Cook Medical (Bloomington, Indiana) reported that it is suing Endologix (Irvine, California) claiming patent infringement on two of its endovascular stent-grafts. These tubes are used to repair arterial aneurysms.
Cook filed the lawsuit Tuesday in U.S. District Court in Southern District of Indiana.
"We have just become aware of the lawsuit filed by Cook alleging that Endologix infringes two of Cook's patents, one of which was granted in 1991 and the other in 1998," said Endologix CEO John McDermott in a statement. "The patent granted in 1991 expires next week. Together with our patent counsel, we are conducting a thorough evaluation and will provide more information as soon as available."
