Founded in 1975, Katena Premium Reusable Instruments is the brainchild of Kate Tiedemann. Kate left post-World War II Germany in 1955 speaking very little English. Over the course of the next two decades, Kate worked at three different micro-surgical instrument companies before founding Katena. While many aspects of the Katena brand have changed over the last 5 decades, the Katena brand still represents a commitment to excellence, exceptional quality, and valued surgeon partnerships.
