Darren Klass, MD, PhD - Interventional Radiologist, Vancouver, Canada
Advancing new vascular access and delivery pathways for embolotherapy.
"The advances we're making, and their impact on patient care, inspire me to push forward."

Never one to accept the status quo, Dr. Klass is always looking for new ways to advance embolotherapy.

Whether he's helping design embolics to better treat liver cancer, or improving transradial access to reduce complications and recovery time, Dr. Klass' leadership is driving rapid improvement in patient care.

"Seeing my patient up on his feet an hour after the procedure and cancer-free three years later is my motivation."

Merit Medical is proud to support the work of visionary interventional radiologists like Dr. Klass.

Dr. Klass is an interventional radiologist at Vancouver Imaging, working at Vancouver General and UBC Hospitals in Vancouver, Canada.

He obtained his medical degree from the University of Pretoria in South Africa and then trained initially as a surgeon and then as a radiologist at the Norfolk and Norwich University Hospital in Norwich, England, before completing a fellowship in interventional radiology at the University of British Columbia in Vancouver, Canada.

Dr. Klass is a Member of the Royal College of Surgeons of England, a Fellow of the Royal College of Radiologists in England and a Fellow of the Royal College of Physicians and Surgeons in Canada.

He has an interest in thermal ablation techniques and clinical outcomes thereof. He has specialist training in MR angiography and venography, with particular reference to low dose contrast enhanced MR angiography.

Dr. Klass has performed over 200 radial interventions including liver, renal and splenic interventions, uterine artery embolization and embolization procedures throughout the abdomen and pelvis for acute hemorrhage. His current practice is approximately 90% radial access.

Dr Amman Bolia MBChB, DMRD FRCR - Interventional Radiologist, Leicester, United Kingdom
Advancing peripheral intervention for the treatment of vascular disease.

Dr. Amman Bolia is a pioneer in Interventional Radiology specializing in peripheral vascular disease. In 1987 he developed a technique to treat critical limb ischemia called Subintimal Angioplasty. His technique doesn’t require many materials or the use of very expensive medical devices, is relatively simple to execute and works well. Yet for the first ten years Dr. Bolia found it difficult to convince his peers to transition to this new technique. Convinced that this technique could efficiently and without undue costs alleviate the pain that these patients suffer from, Dr. Bolia pushed on. Today, the Subintimal Angioplasty technique has stood the test of time and is considered one of the most useful, efficient and cost effective methods for the treatment of critical limb ischemia.

"I believe in medicine that works simply and efficiently and is readily available to both the practitioner and the patient. And I'm driven to find medical techniques and devices that make this possible."
Dr. Bolia currently serves as a Consultant Radiologist for the University Hospitals of Leicester NHS Trust in Leicester, United Kingdom. He has been nominated for the prestigious Pioneers in Performance Award by the Cardiovascular and Interventional Radiological Society of Europe.

Dr. Bolia is currently working with Merit Medical on ideas to continue to advance peripheral intervention.


Christoph Binkert, MD, MBA - Interventional Radiologist, Winterthur, Switzerland
Advancing new radial pathways for embolic therapies in interventional radiology
"Every day, I see the differences we can make for our patients. A transradial approach can get patients back on their feet almost immediately, and may reduce complication rates as well."

Since completing his fellowship over 15 years ago, Dr. Binkert has grown more and more passionate about the role of interventional radiology in changing patient care. In his practice, Dr. Binkert performs a wide spectrum of procedures, and enjoys the opportunity he has to treat patients and oversee their follow-up care.

Among the spectrum of procedures he performs, Dr. Binkert is especially interested in the capabilities of embolization therapy. From treating liver cancer with radioembolization, chemoembolization, or bland embolization to reducing uterine fibroids with UFE, Dr. Binkert brings a consultative approach, establishing a relationship with the patient and the entire medical care team.

Dr. Binkert has also been a significant figure at the forefront of the movement to advance the radial approach. Noting improved haemostasis and faster recovery time, he has worked diligently to perfect the technique and educate the community about its advantages.

Prof. Dr. Med. Christoph A. Binkert is the Director of Department of Radiology and Nuclear Medicine (Direktor Institut für Radiologie und Nuklearmedizin) at Kantonsspital Winterthur, Winterthur, Switzerland. He is the Chief Physician of Radiology (Chefarzt Radiologie). Dr. Binkert serves as the CIRSE Scientific Programme Committee Deputy Chairperson.

Francisco Carnevale, MD, PhD - Interventional Radiologist, São Paulo, Brazil
Advancing the treatment of BPH with embolotherapy
"Knowing how much the new technique my team and I developed helps BPH patients is incredibly fulfilling. Sharing it with other physicians, and continuing to improve the quality of life for so many patients, drives my commitment to innovation."

Dr. Carnevale is known as a passionate and ingenious leader in the field of interventional radiology. He and his team recently developed a successful method to treat patients with symptomatic Benign Prostatic Hyperplasia (BPH), called the PErFecTED (Proximal Embolization First, Then Embolize Distal) technique. In this novel technique, embolization of the prostatic arteries begins from a proximal position to allow good distribution of the embolic, then it is followed by distal investigation and embolization to achieve complete occlusion of the prostatic parenchyma.

This innovative method continues to show excellent clinical results in reducing prostate size, relieving lower urinary tract symptoms, and improving quality of life. With its success, physicians have a new alternative for helping BPH patients avoid the adverse events that can result from more invasive procedures, including retrograde ejaculation and incontinence. (Francisco C.Carnevale, 2013)

Dr. Carnevale continues to investigate and refine his PErFecTED technique, while serving as mentor to other physicians and presenting the technique at congresses and training sessions. An Associate Professor of Medicine at the University of São Paulo, Brazil, he is Director of the Interventional Radiology Fellowship Program, and coordinates the Interventional Radiology post-graduate course.

Embolics used in the PErFecTed™ technique are not approved in the United States for the treatment of patients with symptomatic Benign Prostatic Hyperplasia.  The safety and effectiveness of the embolics for use in this indication have not been established and are limited by federal U.S. law to investigational use only.
