Medical device maker ClearStream Technologies said it agreed to be bought by New Jersey-based CR Bard for about 43.8 million pounds ($68.5 million) in cash. The company, whose medical devices are used to clear blocks in the coronary and peripheral arteries, said the offer had been pitched at 85 pence a share, at a premium of 84 percent to the stock's Monday close. Ireland-based ClearStream, which has been advised by finnCap, considers the terms of the offer fair and reasonable.
