SYSTEMS FOR CARTILAGE REPAIR
Neo-cartilage constructs suitable for implantation into a joint cartilage lesion in situ and a method for repair and restoration of function of injured, traumatized, aged or diseased cartilage. The construct comprises at least chondrocytes incorporated into a support matrix processed according to the algorithm comprising variable hydrostatic or atmospheric pressure or non-pressure conditions, variable rate of perfusion, variable medium composition, variable temperature, variable cell density and variable time to which the chondrocytes are subjected.
Powder compositions for generating cross-linked protein foams and methods of using thereof
In one embodiment, the present invention provides a composition, wherein the composition is a porous scaffold, wherein the pores of the scaffold are from 2 to 500 microns, the composition comprising: a) a cross-linkable protein selected from the group consisting of collagen and gelatin; b) a cross-linker which induces cross-linking of the cross-linkable protein; and c) a liquid.
Cell bandage
The invention provides a method for delivering cells across the surface of a tissue, the method comprising distributing the cells on and/or within a biomaterial to form a cell bandage and applying the cell bandage to the surface, wherein, after application of the cell bandage to the surface of the tissue, the cells are released from the cell bandage. Further provided is a method for bonding two or more tissues, the method comprising providing a cell bandage in intimate contact with the surfaces to be joined, wherein the cell bandage comprises a biomaterial, said biomaterial having cells distributed on and/or within it.
NOVEL THERAPEUTIC PRODUCTS AND ITS METHOD OF PREPARATION
The present invention provides novel therapeutic products which are used for treating chronic non healing wounds. The present invention is related to novel therapeutic products generated from peripheral blood mononuclear cells. The present invention also provides a process of preparing the therapeutic products, an aqueous suspension for Injection, gel and patch generated from peripheral blood cells in vitro having wound healing properties.
CELL-CONTAINING SHEET
In accordance with the present invention, an implant in which cells are arranged in a fine pattern that is available for immediate implantation and that does not need to be removed after implantation is provided. The present invention relates to a cell-containing sheet, which comprises cells and a support comprising a bioabsorbable material, in which the support has a cell adhesion protein-containing layer on the surface thereof and the cells form a pattern on the support.
Treatment of Arthritis and Other Musculoskeletal Disorders With Crosslinked Hyaluronic Acid
A method of treating a subject having a musculoskeletal disorder includes administering to a subject's articular site in need thereof an effective amount of a hyaluronic acid (HA) composition. In one embodiment, the HA composition includes an HA derivative, wherein carboxyl functionalities of the hyaluronic acid derivative are each independently derivatized to include an N-acylurea or O-acyl isourea, or both N-acylurea and O-acyl isourea. In another embodiment, the HA composition includes a crosslinked HA gel that is prepared by reacting an uncrosslinked HA with a biscarbodiimide in the presence of pH buffer in a range of between about 4 and about 8. The composite can optionally include at least one second bioactive agent other than the HA derivative, such as a steroid.
METHODS FOR REATTACHING DETACHED TISSUE TO HARD TISSUE USING BIOINDUCTIVE PATCH
A method for reattaching a detached tissue to a hard tissue includes operation in which a suture anchor having a first stitch and a second stitch is provided, wherein the first stitch is divided into a first strand and a second strand, and the second stitch is divided into a third strand and a fourth strand. The suture anchor is fixed on a hard tissue. The first strand, the second strand, the third strand and the fourth strand pass through a detached tissue. A bioinductive patch is provided, wherein the bioinductive patch includes a patch body and a button. The first strand and the third strand pass through the patch body and a first suture hole of the button, and the second strand and the fourth strand pass through the patch body and a second suture hole of the button. The second strand and the third strand are knotted to form a first strand node, and the first strand node presses the bioinductive patch and the detached tissue tightly onto the hard tissue.
METHOD FOR MANUFACTURING BIOINDUCTIVE PATCH
A bioinductive patch includes a patch body and a button. The patch body has an inner space. The button is disposed in the inner space of the patch body. A method for manufacturing a bioinductive patch includes step in which a patch body having an inner space is provided. The method continues with step in which a button is disposed in the inner space of the patch body.
