Medical Device Materials

Contributing to a healthy and prosperous society ～Well-being～

In recent years, minimally invasive and non-invasive surgeries and treatments have become a trend in medical settings, aimed at reducing the burden on patients' bodies and minimizing wounds. Catheter treatment devices and medical implants (hereinafter referred to as treatment devices) used in these surgeries and treatments require precise approaches to the affected area and low reactivity with internal body tissues. Furthermore, visibility under X-ray irradiation is an important factor for accurately determining the position of treatment devices within the body. Precious metals such as gold (Au) and platinum (Pt) have relatively high specific gravities, high X-ray opacity, and are resistant to oxidation and corrosion, making them increasingly used as materials for treatment device components. As a leading company in the precious metals industry, TANAKA will continue to strive to contribute to the well-being of people around the world by developing and providing high-quality precious metal materials with excellent characteristics for medical use.

High-Quality, Highly Reliable Components for Medical Devices—Visi Fine® Series

TANAKA utilizes its long-standing expertise in material development to offer a series of highly reliable materials that maximize the properties of precious metals under the brand name Visi Fine®, using unique technologies such as various melting technologies, ultra-fine wire processing, and laser processing.
Visi Fine® is a coined term that combines "Visi" (visible) and "Fine" (fine and sophisticated materials). It embodies TANAKA's commitment to using advanced processing technologies to create materials with excellent X-ray impermeability that are highly reliable for use in medical device components.

Advanced material processing technology and a stable global supply system as a leading manufacturer in the precious metals industry

TANAKA has a history of 140 years as a precious metal manufacturer and has advanced materials processing capabilities backed by rich expertise in precious metal development and technical know-how. We provide one-stop services for all aspects of precious metals, from "bullion procurement" to processing, manufacturing, sales, and "recycling."
In order to respond quickly not only in Japan but also overseas, we have established a global network and can ensure a stable supply of precious metal materials as the largest precious metal manufacturer in Asia. Precious metal materials are provided under a reliable production system managed in accordance with the ISO13485 system.
TANAKA contributes to the technological advancement of the medical and healthcare industries through the stable supply of precious metal materials.
