At Merit Medical, we’re dedicated to using the most advanced materials, designs, and manufacturing techniques with the goal of delivering solutions you can always depend on. Our PreludeEASE™ Hydrophilic Sheath Introducer is a perfect example of this commitment. Designed for strength, data shows the PreludeEASE resists compression better than the leading competitor—making it the New Go-To sheath.1
Compression resistance is an essential factor when considering a new sheath. Case studies have shown that if an arterial spasm occurs during a procedure, it can lead to the sheath compressing into the catheter, entrapping it within the vessel, and making removal of the catheter from the sheath difficult.2
Some thin-walled sheaths can be prone to compression and kinking that could result in difficult catheter manipulation. In the event of radial spasm, the catheter and sheath may need to be removed. Using a product with robust sheath tubing, like the PreludeEASE, may help clinicians avoid this problem. When tested against the leading competitor, the PreludeEASE displayed excellent compression-resistance performance.1
Other PreludeEASE advanced features include a large inner diameter for easier transitions and increased device compatibility and hydrophilic coating to facilitate insertion and removal as well as patient comfort.3 Moving smoothly from wire to dilator and dilator to sheath, the PreludeEASE streamlined design requires up to 30% less insertion force in comparison to the leading competitor.1
To accommodate varying patient anatomy, the PreludeEASE is available in multiple size configurations that range from 4F-7F diameters and can be customized in kits and packs to include other tools you need to achieve radial success.
Explore the New Go-To PreludeEASE and all it has to offer by visiting the PreludeEASE product page or talk to a knowledgeable Merit representative today.

Merit Medical is committed to the radial approach, with a comprehensive portfolio of radial products supporting radial procedures from set-up and access through hemostasis, as well as the ThinkRadial training program for Interventional Cardiologists and Radiologists. And in this year, the 25th anniversary of radial access, we are happy to spotlight some of our key radial products, starting with the sheath used to gain access to the radial artery.
The has evolved to address the needs of radial interventionalists. The smooth transitions between wire to dilator, and dilator to sheath, have been fine tuned for patient comfort, resulting in up to 30% less insertion force, as compared to the leading competitor1. The hydrophilic coating further facilitates insertion and removal as well as patient comfort.2
Studies also show that the hydrophilic coating on sheath introducers can reduce the incidence of artery spasm and improve patient comfort during transradial diagnostic and interventional coronary procedures.3
The PreludeEASE™ maintains a robust design that resists kinking while still providing a large inner diameter for increased device compatibility. Combining a slim profile and a large inner diameter, the PreludeEASE provides optimal dimensions without compromising integrity or performance.
On May 31, 2017, Dr. Ferdinand Kiemeneij, “@ferdikiem”, tweeted about the PreludeEASE:

Merit Medical will be hosting the next ThinkRadial Education Course on October 13-14 for Interventional Cardiologists and Radiologists. Physicians are already looking forward to this course and the opportunity to learn from the “Father of Transradial Intervention,” Dr. Ferdinand Kiemeneij. Merit is honored to once again have Dr. Kiemeneij proctor this course, to share his extensive knowledge and experience, as he did in the April ThinkRadial Course. This course will be held at the Merit Medical Global headquarters in Salt Lake City, UT on Friday, October 13 and Saturday, October 14, 2017.
Interventional Cardiologists who currently practice the transradial access technique, who want to advance their skills for more complex interventional procedures, will be proctored by Dr. Sandeep Nathan (University of Chicago) as well as Dr. Ferdinand Kiemeneij. Interventional Cardiologists attending the course will present their own complex cases for discussion and troubleshooting as well as observe complex taped cases. These physicians will learn how to navigate potential complications and increase their use of transradial for complex interventions.
Interventional Radiologists who are new to the radial approach as well as those who want to increase their knowledge and skill will be proctored by Dr. Darren Klass (Vancouver General and UBC Hospitals). Interventional Radiologists will be taught the data and economics supporting transradial access, learn about patient selection, room set-up, and equipment selection. They will learn and practice access and hemostasis techniques and discuss how to navigate potential complications. Both groups will have the opportunity to practice the radial technique on cadavers.
Dr. Kiemeneij performed the first transradial coronary angioplasty in 1992, followed by transradial stenting in the same year and stenting on an outpatient basis in 1994.
