Boston private equity firm Audax Group is buying Katena Products, which provides instruments to physician offices.
Katena, headquartered in Denville, New Jersey, also provides products to hospitals and surgical centers. The company supplies surgical instruments and single-use devices.
The business was sold by the Cortec Group, a New York private equity firm that bought it in 2009. Cortec focuses mainly on health care companies, and has more than $2 billion in capital under management.
Audax focuses on making middle-market deals has has about $6 billion in assets under management. The firm's recent investments include wire and cable connector business TPC Wire & Cable Corp., in May, and AllOver Media, an advertising company, in March.

William Blair & Co. advised Katena on the deal, and Kirkland & Ellis LLP was Audax' legal counsel.
