Shanghai, China, 28 November 2024 — Shanghai MicroPort Medical (Group) Co., Ltd., in partnership with Shanghai Ninth People’s Hospital Affiliated to Shanghai Jiao Tong University School of Medicine, has recently introduced a prototype of its totally implantable cochlear implant (TICI).A cochlear implant is an active implantable medical device that restores hearing sensation for individuals with severe to profound hearing loss caused by inner ear damage.

中国上海，2024年11月28日-上海微孔医疗（集团）有限公司与上海交通大学医学院附属上海第九人民医院合作，最近推出了其全植入式人工耳蜗（TICI）的原型。人工耳蜗是一种主动植入式医疗设备，可恢复内耳损伤引起的严重至严重听力损失患者的听力。

Conventional cochlear implants consist of two components: an internal implant and an external sound processor. The external processor converts sound signals into electrical signals, which are then transmitted to the internal implant to stimulate the cochlear nerve, thereby enabling auditory function. TICI represents a transformative advancement in the field of hearing solutions.

传统的人工耳蜗由两部分组成：内部植入物和外部声音处理器。外部处理器将声音信号转换为电信号，然后将其传输到内部植入物以刺激耳蜗神经，从而实现听觉功能。TICI代表了听力解决方案领域的变革性进步。

Unlike conventional cochlear implant systems, all components of the TICI are implanted entirely under the skin, making it completely invisible externally. This innovation allows for 24-hour seamless sound access and indistinguishable appearance from others, encouraging more patients to consider this technology.The development of an implantable acoustic sensor and body noise cancellation technique has been one of the greatest challenges to overcome while developing TICI.

与传统的人工耳蜗系统不同，TICI的所有组件都完全植入皮肤下，使其在外部完全不可见。这项创新允许24小时无缝的声音访问和与其他人无法区分的外观，鼓励更多的患者考虑这项技术。植入式声传感器和体噪声消除技术的开发是开发TICI时需要克服的最大挑战之一。

Through close collaboration with Shanghai Ninth Hospital, MicroPort® has overcome this challenge by achieving breakthroughs in subcutaneous high-sensitivity acoustic sensing technology and body noise cancellation algorithm. Prof. Hao Wu, the project’s chief scientist, has highlighted the broad frequency response, wide dynamic range, and exceptional sensitivity of this prototype.
