for patients, and for operators, may supply enhanced ergonomics and comfort during the procedure. On average, it also requires less intensive post-procedural care from nurses and support staff.

Dr Sandeep Nathan - Think Radial Faculty - Merit Education“Now more than ever there are so many ways to consume medical information,” says Sandeep Nathan, MD, MSc, FACC, FSCAI, interventional cardiologist at the University of Chicago and Think Radial proctor. “It behooves us to use those resources to evolve in our careers and procedures certainly, but most importantly, to do right by our patients.”

This emphasis on improving care for patients is a major driver of physician education programs like Think Radial. New technology and methods can provide more healthcare options, including less invasive procedures and reduced pain.

Dr Darren Klass - Interventional Radiologist, Think Radial Proctor“Physician education allows us to remain at the forefront of knowledge,” says Darren Klass, MD, PhD, MRCS, FRCR, FRCPC, interventional radiologist at the Vancouver General Hospital and Think Radial proctor. “In many instances, the procedure itself may not fundamentally change; however, new techniques and equipment that make the procedure safer and more effective can improve patient outcomes.”

“A Real Winning Combination”: Prelude IDeal™ and PreludeSYNC DISTAL™ Provide Complete Solution for Distal Radial Access

Distal Radial AccessDistal radial access has emerged as an accessible, optimal solution for physicians seeking to provide the greatest experience for their patients. While femoral and traditional radial access have previously been standard, distal radial offers additional advantages to both patient and operator. To support distal radial artery access, Merit offers a suite of products designed to minimize risk, maximize patient comfort, and provide ease of use for care teams to incorporate.

Ethan C. Korngold, MD, FSCAI - Distal Radial AccessWe spoke with Ethan C. Korngold, MD, FSCAI, interventional cardiologist at Providence St. Vincent Hospital in Portland, OR, to hear his experience choosing two Merit products in particular for his distal radial artery access procedures: the Prelude IDeal Hydrophilic Sheath Introducer and the PreludeSYNC DISTAL, a radial compression device specially created for the distal radial access site.

Why Distal Radial?

Literature shows that radial access provides multiple benefits, including less bleeding complications, decreased procedure cost, and enhanced sheath performance.1

According to Dr. Korngold, patients undergoing distal radial access interventions may experience additional advantages over radial access, including increased mobility post-procedure. “It is much less invasive than traditional radial access—my patients are able to resume normal activities much more quickly,” Dr. Korngold says. “Distal radial access may also lead to less occlusion of the radial artery. I think the important thing is that it preserves the radial artery should future interventions be necessary.”

Mitigating Risk

Prelude IDeal Sheath Introducer - Merit MedicalKinking and compressing are recognized challenges for operators when navigating catheters during radial access procedures.

“It’s very important when performing distal access to have a sheath that’s kink resistant. I really do prefer the kink resistance of the braided Prelude IDeal sheath. I also find it has impressive push forces; it’s a stronger, stiffer sheath that performs better than others I’ve used,” Dr. Korngold explains.

Merit designed the Prelude IDeal specifically to reduce the impact of these risks to patients. Composite braiding technology gives the Prelude IDeal sheath a 13% thinner wall than the leading competitor.2 With proprietary engineering, the sheath is thinner and stronger while achieving 124% increased compression resistance and 23% more kink resistance than the leading competitor.2

Prelude IDeal Compression & Kink Resistance Features

Dr. Korngold shares his firsthand experience with similar products. “I’ve used other non-braided sheaths, both slender and non-slender varieties. I found that even the non-slender varieties are just too prone to kinking. The kink resistance of the Prelude IDeal is excellent; it’s an essential feature for distal radial access.”

Maximizing Patient Comfort

PreludeSYNC DISTAL - Secure, Comfortable and EffectiveDr. Korngold has found that he’s received significantly fewer patient complaints of swelling, discomfort, or hematomas since opting for the PreludeSYNC DISTAL.

Constructed with soft material, the PreludeSYNC DISTAL provides comfortable wear. Its three-strap band configuration allows for an adjustable fit with optional extension if needed especially for larger hands. The PreludeSYNC DISTAL also delivers clear, unobstructed site visibility for focused compression. A built-in Slip-n-Lock™ Cap provides a specialized connection, securing syringes during inflation and deflation, supporting patient safety.

