In a bold move to expand its presence outside of the U.S., Cryolife Inc. revealed its plan to acquire Hechingen, Germany-based Jotec GmbH for an upfront payment of $225 million. The Kennesaw, Ga.-based company said it would close on the deal later this year. Jotec develops stent grafts and generated revenues of $50 million for the 12 months ending June 30.
