Abstract: The present invention provides a method for manufacturing a biomedical porous article wherein communicability between the pores in the porous article is ensured and a desired porosity can be easily obtained, the method comprising a plate-like thread cluster formation step in which a plate-like thread cluster is obtained by dispersing many metallic threads made of a biomedical metallic material along a flat surface and entangling them; a compressing step of compressing the plate-like thread cluster into a desired thickness; and a sintering step of sintering the plate-like thread cluster.

Abstract: A prosthesis for the replacement of hard tissues of human bones and joints, comprising a porous lamination component of metal thin sheets, each having a plurality of through holes and a thickness of 150 .mu.m or less, and being unharmful to the living body, the porous lamination component being formed such that the sheets are laid over one another and are then diffusion-bonded therebetween into one body by heating so that the through holes communicate with one another in the direction of the thickness thereof, and the prosthesis being entirely or partially composed of the porous lamination component. The present invention also relates to a method of making such a prosthesis. The present invention can provide prostheses which are not required to be replaced again, thereby imposing a less burden to patients.
