MF-4181 for the Reduction of Scars Secondary to Abdominoplasty or Laparoscopy/Laparotomy Gynecologic Procedures

Study Overview
=================
Brief Summary
-----------------
The objective of the study is to evaluate the safety and preliminary efficacy of MF-4181, a hydrogel scaffold, in improving scars and their resulting consequences following abdominoplasty or laparoscopy/laparotomy gynecologic procedures.
