摘要:
The present invention relates to trans-capsularly administering into a diseased joint a high specificity antagonist selected from the group consisting of: i) an inhibitor of a pro-inflammatory interleukin; ii) an inhibitor of TNF-α synthesis; iii) an inhibitor of membrane-bound TNF-α; iv) an inhibitor of a natural receptor of TNF-α; v) an inhibitor of NO synthase, vi) an inhibitor of PLA2 enzyme; vii) an anti-proliferative agent; viii) an anti-oxidant; ix) an apoptosis inhibitor selected from the group consisting of EPO mimetic peptides, EPO mimetibodies, IGF-I, IGF-II, and caspase inhibitors, and x) an inhibitor of MMPs; and xi) an inhibitor of p38 kinase.
摘要:
A reconstructive structure for a cartilaginous element having a plurality of superimposed layers of a small intestine submucosa compressed and secured together and shaped to provide the multi-layered reconstructive element of the anatomical shape of the cartilaginous element to be constructed. The method of forming the reconstructive structure includes superimposing the planar layers of the small intestine compressing, securing and cutting to the desired shape. The superimposing is performed so as to maintain the layers substantially planar prior to compressing and securing. The method of reconstructing a cartilaginous element includes removing at least a portion, if not substantially all of the cartilaginous element, but leaving a seed portion, sculpturing the reconstructive structure to the anatomical shape of the cartilaginous element to be reconstructed; positioning the receptive element adjacent to the seed portion and securing it thereto. To reconstruct a joint having two bones separated by a cartilaginous material, the method includes removing any remaining portions of the cartilaginous material down to a bleeding bone site and positioning and securing the reconstructive element to the bleeding bone site. A barrier layer may be provided between the bleeding bone site and the reconstruction element. Also, a defect site without a bleeding bone site may be created and used with a reconstructive element.

An orthopaedic device for repairing and regenerating cartilage includes a plug configured to be positioned in a hole formed in the cartilage and an anchor configured to support the plug. One or both of the plug and the anchor may be formed from naturally occurring extracellular matrix such as small intestine submucosa. A method for repairing and regenerating cartilage is also disclosed.

Bioprosthetic devices for soft tissue attachment, reinforcement, or construction are provided. The devices comprise a sheet of naturally occurring extracellular matrix and a sheet of synthetic mesh coupled to the naturally occurring extracellular matrix portion.
摘要:
A bioprosthetic device is provided for soft tissue attachment, reinforcement, and or reconstruction. The device comprises a naturally occurring extracellular matrix portion and a synthetic portion. In illustrated embodiments, the naturally occurring extracellular matrix portion comprises layers of small intestine submucosa, and the synthetic portion comprises one or more rows of fibers or mesh positioned between layers of the small intestine submucosa.

A method of making an implantable scaffold for repairing damaged or diseased tissue includes the step of suspending pieces of an extracellular matrix material in a liquid. The extracellular matrix material and the liquid are formed into a mass. The liquid is subsequently driven off so as to form interstices in the mass. The scaffold may further comprise biological agents that promote tissue repair and healing. Porous implantable scaffolds fabricated by such a method are also disclosed.
摘要:
A method of reconstructing a joint having two bones separated by cartilaginous material is provided. The method comprises the steps of removing a portion of the cartilaginous material to create a defect site, positioning an anatomically shaped reconstructive structure comprising multiple layers of submucosa and having a thickness of about 1 to about 12 millimeters adjacent to the defect site, and securing the reconstructive structure to the defect site. The method can further comprise the steps of positioning a barrier layer between the bleeding bone and the reconstructive structure, securing the barrier layer to the bleeding bone, and securing the reconstructive structure to the barrier layer.
