Abstract
An implantable support apparatus cushions between articulating structures, such as bone or other tissue. The apparatus includes a plurality of sheets of a substantially biocompatible tissue, which are connected together to form a laminated stack of the biocompatible tissue. Alternatively, the prosthesis may be formed of a molded protein, which has been cross-linked and substantially detoxified.
Claims20
An implantable orthopedic support apparatus, comprising:
- a plurality of generally flat sheets of a flexible tissue material comprising animal pericardium, the plurality of sheets being superimposedly connected together so as to inhibit movement between adjacent sheets, wherein the animal pericardium has been treated with an aldehyde solution and substantially detoxified.
An implantable orthopedic support apparatus, comprising:
- a plurality of generally flat sheets of a flexible tissue material, the plurality of sheets being superimposedly connected together so as to inhibit movement between adjacent sheets, the plurality of sheets including at least three similarly dimensioned and configured sheets of the flexible tissue material arranged in a substantially coaxial stack of the plurality of sheets, at least a substantial portion of the plurality of sheets have a generally circular cross section with a central aperture extending substantially coaxially through at least some of the plurality of sheets.
An implantable orthopedic support apparatus, comprising:
- a plurality of generally flat sheets of a flexible tissue material, the plurality of sheets being superimposedly connected together so as to inhibit movement between adjacent sheets, wherein first and second apertures extend substantially coaxially through at least a substantial portion of the plurality of sheets, the first and second apertures being spaced apart from each other at locations according to locations of a patient's lateral and medial menisci, whereby the apparatus forms a meniscal prosthesis.
A meniscal prosthesis for replacement of meniscus of a knee joint, comprising:
- a plurality of generally flat sheets of a flexible tissue material, the plurality of sheets being attached together substantially coaxially so as to inhibit movement between adjacent sheets the plurality of sheets, at least one aperture extending substantially coaxially through the plurality of sheets.
