Abstract
High concentration collagen compositions having improved persistence when administered for soft tissue augmentation are prepared from both cross-linked and non-cross-linked collagen starting materials. Suspensions of the starting materials are subjected to vigorous mechanical disruption to reduce the average collagen fiber size to below a threshold level which enhances the injectability of the composition. Thus, both enhanced injectability and enhanced persistence may be achieved using the same formulations.
