Brief summary

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.

Design outcomes

Primary

MeasureTime frameDescription
Number of confirmed pregnancies at 1 year among subjects told to rely on ESS505 for contraception1 yearEvaluated after 6000 women-months of reliance have been accumulated
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 attempted3 monthsEvaluated 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)

Secondary

MeasureTime frame
Number of confirmed pregnancies at 10 years among subjects told to rely on ESS505 for contraception10 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 tubeOn 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 assessedUp to 10 years
