Disclosed is the use of a biodegradable, moisture-curable isocyanate-functional composition in the manufacture of an adhesive for adhering biological tissue, the isocyanate functional composition comprising the reaction product of: (a) a multi-functional isocyanate component having an average functionality of h, wherein h is at least 2; and (b) a multi-functional active hydrogen component comprising at least 30 percent by weight, based upon the total weight of the multi-functional active hydrogen component, of a multi-functional active hydrogen reactant having an equivalent weight (equivalent weight divided by hydroxyl functionality) less than 100, wherein a ratio R of active hydrogen groups to isocyanate groups is selected such that l/h <R < 0.9.
