Additionally, the Essure hysteroscopic sterilization procedure is not reversible. Because the fallopian tube tissue and coil implants grow together to create a closed passage, the micro-inserts cannot be surgically removed without damaging the fallopian tubes.
A tubal implant can also be difficult to insert, so a second procedure is sometimes necessary to completely block both tubes. In clinical studies, approximately 1 out of every 7 women were not able to have the coil-implants placed in both fallopian tubes during the first placement procedure.
