Toray Wins 53rd JCIA Technology Award for Developing and Commercializing Antithrombogenic Artificial Kidney

Tokyo, Japan, May 24, 2021 – Toray Industries, Inc., received the 53rd JCIA Technology Award from the Japan Chemical Industry Association on May 21 for developing and commercializing an anti-thrombogenic artificial kidney. This is the sixth time for the company to win that award, the previous occasion being in 2016. Toray drew on its core nanotechnology and computational chemistry capabilities to create this artificial kidney, a polysulfone membrane, in response to a growing need to enhance anti-thrombogenic performance in line with dialysis treatment advances. The company developed the artificial kidney to efficiently treat chronic and acute renal failure, thereby improving patients’ quality of life while reducing medical professional workloads. Toray looks to develop high value-added medical supplies that materialize its corporate philosophy of contributing to social progress by delivering new value while attaining sustainable growth.

Key technology features
Artificial kidneys remove waste products from the blood of renal patients. These dialyzers incorporate mainstream polysulfone material blended with hydrophilic polyvinylpyrrolidone to provide anti-thrombogenic performance. This is good but could be better. Toray applied a proprietary hypothesis focusing on how adsorbed water interacts with polymers, using computational chemistry in the polymer design process. The company thereby found that a new anti-thrombogenic polymer can better suppress platelet adhesion than polyvinylpyrrolidone.

Applications
The company has employed its award-winning technology in offerings that have earned accolades for its contributions to quality of life and clinical efficiency in enhancing anti-thrombogenic performance. One is Toraylight NV, a hemodialyzer for chronic renal failure. Others are ToraylightHDF and Toraysulfone® NV hemodialysis filters and HEMOFEEL SNV, which provides continuous and gentle hemofiltration for acute renal failure.
