Abstract:
The present invention is directed to injectable acid soluble collagen compositions comprising a neutralized solution of an acid soluble collagen, EDTA and preferably a polyol, wherein the composition is injectable at physiological pH and the acid soluble collagen polymerizes upon exposure to tissue. The invention is suitable for use in soft tissue augmentation, promoting soft tissue regeneration and coating medical implants and devices.
