As a medical device manufacturer


Developing and manufacturing excellent in-house products the medical field really needs

Developing in-house products that reflect the needs of the medical professionals



In response to the diverse needs of the clinical practice in Japan, Japan Lifeline established The Research Center as a R&D base in 1999 and started developing medical devices. In 2000, we opened Ukima Factory and launched guide wires as our first in-house products in 2001. Stepping up its pace as a manufacturer, the company has since enhanced its manufacturing capabilities and expanded its in-house product portfolio including the EP and ablation catheters.

In 2012, Japan Lifeline brought its first one-of-a-kind in-house product, the Internal Atrial Cardioversion System, to the market. This system was first developed to meet the potential needs of the clinical practice in the field, and the system has become highly valued and are now widely used throughout Japan. Ichihara Factory has also developed the Open Stent Graft, the first product of its kind in Japan, which was brought to the market in July, 2014.

As a Japanese company, our advantage is that we maintain close ties with the medical community that can be directly utilized for product development and that we can harness for the development of our own innovative products.

Pursuit of high level of quality for medical devices



Our factories set a rigorous quality control standard for our medical devices to avoid any defects. Because manufacturing of our catheter products requires complex and delicate processes, we have highly experienced and competent staff with skills to do fine, detailed work that lead to the highest quality.

As part of our effort to ensure a stable supply of our ever expanding product portfolio in the medium and long term, Oyama Factory in Tochigi prefecture began its full time operations in October, 2014. The Oyama Factory is responsible for the final processes such as inspection, packaging and sterilization of products manufactured at subcontracting factories both in Japan and overseas. The Oyama Factory enabled us to establish a framework that can deal with increased manufacturing volume in the future while maintaining our high quality standards.

Moveing one step ahead in the development of production systems as a group



Ichihara Factory develops and manufactures vascular grafts and Open Stent Grafts that Japan Lifeline is marketing, and they have the highest performance and quality as the only products manufactured in Japan.

We launched a self-developed balloon catheter in April, 2014, which we manufacture by transferring the technology to our subsidiary, JLL Shenzhen Co., Ltd. (Shenzhen, Guangdong Province, China). In addition, we are taking measures to strengthen the production system as exemplified by the Malaysia factory of JLL Malaysia Sdn. Bhd. (Penang province, Malaysia). It was our first factory that we established from scratch and it has started operation since June 2020.

With our Medical Technology Park as our core R&D and manufacturing hub, which also has the Toda Factory as the manufacturing function, we will enhance coordination with our subsidiaries and maximize the synergy as a group to improve and expand our self-manufactured product portfolio.
