Document Type and Number:
WIPO Patent Application WO/2003/034945
Kind Code:
A1
Abstract:
It is intended to provide an artificial vessel, which is excellent in biocompatibility, mechanical strength, antithrombotic properties, etc. and free from blood leakage and can be easily produced. An artificial vessel being free from blood leakage and excellent in antithrombotic properties, having almost smooth inner surface and showing favorable mechanical properties can be obtained within a short period of time by immersing a biologically active substance in a solution capable of setting to gel to give a solution containing the biologically active substance, incorporating this solution containing the biologically active substance into pores of a tube−shaped porous base material for artificial vessel, and then allowing the solution containing the biologically active substance, which has been incorporated into the pores of the porous base material for artificial vessel, to set to gel.
