Practical application of language function monitoring system while operation (IEMAS),
which is shown an integrated heterogeneous biological information
IEMAS （Intraoperative Examination Monitor for Awake Surgery）
Based on the support from Ministry of Economy, Trade and Industry, we have developed the IEMAS jointly with Tokyo Women’s Medical University and Yasuhisa-KOKI Co., Ltd. since 2011 and have started to sell since Oct. 2015.
What's the operation under waking? Since the high order functional sites are asleep as well when they are given general anesthesia, there is no way to know the site. Therefore, he/she is made awaken from the general anesthesia and is performed an operation only by using tranquilizer and applying a local anesthesia The brain itself does not feel pain.
Result According to clinical evaluation, we can identify the high order functional sites of patient and we can lower the risk of sequela after enucleation.

Problem : Difficulty of the operation near “high order functional sites” of brain
When we have a small injury at brain in an operation, depending on the location of injury, we won’t be able to speak, read words, or calculate. These locations in brain are called “high order functional site”
(1) IEMAS shows a word or a picture to the patient at the right time and more visible.
(2) IEMAS shows all the information to the operating surgeon after consolidating in order for him/her to judge correctly.
(3) These information are recorded and we can reconfirm the result of test anytime. Therefore an unnecessary and a repeated operation can be avoided. By using IEMAS, the high order functional test can be done in many hospitals.
Aster Electric Co., Ltd. began manufacturing medical equipment since 1995 and develops and manufacture medical equipment for testing mainly at present.
