Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
53 words
Implant intended for use in a bone, the surface of the implant having a micro-roughness with a pore size in the order of magnitude of 2µm and less, characterised thereby that this micro-roughness is superimposed on a macro-roughness with pore sizes of the surface of more than 10µm, preferably of more than 20µm.
Claim 2
Dependent Claim
62 words
Method for the manufacture of an implant according to claim 1, characterised thereby that the surface of the metallic body serving for the formation of the implant is blasted with a blasting medium, preferably corundum, for the production of a macro-roughness and that after the blasting a reducing acid is allowed to act on the body for the production of a micro-roughness.
Claim 3
Dependent Claim
23 words
Method according to claim 2, characterised thereby that HC1 or HF or a mixture of HC1 and H₂SO₄ is used as reducing acid.
Claim 4
Dependent Claim
19 words
Method according to claim 2 or claim 3, characterised thereby that the reducing acid is used in boiling state.
