BLOC Trial Summary

This trial is testing a new way to make sure a permanent birth control device is working properly, by comparing two different methods of imaging.

Who is the study for?
This trial is for women aged 21-45 who want permanent birth control. They must have had a regular menstrual cycle or been on hormonal contraceptives for the last three months, be sexually active with a male partner, and sure about ending their fertility. Women with prior tubal surgeries, abnormal bleeding, shellfish or iodine allergies, uncertainty about not having children, pregnancy, past endometrial ablation or gynecologic cancer cannot join.Check my eligibility
What is being tested?
The FemBloc Permanent Contraceptive System is being tested to see if it's an effective method of birth control without surgery. The study will check how well ultrasound compares to fluoroscopic hysterosalpingogram (a type of X-ray) in confirming that the fallopian tubes are blocked after using FemBloc.See study design
What are the potential side effects?
Potential side effects aren't specified here but may include discomfort during the procedure and possible allergic reactions in those sensitive to materials used in either FemBloc or imaging techniques.