Dr. Klass is an expert in transradial radioembolization and is developing a robust hardware platform for radial access to the liver. His practice is 90% radial for liver interventions and fibroid embolization.
Dr. Nathan describes his mindset as “radial first” and utilizes the transradial approach in more than 75% of his coronary cases. He believes that transradial “is a golden opportunity to improve patient comfort and safety, without compromising procedural efficacy.”
The October ThinkRadial Course is a full day and a half of didactic presentations, taped cases and hands-on training opportunities, complimented by a group dinner and presentation by the guest of honor, Dr. Ferdinand Kiemeneij.

In order to keep up with the growth and progress of interventional medicine, Merit Medical is hosting a dynamic ThinkRadial™ training course on April 21-22 at Merit Medical headquarters in Salt Lake City, Utah. For the first time in the US, world-renowned Interventional Cardiologist Ferdinand Kiemeneij, MD, PhD, will be attending as the special guest of honor, co-proctoring the interventional radiologist and brand new advanced interventional cardiologist courses, lecturing at both training sessions.
Recognized as the “Father of Transradial Intervention,” Dr. Kiemeneij first began applying transradial access to angioplasty and stent placement procedures as early as 1992. This led to stenting on an outpatient basis in 1994. Since then, Dr. Kiemeneij has been lecturing and teaching physicians the transradial technique, as well as its many advantages over transfemoral access. More than two decades later, the European Society of Cardiology (ESC) gave the transradial approach the highest degree of recommendation over transfemoral access for coronary angiography and Percutaneous Coronary Intervention (PCI) in patients with Acute Coronary Syndromes (ACS).1
Sought after worldwide, Dr. Kiemeneij was invited in 2013 to build an intervention program at the Tergooi Hospital in The Netherlands. The author of numerous clinical articles and a 2016 book entitled, Transradial Coronary Interzentions, Dr. Kiemeneij has built his practice by combining writing, proctoring, lecturing, and training fellow physicians the world over.
Dr. Kiemeneij will co-proctor advanced interventional cardiologist attendees with venerated Interventional Cardiologist Sandeep Nathan, MD, MSc, FACC, FSCAI, of the University of Chicago Medical Center in Chicago, Ill. He will co-proctoring the interventional radiologist portion with esteemed Darren Klass, MD, PhD, MRCS, FRCR, FRCPC, Interventional Radiologist at Vancouver General and UBC Hospitals in Vancouver, Canada. Dr. Kiemeneij will also share his knowledge and expertise during the groups’ hands-on trainings. Following the Friday sessions, Dr. Kiemeneij will give an invaluable presentation at a special group dinner event.
Space for this program is limited. To submit your interest in this upcoming Think Radial training course and learn from the “Father of Transradial Intervention,” talk to your Merit Representative or visit Merit.com/Education.

For well over a decade, transradial access has been used for coronary interventions. In comparison to the transfemoral approach, research has linked transradial with increased patient preference and fewer vascular complications.1,2 A more cost-effective approach that has success rates similar to the transfemoral technique, transradial access is expanding into other fields of medicine.3,4
Once reserved as an alternative mode of arterial access, the interventional radiology community is now debating whether radial artery access could provide higher patient care value under the “best practices” concept.5 With the growing number of physicians choosing transradial for interventional coronary and radiology procedures, Merit Medical has developed #NextGenRadial—the only second generation of radial products on the market. Combined with their innovative hands-on ThinkRadial™ training courses, Merit provides the skills and tools physicians need to launch new radial practices or successfully bring existing practices to the next level.
The femoral artery has been the traditional access point for the majority of interventional procedures, but a recent notable shift has taken place. Just last year, the European Society of Cardiology (ESC) gave the radial approach the highest degree of recommendation over femoral access for coronary angiography and Percutaneous Coronary Intervention (PCI) in patients with Acute Coronary Syndromes (ACS).6
“New data shows that the radial approach is superior to the femoral not only in terms of vascular complications and major bleeding events but also in reducing all-cause mortality,” said Professor Marco Roffi (Switzerland), Task Force Chairperson in an ESC press release. “It is recommended that centers treating ACS patients implement a transition from transfemoral to transradial access.”6
To demonstrate its superiority, multiple studies have emerged. The well-known MATRIX Study, a 2015 randomized multicenter trial by Valgimigli et al. compared radial with femoral access in patients with ACS with or without ST-segment elevation myocardial infarction and who were about to undergo coronary angiography and PCI.7 Consisting of 8,404 patients, results showed fewer adverse events among those who underwent the transradial approach (9.8% or 410) in comparison to those who underwent transfemoral (11.7% or 486).
