Zeon Medical Inc. launched operations on January 1, 1990 as an affiliated company of Zeon Corporation, a polymer chemistry manufacturer. Zeon Corporation has continued to develop medical devices utilizing innovative materials, particularly biomaterials, produced by combining the company's exclusive technologies. The ventricular artificial heart, a typical medical device resulting from these efforts, was the first such product in the world to obtain approval for manufacture from the former Ministry of Health and Welfare (currently the Ministry of Health, Labor and Welfare) in January 1990.
Zeon Medical Inc. began operations in January of the same year to sell these products. In July 1996, the export, research and development, and manufacturing operations of Zeon Corporation were transferred to Zeon Medical Inc., and Zeon Medical Inc. completed the establishment of an integrated system as a highly respected and integrated medical device manufacturer. Since then, the Company has been committed to expanding this field of business.
