Abstract
The present invention discloses a novel, injectable crosslinked collagen composition which is able to continue crosslinking after injection to a soft or hard tissue site in order to anchor the collagen implant to the host tissue. The composition comprises particulate crosslinked collagen, noncrosslinked collagen (which may be fibrillar or nonfibrillar collagen), and a chemical crosslinking agent, such as synthetic hydrophilic polymer. Methods of augmenting soft or hard tissue using these injectable collagen compositions are also disclosed.