Given these results, the authors of the study concluded that “radial as compared to femoral access reduces net adverse clinical events, through a reduction in major bleeding and all-cause mortality” and that transradial access should be the “default approach in patients with an acute coronary syndrome undergoing invasive management.”7 Other randomized investigations provide data that show transradial access to be associated with shorter hospital stay.8 The 2011 multicenter RIVAL trial showed transradial access to be patient-preferred, with 90% of those who underwent the transradial approach designating it as their access site of choice if they needed another procedure.1
Patients undergoing transradial non-coronary interventions are also seeing benefits. A 2015 feasibility study by Posham et al. reported that transradial access was well tolerated among patients receiving a range of peripheral vascular interventions, including chemoembolization, visceral intervention, and uterine artery embolization.9 In this single-center review, 936 patients were evaluated for 1,512 transradial noncoronary procedures between April 2012 and July 2015. Results published in the Journal of Vascular and Interventional Radiology showed transradial access to have a technical success rate of 98.2%. Major complications and minor complications were minimal at 0.13% and 2.38% respectively. A total of 27 cases (1.8%) required crossover to transfemoral access.
Taking patient and clinician safety a step further, a superiority study by Khayrutdinov et al. showed that utilizing the radial technique for UFE and PAE led to reduced procedural time, thereby minimizing radiation exposure.10
From a cost benefit standpoint, the transradial approach can save money. In 2013, Amin et al. published results of a multicenter study that evaluated costs of transradial and transfemoral PCI from a contemporary hospital perspective.3 Over 7,000 procedures were performed between January 2010 and March 2011. Of these, 17% of patients underwent the transradial approach. In comparison to transfemoral, transradial was associated with shorter hospital stays (2.5 vs. 3.0 days) and fewer bleeding events (1.1% vs. 2.4%). Total cost savings for transradial access was $830 per patient, of which $130 were procedural savings and $705 were post procedural savings. Even greater savings were seen in high-risk patients.3
Despite these findings, only 20% of interventional procedures in the US are performed via transradial access.11 Low adoption of the transradial approach may be related to challenges learning the technique. And yet, data taken from the CathPCI Registry demonstrate that operator proficiency improves with greater transradial experience. Despite the learning curve of about 30 to 50 cases, patient safety is still maintained with high procedural success and low rates of mortality, bleeding, and vascular complications.12
As awareness of the radial technique increases among patients and physicians, Merit has developed the renowned ThinkRadial training program in an effort to provide comprehensive exposure to the next generation of transradial operators. Getting its start in 2014, ThinkRadial invited the best and brightest to spearhead the course. Leading the Interventional Cardiology Courses is Sandeep Nathan, MD, MSc, FACC, FSCAI, an Associate Professor of Medicine and Medical Director of the Cardiac Intensive Care Unit at the University of Chicago Medical Center, where he also serves as the Co-Director of the Cardiac Catheterization Laboratory and Director of the Interventional Cardiology Fellowship Program.
In 2015, Merit extended its cutting-edge ThinkRadial course to interventional radiologists by bringing on Interventional Radiology ThinkRadial Course Director Darren Klass, MD, PhD, MRCS, FRCR, FRCPC, an Interventional Radiologist at Vancouver General and UBC Hospitals, and head of the MRI Division for Vancouver Acute in Vancouver, Canada. Well-known across borders, Dr. Klass performed the first transradial radioembolization and chemoembolization of the liver in Canada.
Throughout the program, ThinkRadial attendees are split into cardiology and radiology specific tracks, but also have several opportunities to learn from each other as a combined group. In their specific tracks, they participate in didactic presentations and discuss taped cases that cover a range of topics, including patient selection, access technique, and potential complications. What’s more, hands-on training with cadavers and simulation training models provide physicians at every level of experience with radial solutions needed for their own practice.
