    摘要: The invention provides a self-sealing arteriovenous graft including a tube having a polymeric inner layer defining a lumen through which blood may flow and an outer textile layer. The outer textile layer is concentrically disposed about the inner layer. Furthermore, an intermediate self-sealing layer is concentrically positioned between the inner and outer layers. The self-sealing layer includes a biocompatible polymer.

    摘要: A medical material of the present invention comprises a polymer or copolymer of a vinyl derivative having a polar group, said polymer or copolymer containing an antiplatelet agent. Since the antiplatelet agent can be continuously dissolved in the active concentration, the material has high anticoagulant activity and inhibition action of platelet loss due to activation of platelet.

    摘要: An improved spacer material for improving the biocompatibility of a biomaterial and a method for making it in which a polyalkylimine is covalently attached to an aminated substrate and combined with a crosslinking agent which is at least difunctional in aldehyde groups. The polyalkylimine can be for example, polyethyleneimine and the crosslinking agent can be, for example, glutaraldehyde. Preferably, the crosslinking agent is applied in dilute solution and at a pH suitable to accomplish light crosslinking of the polyalkylimine and also provide aldehyde linkages at the interface between the biomolecule and the spacer.
