Teijin Med-Material Solutions（TMMS）

Our spinning technology, rooted in the Teijin Group's fiber business, infinitely expands the potential of medical-grade fibers. We accommodate diverse materials, from thermoplastic to bioabsorbable and even bio-based materials, custom-designing the required texture and function by controlling fiber thickness, morphology, and cross-sectional shape. These high-performance fibers are provided in compliance with medical material regulations.

TMMS possesses the technology to safely and efficiently handle natural and bio-based materials. We use raw materials such as gelatin and collagen, and apply proprietary processing technologies to provide medical materials of stable quality. These materials exhibit excellent biocompatibility and offer significant potential in the fields of regenerative medicine and tissue engineering.

TMMS employs diverse fiber processing technologies, including woven, warp-knitted, weft-knitted, braided, and non-woven fabrics. By combining these technologies with our fiber properties, we can freely design and realize the complex structures and functionalities required for medical devices.

• ■ Weft knitting

  

• ■ Braiding

  

• ■ Non-woven fabric

  

TMMS's composite technology imparts high functionality unattainable with single materials by combining multiple components.
We offer a high-strength, bio-degradable and absorbable material with bioactivity, composed of a composite of poly-L-lactic acid (PLLA) and uncalcined hydroxyapatite (u-HA).
This composite is available in rod sizes of φ6.5mm, φ7.0mm, and φ8.0mm, with an u-HA/PLLA ratio of 30/70 (wt%).

TMMS also develops gel materials with excellent biocompatibility. They are applicable to various medical uses, including drug delivery systems (DDS), tissue engineering, and regenerative medicine scaffolds. Based on the technology we have cultivated, we provide design, contract development, and manufacturing tailored to customer specifications.
