Cardinal Health has reached a definitive agreement to acquire Viasys Healthcare for approximately $1.5 billion, including the assumption of outstanding debt.

Viasys Healthcare, a medical technology company with $610 million of revenue in 2006, specializes in respiratory care, developing and marketing systems for critical care and diagnostic use, as well as neurological, audio, and vascular diagnostics.

The acquisition will expand Cardinal Health’s clinical and medical product offerings for global, acute-care customers and will also provide a range of complementary products to the company’s medical disposables business and will leverage its integrated hospital selling organization in the U.S.

Upon completion of the merger, Viasys will become a wholly owned subsidiary of Cardinal Health. The transaction is expected to be completed this summer.
