Stryker Corp., a maker of artificial knees and hips, filed a patent-infringement lawsuit against Zimmer Holdings Inc. to block sales of a device that removes damaged tissue and cleans bones during joint surgery.
Stryker claims Zimmer’s Pulsavac Plus system infringes three U.S. patents and is seeking cash compensation and an order to prevent further use of the inventions, according to a complaint filed Dec. 10 in federal court in Kalamazoo, Michigan.
