Summary

This trial tests FemBloc, a device placed into the fallopian tubes through the vagina to block them permanently, without surgery. About 573 women aged 21-50 who want permanent birth control will be followed for up to 5 years to see how well it prevents pregnancy. The main goal is to measure the pregnancy rate after one year.
