23 Jul BIOLOGICAL IMPLANT
Abstract
Provided is a biological implant which exhibits high binding ability to a biological tissue after having been embedded in a living organism, which secures an appropriate strength depending on a site to which the implant is applied, and in which a micropore structural portion is less likely to be removed from a macropore structural portion. The biological implant includes a macropore structural portion which defines macropores of the biological implant, and a micropore structural portion which has micropores therein, the micropores having a pore size smaller than that of the macropores, the biological implant being characterized in that the macropore structural portion has substantially no pores therein; the micropore structural portion is provided on the surface of the macropore structural portion; the macropore structural portion and the micropore structural portion are formed of the same engineering plastic material; and the macropore structural portion is formed of a single material.
