An arbitrator has ruled in favor of Medtronic Inc. in a patent dispute with Johnson & Johnson over the design of its stents, the tiny wire metal mesh used to prop open arteries.

Johnson & Johnson had alleged that Medtronic’s “Driver” stent and several other Medtronic stents infringed on patents owned by J&J’s stent unit, Cordis Corp. The arbitrator ruled that the stents were licensed under a 1997 agreement between the companies, Medtronic said on Thursday.
