Preparation method of gradient mineralized cancellous bone matrix material
A gradient mineralized cancellous bone matrix material and a preparation method thereof are provided, and the preparation method includes: processing naturally-derived bone tissue with an immunogenicity removal treatment for decellularization, and processing an obtained decellularzed bone with a gradient demineralization treatment to obtain the gradient mineralized cancellous bone matrix material. The present invention expands a porosity of the bone matrix material and a collagen exposure degree on a surface thereof, which effectively releases growth factors and improves adhesion of the material to the cells, so as to up-regulate genes and proteins related to cell regeneration. The present invention not only retains the biomechanical properties and three-dimensional microstructure of natural bone ECM scaffolds, but also plays an active role for osteogenesis, angiogenesis and collagen mineralization in the early stage of fracture, thereby increasing engraftment adhesion of cells and promoting differentiation induction of cells.
FIBROUS BIRTH TISSUE COMPOSITION AND METHOD OF USE
A fibrous birth tissue composition fabricated from placental tissue is provided. Methods of processing a mammal’s placental tissue to form a fibrous birth tissue composition are provided. Regenerative methods are also provided.
Anisotropic biocomposite material, medical implants comprising same and methods of treatment thereof
Reinforced biocomposite materials. According to at least some embodiments, medical implants are provided that incorporate novel structures, alignments, orientations and forms comprised of such reinforced bioabsorbable materials, as well as methods of treatment thereof.
METHOD OF THE OSTEOREPARATIVE PROCESSES CORRECTION AND BONE DEFECT RESTORATION BY MEANS OF HUMAN CELL-BASED MEDICINAL PRODUCTS (CELL AND TISSUE TRANSPLANTS) AND METHOD OF THEIR MANUFACTURING
Method of the osteoreparative processes' correction and/or bone defect restoration by means of human cell-based products (cell and/or tissue transplants) and the method of its manufacturing. The invention a creates and establishes conditions for osteoreparative processes restoration in destroyed bone tissue by osteoreparation cell sources restoration as the result of use cell technologies and bone tissue engineering methods, e.g. scaffold-guided regeneration, particularly by means of cell transplantation by injection and/or transplantation of original three-dimensional osteoreparative prevascularized graft (3D-OPG). Manufacturing of medical products and preparations of the product based on human cells (cell and/or tissue transplants) is dedicated for impaired osteoreparative processes correction and/or bone defect restoration.
SYSTEMS AND METHODS FOR SIZING AND INTRODUCTION OF SOFT-TISSUE ALLOGRAFTS
The present disclosure includes systems, methods, kits, and individual tools (e.g., trial sizers and delivery devices) for medical procedures involving a soft-tissue allograft for the correction of skeletal impairments (e.g., misalignments, arthritis, etc.).
REMOVABLE BIOCOMPATIBLE SUBSTRATE FILTER FOR A REAMING AND COLLECTION DEVICE
The present invention provides for a removable second stage biocompatible substrate filter that includes biocompatible implant material configured to trap second stage operative particulate matter that may include at least one of bone fragments, plasma, stem cells, cellular matter, and growth factors captured from irrigation fluid. The second stage biocompatible substrate filter may be configured to combine with bone fragments captured from irrigation fluid by a first stage filter and may be configured to be operable with a reaming and collection device.
Two-paste cement-forming compositions
Injectable, ready-to-use two-paste cement-forming compositions comprise a first paste and a second paste. The first paste comprises a non-aqueous oil-based suspension of monocalcium phosphate monohydrate (MCPM) powder, at least one surfactant effective to improve compatibility of the oil and the MCPM, and an organic acid, with an oil to MCMP powder weight ratio of about 0.2 to about 0.5. The second paste comprises an aqueous suspension of β-tricalcium phosphate (β-TCP) powder and a gel-forming polymer, with a water to β-TCP powder weight ratio of about 0.3 to about 0.5. The molar ratio of β-TCP powder to MCPM powder is greater than 1. An article of manufacture comprises a first compartment in which the first paste is contained, and a second compartment in which the second paste is contained. The compositions are useful for bone repair or replacement.
BIOACTIVE SOFT TISSUE IMPLANT AND METHODS OF MANUFACTURE AND USE THEREOF
A bioactive filamentary structure includes a sheath coated with a mixture of synthetic bone graft particles and a polymer solution forming a scaffold structure. In forming such a structure, synthetic bone graft particles and a polymer solution are applied around a filamentary structure. A polymer is precipitated from the polymer solution such that the synthetic bone graft particles and the polymer coat the filamentary structure and the polymer is adhered to the synthetic bone graft particles to retain the graft particles.
MECHANICALLY ENTANGLED DEMINERALIZED BONE FIBERS
Demineralized bone matrix (DBM) compositions, methods of making and methods of treatment with the same are provided. The DBM compositions are made from mechanically entangled bone material that does not contain a carrier. The coherent mass of mechanically entangled demineralized bone fibers can be obtained by needle punching with barbed needles, entanglement with water or air jets, or by applying ultrasonic waves to the demineralized bone fibers. A coherent mass of mechanically entangled demineralized bone fibers can also be obtained by application to demineralized bone fibers of moisture, heat and pressure provided by pressure rollers. A method of making a bone material for hydration with a liquid is also provided. The method includes subjecting demineralized bone fibers to mechanical entanglement to obtain a coherent mass of demineralized bone fibers in the absence of a carrier. A method of treating a bone cavity with a mass of mechanically entangled demineralized bone fibers is also provided. The method of treatment includes implanting into a bone cavity a coherent mass of mechanically entangled demineralized bone fibers, wherein the coherent mass of mechanically entangled demineralized bone fibers does not contain a carrier.
