Mirena® is an intrauterine contraceptive system, more commonly known as an IUD, that was approved by the FDA for use in the United States in 2000. It is designed, manufactured, marketed, and sold in the United States by Bayer Healthcare Pharmaceuticals, Inc., a New Jersey corporation, and other Bayer entities. Mirena® is a small T-shaped device made of soft flexible plastic that is inserted into a uterus and releases levonorgestrel to prevent pregnancy for up to five years. It is also used to treat heavy menstrual bleeding in women who choose IUD contraception. The complaints filed allege that the plaintiffs suffered injuries and/or damages as a result of misplacement of the Mirena® device. On May 13, 2013, the Supreme Court designated all pending and future litigation involving the Mirena® contraceptive device as multicounty litigation and assigned it for centralized management in Bergen County by Judge Brian R. Martinotti.
