The history of our company started as JUNKEN CO., LTD. which developed a domestic artificial heart lung apparatus in 1967. Since then, we have developed and manufactured medical equipments which support the medical treatment of the circulatory organ field.

We currently offer the original brand which adopted highly advanced technologies such as the only device for continuous blood purification "AcuFil series" with volume measurement system and the polyester vascular prostheses "J Graft series", and "J Graft OPEN STENT GRAFT" which are the only products manufactured domestically. In addition to these projects we have started preparing to enter into the new field of “gastrointestinal stent”.

As of January 1, 2017 we will merge with Japan Lifeline Co., Ltd., our parent company. As a member of Japan Lifeline Co. Ltd., we will continue after the merger, too, to develop a new medical field and to research for characteristic products and materials. We will also make an effort to supply high quality Japanese medical equipments to patients both inside and outside Japan.
