Essure Contraceptive Implants: What you need to know about these controversial implants
For a long time, women who wanted permanent contraception had no choice but to resort to tubal ligation. Then in 2002, the Essure implant arrived on the market, distributed by the Bayer laboratory. Already widely used in the United States, the Essure implant is then offered to women of age and of childbearing age wishing to have no more children. Effective and non-invasive, he quickly conquers a large number of women. Bayer evokes 1 million units sold worldwide, including 240,000 in France.
The Essure implant: how does it work?
The principle of the Essure implant is to block the passage of sperm in the fallopian tubes. This is a flexible and flexible implant that the doctor will place with a hysteroscope directly by natural route in each of the two tubes. After three months, a tissue forms around the implant, blocking the tubes and preventing sperm from reaching the egg. Without hormones, the implant has no impact on the menstrual cycle.
Chronology of the case until removal of the Essure implant
In the United States, France and Brazil, the method is quickly challenged and many women report adverse side effects: pelvic pain, bleeding, device migration, joint, muscle or neurological disorders, orl, allergic reactions. Symptoms that may appear several months or even years after implantation. Between 2003 and 2017, 1087 are facing a problem with the implant or side effects.
- From 2015, the National Agency for Drug Safety (ANSM) puts the device under enhanced surveillance and recommends better control of the laying practices.
- In April 2017, a first favorable benefit / risk ratio is published. However, the experts insist on the need not to skip the necessary radiographic inspection stage three months after the installation.
- In August 2017, the Essure implant was withdrawn from the European market before its commercialization was definitively stopped 3 months later.
- The United States is still waiting a year and then withdraw Essure from the market in December 2018.
- April 2019: 70 patients file a lawsuit against X at the tribunal de grande instance in Marseille for "involuntary injuries, endangerment and, possibly, aggravated deception ".
The fight of an association of patients
While Bayer continues to deny any problems with the Essure implant, Alert Contraception, an association of patients, is at the initiative of a scientific study to understand these side effects. Isabelle Ellis, the president of the association, explained last April Parisian the purpose of this study " This is the first time a team in the world will do this research. The idea is to see if the heavy metals that make up Essure such as nickel, chromium, titanium or iron are released into the body of women. In short: do they pass into the tissues, into the blood then into the whole body, thus causing low-level intoxication of the patients? This could explain their neurological, muscular, articular symptoms ... ".
