Abstract
Novel polyglycerol aldehyde polymers are described. The polymers comprise glycerol monomers connected by ether linkages and have 3 to about 170 aldehyde groups per molecule. The polyglycerol aldehydes may be reacted with various amine-containing polymers to form hydrogel tissue adhesives and sealants that may be useful for medical applications such as wound closure, supplementing or replacing sutures or staples in internal surgical procedures such as intestinal anastomosis and vascular anastomosis, tissue repair, preventing leakage of fluids such as blood, bile, gastrointestinal fluid and cerebrospinal fluid, ophthalmic procedures, drug delivery, and preventing post-surgical adhesions.
