Eight study centers are led by a Colorectal Surgeon and seven centers are led by an Urogynecologist. This study is being conducted in compliance with Title 21 CFR Parts 11, 50, 54, 56, and 812; the principles of GCP as set forth in the World Medical Association Declaration of Helsinki (2008); and the ISO standard 14155:2011 (Clinical investigation of medical devices for human subjects - Good clinical practice).
