If a hormonal birth control method is used for contraception, the subject must have been on said method for ≥ 3 months prior to enrollment and agrees to remain on the same hormonal regimen through the initial 12-month follow-up
• Able to provide written informed consent using a form that has been approved by the reviewing IRB/EC