“After attending the ThinkRadial course, I had all the tools I needed to begin transitioning my practice to radial,” said Shivank Bhatia, MD, Interventional Radiologist at the University of Miami Health System, and ThinkRadial Alumni, January 2016. “My first case post ThinkRadial was supported by Merit Medical; their reps did a great job with in-service for the entire support staff, making the introduction of radial products seamless. Using a radial approach has led to great patient experiences, reduced procedure time and overall improved patient satisfaction. I intend to be “radial first” within the next six months to one year.”13
Crossing continental lines, ThinkRadial courses are offered in Europe, South Africa, South America, and Asia—in addition to the US courses offered both at Merit Medical’s Utah headquarters and regionally.
The Course Directors emphasize providing a full radial “education,” as opposed to just a training, so that attendees have the knowledge they need to personalize the experience once they head back to their practice. “The class provided me with a template approach but the foresight to adapt the training to my practice as I saw fit,” explained Mohammad A. Bilal, MD, DABR, Director of Vascular and Interventional Radiology at John T Mather Memorial Hospital, Port Jefferson in Long Island, NY, and ThinkRadial Alumni, April 2016. “I was most excited to leave with the proper set of tools to implement the approach.”13
To fully equip this next generation of experts, Merit provides one-of-a-kind #NextGenRadial products to facilitate each step of transradial access.
The reusable Rad Board fits all cath lab and radiology procedure tables and is reversible for right- or left-side access—making it an economical choice. Putting safety first, a section of Xenolite TB is embedded in the Rad Boards and has shown to help reduce radiation scatter exposure levels by up to 44% at waist height and up to 25% at neck height, according to an independent survey.* Convenient uprights on the sides form a reservoir with the drape to keep devices and fluids on the board. Cutout handles allow for convenient moving and transport.
Each Rad Board accessory—Rad Board Xtra™, Rad Trac™ and Rad Rest®—provide additional support for radial access procedures. The Rad Board Xtra allows for 90° perpendicular extension of the arm during access, while the Rad Trac encourages easy placement of the Rad Board when the patient is on the table. The soft Rad Rest arm cushion boosts patient comfort by providing ergonomic wrist and elbow support during radial access procedures.
PreludeEASE is Merit’s newest line of Hydrophilic Sheath Introducers. Studies show that hydrophilic coating on sheath introducers can reduce the incidence of artery spasm and improve patient comfort during transradial diagnostic and interventional coronary procedures.14
PreludeEASE kink-resistant tubing helps to provide procedural reliability. Smooth transitions between wire to dilator and dilator to sheath were designed for ease of insertion and can help enhance patient comfort. Available in 4F through 7F diameters and multiple lengths, PreludeEASE anticipates various clinical needs and diverse patient anatomy without compromising its slim profile and large inner diameter.
Diagnostics: Performa® Diagnostic Cardiology Catheters
Merit’s Performa diagnostic cardiology catheter is designed with improved shaft strength for better pushability and torque. Made from Nylon Pebax® material selected to give the Performa improved kink resistance, its flat-wire braid design offers greater stability and increased torque. A large inner lumen enables increased flow rates. The Performa’s winged polycarbonate hub offers enhanced handling and control and the radiopaque tip allows shaft visualization under fluoroscopy to ensure accurate placement. Anticipating individual patient needs, Merit’s diagnostic catheters come in radial specific shapes and lengths. Also available is the Performa Multipack, which combines all three typical workhorse catheters in one convenient package.
Hemostasis: Safeguard Radial™ Compression Device
The Safeguard Radial Compression Device is a 26-cm long self-adhesive wristband designed to assist with hemostasis following radial access procedures. The band allows for adjustable compression of the radial puncture site with an inflatable bulb and standard Luer valve for easy inflation and deflation with any standard Luer syringe.
A clear window allows for better visualization of the puncture site and the size and shape of the bulb minimizes compression of surrounding nerve structures or other areas. The one-size-fits all cloth wristband offers greater patient comfort and fits securely around the wrist.
Through evidence-based data, education, and products, Merit Medical’s #NextGenRadial toolkit provides physicians with the skills, products—and above all—the confidence they need to take full advantage of the radial approach. A technique where the data speaks for itself, radial access is no longer the future of medicine—but the present. Will you be part of the Next Generation?
