Medical Devices and Other Equipment Developed in Collaboration Under the Framework

Development of World’s First Open-Thoracotomy Training Chest Wall Model Replicating the Full Muscular Layer Structure

Researchers at Kobe University’s Graduate School of Medicine Department of Medical Device Engineering, Division of Medical Engineering Innovation (Part-time Lecturer and Visiting Professor Yugo Tanaka, and Specially Appointed Professor Takahiro Yasuda) have jointly developed a chest wall model for thoracotomy training in collaboration with WetLab Incorporated (Headquartered in Otsu, Shiga Prefecture; CEO/President Yoshio Okano).

This chest wall model is the world's first open thoracotomy training model developed that focuses on both ease of use and realistic simulation. In the field of thoracic surgery where minimally invasive medical procedures, including robotic surgery and video-assisted thoracoscopic surgery(VATS) have become standard in thoracic surgery, opportunities to gain experience with open surgery have diminished. This model offers especially valuable training opportunities for early-career physicians with limited exposure to open thoracotomy, thereby enhancing the quality and safety of patient care.

Industry–Academia Collaboration Leads to the Joint Development and Commercialization of the “Polymate Go” Wearable EEG System
— Enabling the Application of Home-Based EEG Monitoring to Facilitate the Diagnosis of Epilepsy

Kobe University’s Graduate School of Medicine, Division of Medical Device Systems, (Specially Appointed Professor Takahiro Yasuda), in collaboration with the Department of Clinical Neurology, Graduate School of Medicine and Faculty of Medicine, Kyoto University (Professor Riki Matsumoto), and Miyuki Giken Co., Ltd. (Head Office: Bunkyo-ku, Tokyo: President and Representative Director: Ryuzo Mase), has jointly developed the "Polymate Go," a wearable electroencephalography (EEG) system expected to enable continuous EEG monitoring in settings that more closely reflect patients' everyday living environments.

This achievement represents a successful example of translating research outcomes generated at a university into a medical device that can be used in actual clinical practice. The technology is expected to contribute to the advancement of home healthcare and community-based medicine.

Joint Development and Launch of the “Safety Forceps”

Mr. Sotaro Ishihara of the Department of Clinical Engineering, Kobe University Hospital, in collaboration with Nara Seiko INC., developed the Safety Forceps, a medical device intended to prevent the inadvertent cutting of dialysis tubing in clinical dialysis practice. The device (Medical Device Notification No. 29B1X00001000102) became commercially available in March 2026.

Mr. Sotaro Ishihara was also awarded the Excellence Award at the 9th Medical–Engineering Collaboration Award, in recognition of his achievements in the development and refinement of medical devices and healthcare tools that improve patients' quality of life, enhance the efficiency of healthcare professionals, and advance safety in medical practice.

Feature Article Published: “Medical Device Innovation through the Japanese-Style Ecosystem”

On June 23, 2023, Harvard Business Review published an interview article titled “Medical Device Innovation through the Japanese-Style Ecosystem” featuring Kobe University.
Professors Takahiro Yasuda and Yoshihiro Muragaki from the Graduate School of Medicine Department of Medical Device Engineering and the Center for Advanced Medical Engineering Research & Development (CAMED), discussed the formation of a Japanese-style ecosystem and the future direction of innovative medical device development.

Joint Development of an Otolaryngology Videoscope

On June 26, 2023, Nipro Corporation and its subsidiary, MACHIDA Endoscope Co., Ltd., together with Professor Kenichi Nibu from the Department of Otolaryngology–Head and Neck Surgery, Part-time Lecturer Dr. Go Inokuchi from the Division of Medical Device Systems, Department of Medical Device and Systems Development, Graduate School of Medicine, and Specially Appointed Professor Yoshiaki Fujiwara from the Device Development Promotion Division of the Kobe University Center for Advanced Medical Engineering Research and Development, announced the joint development of an otolaryngology videoscope.

OFDI Intravascular Imaging System

In collaboration with Terumo Corporation, we successfully expanded the clinical application of the OFDI (Optical Frequency Domain Imaging) Intravascular Imaging System, which uses near-infrared light to visualize cross-sectional images of blood vessels. Previously, its use had been limited to the coronary arteries of the heart. However, in June 2021, regulatory approval under Japan’s Pharmaceuticals and Medical Devices Act (PMD Act) was obtained for use in the lower limb arteries—from the thigh to below the knee—and in November of the same year, the system was approved for insurance coverage. Among optical coherence-based diagnostic devices employing similar principles, the OFDI system became the first in Japan to receive approval for use in lower limb arteries. The project was initiated by the hospital’s Department of Cardiovascular Medicine and achieved approval following a physician-led, multicenter clinical trial.

Software for Real-time Detection of Non-Convulsive Epileptic Seizures in EEG

On October 10, 2020, the final round of the 3rd MedTech Grand Prix KOBE, a contest focused on next-generation health and medical technologies, was held with 12 finalist teams selected from 106 applicants. The team “Protect Kid’s Brain,” led by Professor Hiroaki Nagase (Department of Pediatrics, Division of Pediatric Acute Diseases, Graduate School of Medicine, Kobe University), presented their project under the theme “Protecting Children’s Brains and Hearts from Non-Convulsive Epileptic Seizures.” The team received the ExaWizards Award, presented by the sponsor company ExaWizards Inc., and also won first place in the audience vote. This project is being advanced through medical-engineering collaboration with Professor Zhiwei Luo from the Graduate School of System Informatics. Moving forward, the team plans to integrate the software into existing electroencephalography (EEG) devices and evaluate its performance in clinical settings.
