Abstract
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 µm 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.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
84 words
A prosthesis forthe 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 f..lm or less, and being unharmful to the living body, said porous lamination component being formed such that said thin sheets are laid over one another and then diffusion-bonded therebetween into one body by heating so that said through holes communicate with one another in the direction of the thickness thereof.
Claim 2
Dependent Claim
84 words
A prosthesis forthe 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 f..lm or less, and being unharmful to the living body, said porous lamination component being formed such that said thin sheets are laid over one another and then diffusion-bonded therebetween into one body by heating so that said through holes communicate with one another in the direction of the thickness thereof.
Claim 3
Dependent Claim
28 words
A prosthesis for the replacement of hard tissues of human bones and joints according to claim 1, wherein the prosthesis is entirely composed of said porous lamination component.
Claim 4
Dependent Claim
53 words
A prosthesis for the replacement of hard tissues of human bones and joints according to claim 1, wherein the prosthesis is partially composed of said porous lamination component at a desired surface portion of the prosthesis base being made of metal, inorganic or organic material to fabricate artificial bones, joints or other prostheses.
Claim 5
Dependent Claim
54 words
A prosthesis for the replacement of hard tissues of human bones and joints according to any of claims 1 through 3, wherein said porous lamination component is covered at a desired surface portion thereof by a covering metal material being highly bio-compatible and corrosion-resistive in the living tissues or highly bonding-affinitive to other prostheses.
Claim 6
Independent Claim
99 words
A method of making a prosthesis for the replacement of hard tissues of human bones and joints comprising the following steps of: perforating metal thin sheets, each having a thickness of 150 µm or less to provide a plurality of through holes, and being unharmful to the living body; laying said metal thin sheets thus obtained over one another so that said through holes may communicate with one another in the direction of the thickness thereof; and diffusion-bonding between said metal thin sheets into one body by heating so as to form a porous lamination component for the prosthesis.
Claim 7
Independent Claim
99 words
A method of making a prosthesis for the replacement of hard tissues of human bones and joints comprising the following steps of: perforating metal thin sheets, each having a thickness of 150 µm or less to provide a plurality of through holes, and being unharmful to the living body; laying said metal thin sheets thus obtained over one another so that said through holes may communicate with one another in the direction of the thickness thereof; and diffusion-bonding between said metal thin sheets into one body by heating so as to form a porous lamination component for the prosthesis.
Claim 8
Dependent Claim
45 words
A method of making a prosthesis forthe replacement of hard tissues of human bones and joints according to claim 5, wherein said laminating and diffusion-bonding are taken place at a desired surface portion of the base of the prosthesis of an artificial bone or joint.
