In 1974, our company advisers, Prof. Kazuhiro Hara and Prof. Yasuhito Takeuchi performed a disruptive breakthrough on Doppler based fetal monitoring system with “real time adaptive autocorrelation” method (1). Their innovation became a world-wide de-fact standard method in this field (2), implemented in virtually all the clinical fetal monitor in the world now.
Melody International Ltd. developed iCTG, which is a smallest fetal monitor in the world that uses a principle of “a real time autocorrelation”. Despite its size, iCTG has exact same functions as conventional machines. It has been approved by PMDA – Pharmaceuticals and Medical Devices Agency of Japan (Approval Number 230AFBZX00024000). Up until now, such devices were available only inside the hospital, but iCTG’s portability allows it to be used at any location.
It is also designed in a manner that even non-medical personnel can use it easily.
