TamaBio : Contributing to medical care through innovative technology
TamaBio was established in April 2016 using RIKEN, the National Research and Development Agency’s special processing technology for polymer resin as a practical basic technology. TamaBio has so far obtained manufacturing and sales approval (Class IV : Highly Controlled Medical Device) from the Ministry of Health, Labor and Welfare for the Dura Mater Substitute “DuraBeam®” and the Pericardial Membrane “PeriBeam®”, and has obtained core patents in Japan, The United States, The People’s Republic of China, and Taiwan. The products are distributed by major specialized medical device companies to medical institutions and hospitals. Tamabio's synthetic artificial biomembrane has been used clinically in thousands of surgeries to date and is expanding.
The essence of TamaBio's artificial biotechnology is to realize the development of medical devices that promote the regeneration of human organ tissues and cells. TamaBio's products have been shown to be highly biocompatible and to bring about biological tissue repair through thousands of clinical use results to date. TamaBio has obtained patents for nerve damage repair sheets, brain damage repair sheets, and spinal cord injury repair sheets in collaboration with Tohoku University (the patent was registered in 2024). TamaBio will continue to forge ahead with the development of medical devices that can repair and regenerate patients' lost tissue.

TamaBio is promoting the development of Dura Mater Substitute “DuraBeam®︎”, Pericardial Membrane “PeriBeam®︎”, and artificial organs and regenerative medicine technologies in more critical and promising fields. Medical devices such as implants are being developed around the world as functional substitutes for patients’ lost organs, but in clinical settings, various adverse events such as postoperative infections, adhesion with self-tissue, calcification due to long-term use and leakage / blockage of bodily fluids are issues. TamaBio products are highly biocompatible, and overcome these issues through its processing technology, and in recent years have been used as permanent implantation devices or short-term use devices in many surgeries.
The important thing about TamaBio's technology is that it regenerates tissues in the human body, that is, it regenerates important cells and tissues as a whole to maintain their health and restore organ function. It is a technology to produce highly biocompatible polymer compounds, and to process biomembranes to give them the ability to regenerate damaged tissue after implantation.
In addition to the latest developments in nerve injury repair sheets, brain injury repair sheets, and spinal cord injury repair sheets, important research results are being produced daily in the field of cardiovascular surgery and other fields. We would like doctors, researchers, investors, distributors, experts, and managers to participate in TamaBio and deliver cutting-edge technology to the world and to patients.
