Boston Scientific to Buy Meadox Medicals: Boston Scientific Corp. said it will extend its buying spree by acquiring Oakland, N.J.-based Meadox Medicals Inc., a closely held maker of vascular repair products, for about $457 million in stock. It marks the second buyout proposal in less than a month for the maker of catheters and other medical devices, putting Natick, Mass.-based Boston Scientific on the road to $2 billion in acquisitions this year. It is also the latest in a wave of mergers and acquisitions among medical products makers expanding product lines to stay competitive. Boston Scientific plans to combine Meadox’s woven, knitted and collagen-sealed grafts with its less-invasive surgical technologies, designed to speed recovery and reduce medical procedure costs.
