The first component comprises an amine-containing polymer component at a concentration from about 0.1% weight by weight to about 13.65% weight by weight. The second component comprises a hydrophilic polymer or pre-polymer component at a concentration from about 3% weight by weight to about 35% weight by weight. The third component comprises an aldehyde component at a concentration from about 0.1% weight by weight to about 30% weight by weight. A method of repairing or supplementing a nucleus pulposus of an intervertebral disc comprises implanting the bioadhesive hydrogel composition in a patient.

摘要： The present invention preferably provides for a method of forming and the resulting solid polymer gel composition comprising polyethylene imine and at least one hydrogen bonding polymer. The composition has a greater viscosity than either of the polyethylene imine or the hydrogen bonding polymer alone and is injectable immediately after mixing of the polyethylene imine and the at least one hydrogen bonding polymer. A method of tissue repair may include mixing about 9.25% (w/w) to about 13.65% (w/w) polyethylene imine and about 18.02% (w/w) to about 26.62% (w/w) polyvinyl alcohol to form an injectable composition; injecting the injectable composition into a cavity within a human body; and allowing the composition to solidify in situ. A kit may include a multi-barrel syringe at least one barrel is loaded with polyethylene imine and at least another barrel is loaded with at least one hydrogen bonding polymer.
