Abstract
A hydrogel tissue adhesive formed by reacting an aldehyde-functionalized polysaccharide containing pendant aldehyde groups with a water-dispersible, multi-arm amine is described. The hydrogel may be useful as a tissue adhesive or sealant for medical applications that require a more rapid degradation time, such as the prevention of undesired tissue-to tissue adhesions resulting from trauma or surgery.
