Title: POROUS BASE MATERIAL FOR TISSUE RECONSTRUCTION, ARTIFICIAL BLOOD VESSEL AND METHOD FOR PRODUCING SAME
Abstract:
Provided are a porous base material for tissue reconstruction, said porous base material having excellent cell infiltration properties and thus exhibiting excellent tissue reconstruction ability, and an artificial blood vessel. Also provided is a production method whereby the porous base material for tissue reconstruction or the artificial blood vessel can be easily produced. The porous base material for tissue reconstruction according to the present invention is a laminate consisting of at least two layers formed of bioabsorbable materials, characterized by comprising at least one ultrafine fiber nonwoven fabric layer and at least one porous layer having an average pore size of 0.1-800 μm, said porous layer being disposed on the surface of said ultrafine fiber nonwoven fabric layer.
