Baxter International Inc., the U.S. maker of blood products and intravenous drugs, agreed to buy Swedish kidney-dialysis competitor Gambro AB for $2.8 billion to expand its dialysis-equipment business.

Gambro had about $1.6 billion in sales last year, Deerfield, Illinois-based Baxter said today in a statement. Gambro is jointly controlled by Sweden’s EQT Partners AB and Investor AB, the investment firm controlled by Sweden’s billionaire Wallenberg family. Including net debt, the deal is valued at $40.2 billion, Gambro said in a statement.
