FemBloc Permanent Contraceptive
System Study
A study for women who want permanent birth control without surgery
This study will test the safety of the investigational FemBloc Permanent Contraceptive System in preventing pregnancy

Women choose their birth control method for many reasons: effectiveness, convenience, cost, side effects and whether they plan to have children in the future.

Currently, for women who no longer want children, surgery is the only permanent option. Either tubal ligation (“tying your tubes”) or a hysteroscopy surgery like “Essure®.” Some women who no longer want to have children may be choosing other methods of contraception because they don’t want to have surgery and an alternative simpler permanent solution is not available.

About FemBloc

The FemBloc Permanent Contraceptive System
consists of two steps:

1) FemBloc treatment is done using a catheter device that is similar to an intrauterine device (IUD). Instead of placing an IUD, that stays in the uterus, the FemBloc catheter device (called Delivery System) is placed in the uterus and a small amount of fluid (called Biopolymer) is delivered to each fallopian tube and then the catheter device is removed. Over time, the fluid causes the tube to react and become blocked similar to how your skin heals after a cut. The biopolymer is designed to break down over time and leave the body.

2) The natural blocking of your tubes takes several weeks. For 3 months after the procedure, you will need to use another method of birth control. The second part of the FemBloc System is a confirmation test using vaginal ultrasound with saline and air to check that your tubes are blocked. This test is done in your doctor's office.
