Orthopedic implant maker Stryker might tap its cash stockpile to purchase assets after completing its purchase of Boston Scientific's neurovascular unit, showing its willingness to diversify. Stryker has been buying a number of smaller companies recently, including the Sonopet ultrasonic device business, ulcer treatment maker Gaymar Industries and Porex Surgical products, Reuters notes. "All the big guys are looking for new avenues of growth," said Susquehanna analyst David Turkaly. "They have $2 billion in net cash that they are still sitting on, so I think you'll see them do more acquisitions." News
