Abstract
Abstract Bone augmentation in a mammalian body by insertion of a mesh comprising one or more fibrillar wires having a coating into a bone cavity or socket. The one or more fibrillar wires are arranged or assembled into a woolly structure, which may be infused or cultured with a bone morphogenic protein. The mesh is sealed in the cavity to permit new bone to form over time, resulting in an osteointegrated matrix of bone reinforced by the fibrillar wires of the mesh.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
91 words
A method of bone augmentation to support a prosthetic implant device comprising the steps of: (a) inserting a mesh into a cavity of a bone, the mesh comprising one or more fibrillar wires having a hydroxy appetite coating, the one or more fibrillar wires being arranged into a woolly structure; (b) sealing the mesh in the cavity; (c) permitting the bone to grow into the cavity until an osteointegrated matrix is formed; (d) coring the osteointegrated matrix to create an opening; and (e) inserting the prosthetic implant device in the opening.
Claim 2
Independent Claim
91 words
A method of bone augmentation to support a prosthetic implant device comprising the steps of: (a) inserting a mesh into a cavity of a bone, the mesh comprising one or more fibrillar wires having a hydroxy appetite coating, the one or more fibrillar wires being arranged into a woolly structure; (b) sealing the mesh in the cavity; (c) permitting the bone to grow into the cavity until an osteointegrated matrix is formed; (d) coring the osteointegrated matrix to create an opening; and (e) inserting the prosthetic implant device in the opening.
Claim 3
Dependent Claim
24 words
The method according to claim 1 further comprising the step, after step (a), of: adhering the woolly structure to the bone with an adhesive.
Claim 4
Dependent Claim
13 words
The method according to claim 2 wherein the adhesive comprises a fibron glue.
Claim 5
Dependent Claim
25 words
The method according to claim 1 further comprising the step of: energizing the mesh so as to promote growth of the bone into the cavity.
Claim 6
Dependent Claim
30 words
The method according to claim 4 wherein the step of energizing the mesh comprises the step of: applying an electrical current in the range of 5-25 microamperes to the mesh.
Claim 7
Dependent Claim
27 words
The method according to claim 1 wherein the one or more wires comprise a metal selected from the group consisting of titanium, tungsten, gold, and stainless steel.
Claim 8
Dependent Claim
13 words
The method according to claim 6 wherein the wires include an oxide layer.
Claim 9
Dependent Claim
22 words
The method according to claim 1 wherein the mesh is cultured with a bone morphogenic protein prior to insertion into the cavity.
Claim 10
Dependent Claim
20 words
The method according to claim 1 wherein the wires have a thickness in the range of 100 to 300 microns.
Claim 11
Dependent Claim
13 words
A method according to claim 1 wherein the hydroxy appetite coating is diffuse.
Claim 12
Dependent Claim
28 words
A method according to claim 1 wherein step (b) comprises the step of: covering the cavity with a barrier membrane to prevent epithelial tissue attachment to the mesh.
Claim 13
Dependent Claim
15 words
The method according to claim 11 wherein the barrier membrane comprises a bio-absorbable polymer membrane.
