Boston Scientific (NYSE:BSX) announced that it had bought Bayer's (NASDAQOTH:BAYRY) interventional division for $415 million last Thursday. The division, which makes products that help treat blood flow issues, makes sense as a bolt-on to Boston Scientific's peripheral interventional division. As the Minneapolis Star Tribune reports, this will give Boston roughly 40% share in the thrombectomy market when the deal closes in the second half of 2014. But why did Bayer make the sale?
