Executive Summary
The US heart valve supplier Edwards Lifesciences has launched another lawsuit against Medtronic, accusing it of infringing patents related to heart valve repair. The new suit, filed in the US district court in Delaware, alleges that Medtronic's Duran range infringes Edwards' patent on annuloplasty ring delivery systems used in surgical suturing. Last year Edwards sued Medtronic claiming that various products, including Duran and the Hancock II and Mosaic aortic heart valves, infringed three other Edwards patents. Medtronic is contesting the suits. It claims that it is not infringing the Edwards patents and that they are invalid anyway.
