Our Culture

Charting the uncharted territories of vascular disease doesn’t happen overnight. It takes passion, grit, and heart to never stop seeking solutions. The kind of determination that has fueled Infraredx for nearly 30 years.


Our Leadership

Nozomu “Fuji” Fujita

President and CEO, Infraredx, a Nipro Company General Manager, Nipro Vascular Business Division

Having been employed at Nipro for nearly 25 years, Nozomu Fujita takes the Nipro creed of “Willingness” to heart. He joined the company immediately after earning his master’s degree in engineering from the Department of Applied Chemistry at the esteemed Osaka Institute of Technology, and his career grew as Nipro continued to expand.

Steve Sum, PhD

Sr. Vice President of Technology Innovation and Regulatory

Steve Sum is an academic at heart. After earning a BSc in Chemistry & Mathematics at the University of Waterloo in Ontario, Canada, he went straight on to earn a MSc in Information & Systems Science from Carleton University, and then a PhD in Chemometrics and Analytical Chemistry from the University of Delaware.

David Barone

Vice President of Product Development

If not for his love of music, David Barone might never have joined Infraredx. When then-Director of Catheter R&D, Jerry Brightbill, asked him to play drums with his band for the Infraredx holiday party in 2005, David found himself at founder Jim Muller’s home, surrounded by the entire company. Brightbill, who plays guitar had joined Infraredx a few years earlier and, during jam sessions, would often ask David to check them out.

Results of the PROSPECT II Natural History Study Demonstrate High-Risk Plaques Identified by NIRS+IVUS Imaging are Linked to Future Coronary Events

Infraredx, a Nipro Company, a pioneer in intravascular imaging for mapping coronary artery disease, announced positive results from the PROSPECT II and PROSPECT ABSORB studies, presented today as a late-breaking clinical trial at TCT Connect, the 32nd annual scientific symposium of the Cardiovascular Research Foundation. The PROSPECT II study demonstrated the ability of near-infrared spectroscopy (NIRS) imaging plus intravascular ultrasound (IVUS) to identify coronary plaques responsible for future coronary events. The randomized substudy PROSPECT ABSORB, which was simultaneously published in the Journal of the American College of Cardiology (JACC), showed treatment of high-risk vulnerable plaques with a bioresorbable vascular scaffold (BVS) was safe and substantially associated with favorable long-term clinical outcomes compared to guideline-directed medical therapy (GDMT) alone.
