Bayer Pharmaceuticals, manufacturer of the controversial Mirena intrauterine device (IUD), has acquired another device with a history of serious complications. The Essure system is a contraceptive device featuring two coils inserted into the fallopian tubes, which eventually causes the body to develop enough scar tissue to prevent pregnancy.
Similar to the Mirena IUD, patients have complained of serious complications, including pain, irritation and device migration. In one instance, a patient’s Essure system migrated after puncturing through the fallopian tube and uterus.
Bayer is already facing Mirena IUD lawsuits from some of the thousands of women who have issued complaints about the device. Women who use IUDs have alleged serious complications, including device migration and ectopic pregnancy, which occurs when a fetus develops outside of the uterus.
