Baxter International Inc. (BAX) on Tuesday agreed to acquire the continuous renal-replacement therapy business of Edwards Lifesciences Corp. (EW) for as much as $65 million in a move to extend its renal-care business.

Under the agreement, expected to close in the third quarter, Baxter will initially pay $56 million and provide up to an additional $9 million if certain revenue targets are reached over the next two years.

For patients with life-threatening kidney injuries, continuous renal replacement therapy - or CRRT - provides continuous removal of excess fluid and waste that builds up with acutely impaired kidney function. It is usually administered at a hospital.

The move gives Baxter a line with which it is very familiar. Baxter supplies solutions used in CRRT treatment and is the exclusive distributor of Edwards' product in China, Latin America and the U.S. Europe and Australia will be among the markets Baxter will enter as part of the acquisition.

The product line is part of Edwards' Critical Care business and represented approximately $50 million in sales in 2008, primarily in Europe. The sale allows the company to "better focus on its global strategic priorities," said Critical Care executive Carlyn D. Solomon. "Baxter has been our long-term supplier and partner for this business and we believe this product line will thrive under Baxter's ownership."

Baxter has benefited from a broad product lineup that helps offset spending cutbacks by hospitals and patients - though it has been plagued by problems with its Colleague infusion pumps. In its most recent quarter, sales in the renal business fell 8% to $515 million but rose 1% excluding foreign-exchange impacts.

Shares of Baxter and Edwards were inactive premarket; they closed Monday at $50.47 and $65.65, respectively.
