ABSTRACT:
The medical material contains heparinized collagen in which heparin has been bonded to protamine covalently fixed on collagen, and, owing to its excellent compatibility with living bodies, especially, its superb antithrombotic property, can be suitably used as a substituent material for tissues or organs which are brought into direct contact with blood, namely, as aritificial vessels, artificial valves and patching materials for cardiovascular organs, and the above medical material is also suitable as a membrane having anti-adhesion effects. The medical material is obtained by immersing and treating a natural or artificial material successively in an aqueous protamine solution, an aqueous glutaraldehyde solution and an aqueous heparin solution.
