Essure is an office-based procedure done vaginally by passing an instrument into the uterus and then up into the fallopian tubes to deposit a coil that causes scarring and therefore blockage of the tubes preventing pregnancy. A second procedure similar to the first is required to confirm success several months later. This usually requires 3 months of birth control. Reported complications include its migration into the abdomen requiring surgical removal. Not all patients can have both tubes implanted; tubal pregnancies have been reported as well. Recovery takes about 1-14 days with the average recovery time being 3-5days.
