Claim Text:
1. A method for applying a coating to an anatomical site on tissue of a living organism comprising: applying to the site a) at least one dextran that has been derivatized to provide at least one aminodextran that contains primary amine groups, said at least one dextran having a weight-average molecular weight of about 1,000 to about 1,000,000 Daltons, said at least one aminodextran having an amine substitution level of about 5% to about 65%; followed by b) at least one dextran that has been oxidized to provide at least one oxidized dextran containing aldehyde groups, said at least one dextran having a weight-average molecular weight of about 1,000 to about 1,000,000 Daltons, said at least one oxidized dextran having an equivalent weight per aldehyde group of about 65 to about 1500 Daltons; or applying (b) followed by (a) and mixing (a) and (b) on the site; or premixing (a) and (b) and applying the resulting mixture to the site.
