Claims Analysis
Total Claims: 27
Claim 1
Independent Claim
49 words
A method of producing a flexible, biocompatible, and non-antigenic prosthesis of a predetermined shape, the method comprising: a) machining of a bone segment into a de- sired predetermined shape, GB2175807A 4 b) selectively demineralizing said bone segment to achieve the desired degree of flexibility, c) tanning said bone segment.
Claim 2
Independent Claim
49 words
A method of producing a flexible, biocompatible, and non-antigenic prosthesis of a predetermined shape, the method comprising: a) machining of a bone segment into a de- sired predetermined shape, GB2175807A 4 b) selectively demineralizing said bone segment to achieve the desired degree of flexibility, c) tanning said bone segment.
Claim 3
Dependent Claim
13 words
The method of claim 1 wherein the bone segment is tanned with glutaraldehyde.
Claim 4
Dependent Claim
21 words
The method of claim 1 additionally cornprising extracting the bone segment with an organic solvent to increase the matrix poro- sity.
Claim 5
Independent Claim
21 words
The method of claims 1 or 3 additionally comprising treating the bone segment with a protease to increase the matrix porosity.
Claim 6
Independent Claim
14 words
The method of claims 1, 2, or 3 ad- ditionally comprising sterilizing the prosthesis.
Claim 7
Dependent Claim
40 words
The method of claim 2 wherein the bone segment is treated with glutaraldehyde under tanning conditions effective in cross-linking available proteins to a degree sufficient to sta- bilize and strengthen the bone and to render it biocompatible and non- antigenic.
Claim 8
Dependent Claim
24 words
The method of claim 6 wherein tanning is accomplished by submerging the bone segment in a buffered solution comprising 0.2% to 0.8% (w/v) glutaraidehyde.
Claim 9
Dependent Claim
20 words
The method of claim 7 wherein the bone segment is submerged in a buffered solution comprising about 0.6% (w/v) glutaraidehyde.
Claim 10
Independent Claim
23 words
The method of claims 6, 7 and 8 wherein the bone is tanned with glutaral- dehyde for a minimum of about one month.
Claim 11
Dependent Claim
23 words
The method of claim 1 wherein the bone segment is derived from the condylar region of an allogenic or xenogenic long bone. 100
Claim 12
Dependent Claim
20 words
The method of claim 1 wherein demineralizing the bone segment is accomplished by submersion in a solution comprising an acid.
Claim 13
Dependent Claim
11 words
The method of claim 11 wherein the acid is I-ICI. 105
Claim 14
Dependent Claim
15 words
The method of claim 11 wherein said solution additionally comprises up to 1 % EDTA.
Claim 15
Dependent Claim
24 words
The method of claim 1 additionally cornprising submerging the bone segment in etha- nol to defat it and to remove machine oils and debris.
Claim 16
Independent Claim
53 words
A method of producing a flexible, biocompatible, and non-antigenic prosthesis of a predetermined shape, the method comprising: a) pulverizing a bone segment, b) demineralizing the resulting pulverized bone, c) tanning the bone with glutaraldehyde d) combining said pulverized bone with a carrier, e) molding or casting the combined material into the desired shape.
Claim 17
Independent Claim
53 words
A method of producing a flexible, biocompatible, and non-antigenic prosthesis of a predetermined shape, the method comprising: a) pulverizing a bone segment, b) demineralizing the resulting pulverized bone, c) tanning the bone with glutaraldehyde d) combining said pulverized bone with a carrier, e) molding or casting the combined material into the desired shape.
