BSN Medical, the German bandages maker, has been put up for sale by Montagu, its UK-based private equity owner, which expects the planned €1.8bn-€1.9bn ($2.6bn-$2.8bn) auction to generate its biggest return for investors.

The sale would be the latest in a string of deals in the wound-care industry this year, after Bristol-Myers Squibb sold its ConvaTec business to private equity for $4.1bn and Johnson & Johnson received a bid for its Ethicon wound-care unit.
