On April 16, 2013, Volcano Corporation (the “Company”) filed suit in Federal District Court in Delaware against St. Jude Medical, Cardiovascular and Ablation Technologies Division, Inc., St. Jude Medical, Cardiology Division, Inc., St. Jude Medical, U.S. Division, St. Jude Medical S.C. Inc., and St. Jude Medical Systems AB, (collectively, “St. Jude”) for infringement of Volcano's recently issued United States Patent Nos. 8,419,647 and 8,419,648 both entitled “Ultra Miniature Pressure Sensor.” Volcano's complaint accuses St. Jude's PressureWire™ Certus and PressureWire™ Aeris cardiac pressure sensing guide wire products (the “Accused Guide Wires”) and St. Jude's RadiAnalyzer™ Xpress Measurement System, Ilumien™ PCI Optimization System and Quantien™ Integrated FFR Platform, which are used with the Accused Guide Wires, of infringing the patented methods of United States Patent No. 8,419,647. Volcano's complaint also accuses the Accused Guide Wires of infringing the patented device claims of United States Patent No. 8,419,648.
