Medical Device Components

In recent years, the medical field has seen a growing trend toward minimally invasive and non-invasive surgeries and treatments that reduce physical  burden on patients and minimize surgical wounds. Medical devices used in these procedures –such as catheter-based therapeutic devices and implantable medical devices (hereinafter referred to as “medical  devices”) – require precise approach to affected areas and low reactivity with biological tissues. In addition, accurate visualization under X-ray imaging is a critical factor for identifying the precise positioning of medical devices within the body. Precious metals such as gold (Au) and platinum (Pt) have relatively high density and excellent radiopacity, as well as strong resistance to oxidation and corrosion. As a result, their use as materials f or medical device components has expanded in recent years. As a leading company in the precious metals industry, TANAKA is committed to contributing to the well-being of people worldwide through the development and supply of high-quality precious metal materials with outstanding properties for medical applications.

Leveraging decades of expertise in material development, TANAKA offers the Visi Fine^® series –a group of highly reliable precious metal materials that maximize the properties through proprietary technologies.  These include multiple melting technologies, ultra-fine wire processing, and advanced laser processing. 
The name Visi Fine^® is a coined term combining “Visi” meaning “visibility”, and “Fine” representing ultra-fine and highly refined materials. It reflects our commitment to transforming highly radiopaque precious metals into reliable materials for medical device components through advanced processing technologies.
