Omron Corp. said Wednesday it will acquire all shares in medical device maker Colin Medical Technology Corp. from U.S. investment fund Carlyle Group and other stockholders through a wholly owned unit in mid-June.

The acquisition, to be carried out through Omron Healthcare Co., is expected to cost nearly 10 billion yen, industry sources said.

Omron aims to expand the scope of its business by adding Colin Medical Technology's devices for medical institutions and health care professionals to its mainline home health care product lineups, company officials said.

"As we have strengthened our health-care-related operations, we can expect substantial synergic effects by acquiring Colin shares," Omron President Hisao Sakuta said at a news conference.
