Abstract

Abstract A flexible, organic bone matrix which is adapted for use during the in vivo repair, replacement or reformation of preselected portions of a mammalian or animal skeletal system comprising a continuous sheet of completely or partially demineralized natural bone, wherein the thickness of said sheet is such that the sheet has sufficient flexibility to allow the sheet to be shaped to conform to the configuration of a skeletal region to be repaired and sufficient tensile strength to allow the sheet to be so shaped without damage to the sheet. The matrix is ultimately resorbed by the body thereby eliminating the need for supplemental surgery to remove the matrix, as is presently necessary when other exogenous, membrane materials are used. A method for the in vivo repair or replacement of a preselected section of a mammalian or animal skeletal system utilizing said matrix is also disclosed.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 15 words
A continuous sheet of partially or completely demineralised natural bone, said sheet being substantially flexible.
Claim 2
Dependent Claim 17 words
The sheet of claim 1, wherein the thickness of said sheet ranges up to about 10 millimetres.
Claim 3
Dependent Claim 19 words
The sheet of claim 1, wherein the thickness of said sheet ranges from about 0.05 to about 1.5 millimetres.
Claim 4
Dependent Claim 19 words
The sheet of claim 1, wherein the thickness of said sheet ranges from about 0.7 to about 1.2 millimetres.
Claim 5
Dependent Claim 24 words
A sheet according to any one of claims 1 to 4 for use in the repair, replacement or reformation of an animal skeletal system.
Claim 6
Dependent Claim 87 words
A flexible organic bone sheet comprising a sheet according to claim 5 for use in the repair, replacement or reformation of a preselected portion of an animal skeletal system wherein the thickness of the continuous sheet of partially or completely demineralised natural bone is such that the sheet has sufficient flexibility to allow the sheet to be shaped to conform to the configuration of a skeletal region to be repaired and sufficient tensile strength to allow the sheet to be so shaped without damage to the sheet.
Claim 7
Independent Claim 37 words
A method for the production of a sheet according to any one of the preceding claims comprising the steps of machining natural bone to form said continuous sheet, and of complete or partial demineralization of the bone.
Claim 8
Dependent Claim 25 words
A method according to claim 7 wherein the step of complete or partial demineralization of the bone is carried out subsequent to the machining step.
