Clinical Trial Summary

The purpose of this study is to determine whether a Foley balloon is similar to osmotic dilators for preparing the cervix prior to a second trimester abortion. Procedure time will be used to compare the two different methods of cervical preparation, reflecting the ease at which the surgeon can perform through a prepared cervix. The aim is to expand effective options for cervical preparation that will can accommodate for varying patient characteristics and provider experiences.
