About this study
Official title: A Multi-Center, Multi-National Clinical Study to Evaluate the Safety and Effectiveness of the Essure® (Model ESS505) Device to Prevent Pregnancy in Women Who Are Seeking Permanent Contraception
The Essure System is indicated for women who desire non-incisional permanent birth control (female sterilization) by occlusion of the fallopian tubes. The objective of the study is to evaluate the safety and effectiveness of the Essure System (Model ESS505) for permanent birth control in preventing pregnancy. The Essure ESS505 System includes a design modification that will be studied to determine if it provides immediate birth control, thereby removing the three months waiting period required for the commercially available Essure System Model 305 to be effective.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
ESS505 (BAY1454033)Device
| Study group | Role | What they receive |
|---|---|---|
| ESS505 | Experimental | All subjects that sign the informed consent and meet the eligibility criteria will be scheduled for an implant procedure. Receives: Device: ESS505 (BAY1454033) |
What is being measured
The primary outcome is the main question the study is designed to answer.
Number of confirmed pregnancies at 1 year among subjects told to rely on ESS505 for contraception
Evaluated after 6000 women-months of reliance have been accumulated
Measured: 1 year
Reliance rate, defined as number of subjects told to rely on ESS505 after the Essure confirmation test divided by the number of subjects who had insert placement attempted
Evaluated after 3000 women-months of reliance have been accumulated (expected at the same time most subjects with implants have completed their 3 month follow-up visit)
Measured: 3 months
Secondary outcomes (3)
Number of confirmed pregnancies at 10 years among subjects told to rely on ESS505 for contraception
Measured: 10 years
Safety of the ESS505 placement procedure defined as number of subjects who experience an AE assessed as related to the ESS505 placement procedure divided by the number of subjects in who at least one ESS505 was introduced into the fallopian tube
Measured: On day of placement procedure
Safety of subsequent wearing of the insert defined as number of subjects who experience an AE assessed as related to wearing of ESS505 divided by the number of subjects in whom the presence of an AE could be assessed
Measured: Up to 10 years
