Inverting patterns turn the cut edges inward and minimize exposed suture. These are used to close lumens in large animal species (intestines, bladders, uteri). These patterns prevent leakage and minimize the risk of adhesions due to exposed suture. Small animal species are less prone to forming adhesions and other patterns may be used.
