A look back at Essure
It’s been almost 16 years since the Food and Drug Administration approved Essure in late 2002. Back then, Essure was created as an alternative to tubal ligation, a surgical procedure in which a woman’s “tubes are tied” — or, more accurately, clamped and sealed, resulting in sterilization and permanent birth control.
How does Essure work?
Essure implants consist of two tiny, implantable metal coils that are inserted into the fallopian tubes — a pair of tubes along which eggs travel from the ovaries to the uterus. Once inside the fallopian tubes, Essure implants cause scar tissue to gradually form, eventually blocking the tubes and preventing fertilization of a woman’s eggs. While tubal ligation is considered major surgery that requires local, general or spinal anesthesia, Essure involves a simpler procedure that can be done in a doctor’s office, with less anesthesia required.