“The PreludeSYNC DISTAL band is really just perfectly designed. Everyone who does distal radial access has experimented with different ways of doing it. No solution is as efficient, convenient, or as comfortable for patients,” Dr. Korngold says.

Ease of Use

Medical devices must be effective, but equally important is ease of use. Dr. Korngold reports that incorporating the Prelude IDeal and PreludeSYNC DISTAL into his practice was seamless.

“It’s very easy to train the care team on how to use them properly,” he says, referring to his experience introducing both products to his staff. “Our nurses on the floor found it very intuitive and easy to manage. Both products fit perfectly into our existing workflows, so I’d say it’s a real winning combination.”

A Complete Solution

Merit is committed to developing tools that improve patient’s lives in partnership with the physicians who provide their care. The Prelude IDeal Hydrophilic Sheath Introducer and PreludeSYNC DISTAL are prime examples of this dedication and have become the go-to tools for distal radial access procedures around the globe.

Prelude IDeal™ Provides Real Solution to Common Radial Access Challenge

Prelude IDeal™ Provides Real Solution to Common Radial Access Challenge

During radial access procedures, many thin-walled sheath introducers on the market pose the risk of kinking or compressing, either near the access site or inside the radial artery, resulting in wires, catheters, and other devices unable to move through. After years of research, the Merit R&D team built the Prelude IDeal™, a hydrophilic sheath introducer designed to specifically resist kinking and compression while also facilitate smooth device movement and exchange, providing a real solution to this common radial access challenge.


To combat both kinking and compression, the Merit R&D team envisioned a sheath with a wall that was thinner and stronger than the products physicians currently used.

To achieve this balance, they developed a composite braiding technology to serve as the inner layer of the Prelude IDeal sheath, giving it a 13% thinner wall than the leading thin-walled sheath competitor.1 Unlike other thin-walled sheaths, the braiding of the Prelude IDeal also gives it structural integrity to increase kinking and compression resistance, making it 124% more resistant to sidewall compression and 23% more kink resistant than the leading competitor.1

13% Thinner Wall
Prelude Ideal has 124% increased compression resistance
23% more resistance


With a thinner wall, the Prelude IDeal maintains the same sheath outer diameter (OD) as the market leader but larger inner diameter (ID). This increased internal capacity enables smooth wire, catheter, and device manipulation and exchange.

Merit's Prelude Sheath maintains the same sheath outer diameter but larger inner diameter, available in 4F, 5F, 6F and 7F


The Prelude IDeal was developed specifically with radial access in mind. Combining a thinner wall with a composite braiding technology enable the Prelude IDeal to maintain structural integrity, protecting the sheath from compression during vessel spasm, a potential side effect of radial artery access.

In addition, the Prelude IDeal’s kink resistance is crucial when implementing the distal radial technique, where the anatomy of the hand can be more tortuous and accessing the vessel at an increased upright angle is necessary. The robust structure of the Prelude IDeal makes it a practical device choice in distal radial procedures.


A typical thin-walled sheath may collapse, for example, when it encounters a narrowing of the vessel, preventing catheters and wires from passing through.

With structural integrity provided by its braided composite structure, the Prelude IDeal withstands the natural bends and curves of the artery and aids in straightening the vessel, allowing catheter manipulation and torque without sheath compression.

Prelude IDeal - Smaller OD but Larger ID


The Prelude IDeal Hydrophilic Sheath Introducer has become the tool of choice for radial and distal radial access procedures around the globe. Its story is much like Merit’s overall goal—to listen to the needs of physicians and innovate ways to improve patient care.

Distal Transradial Access Is Taking Social Media by Storm

Distal Radial Access

Distal transradial access—also known by its hashtags #dTRA, #ldTRA, and #rdTRA—is taking social media by storm. An alternative site for conventional transradial access, distal radial access uses the anatomical snuffbox, a method that’s being widely adopted across several fields.

From experiences and preferred products to the latest research and more, physicians are sharing their knowledge through strings of tweets, retweets, and likes—a virtual Twitter buzz signaling that distal transradial is gaining traction both online and off.

Interventional cardiologists can be seen posting their positive procedural experiences and using cutting-edge distal devices.
