Nobody can say exactly how many women have had Essure implanted since the device went on the market in 2002. Bayer, which is headquartered in Germany, says that more than 750,000 devices have been sold worldwide and that sales “continue to grow.” (According to data from Essure clinical trials, device insertion fails anywhere from 4 to 12 percent of the time, making actual usage unclear.) In a telephone interview, Patricia Carney, director of U.S. medical affairs for Bayer Women’s Healthcare, pointed to the total sales number as evidence that “hundreds of thousands of women who’ve received Essure … successfully achieved permanent contraception without having to go through an invasive surgical procedure.”Share
In recent years, the Food and Drug Administration has received more than 16,000 adverse-event reports about Essure. These are official reports about symptoms, hospitalizations or diagnoses that patients, doctors, hospitals or a device manufacturer believe are associated with a device. They can prompt the agency to order a change in labeling, the addition of warnings or, in rare cases, the removal of a device from the market. Among the reports are nearly 9,000 surgical removals of Essure, mostly by hysterectomy. “That’s a lot of surgeries for a device that’s considered minimally invasive,” says Madris Tomes, a former FDA analyst. Although she and other experts in FDA law and regulation emphasize that there is no magic number of reports that will trigger an investigation, complaints can serve as an important signal to the FDA that it should take another look at a drug or device.
