EXTRUSION PRINTING OF BIOCOMPATIBLE SCAFFOLDS
Compositions and methods for making biocompatible articles are provided. A method includes preparing a 3D printable mixture and depositing successive layers of the mixture in a predetermined pattern to form a porous biocompatible article. The predetermined pattern has a porosity suitable for a bone or cartilage scaffold. Associated 3D printable compositions and porous articles made from the described methods are also described. The preparing a 3D printable mixture can comprise conjugating an alkyne-terminated polymer to a peptide to form a peptide-containing composite, or providing a mixture that comprises a ceramic material and a binder, and wherein the 3D printable mixture comprises from 50 wt. % to 80 wt. % of the ceramic material.
Method and apparatus for treating bone fractures, and/or for fortifying and/or augmenting bone, including the provision and use of composite implants, and novel composite structures which may be used for medical and non-medical applications
A composite comprising: a barrier, said barrier being configured to selectively pass water, and said barrier being degradable in the presence of water; a matrix material for disposition within said barrier, wherein said matrix material has a flowable state and a set state, and wherein said matrix material is degradable in the presence of water; and at least one reinforcing element for disposition within said barrier and integration with said matrix material, wherein said at least one reinforcing element is degradable in the presence of water, and further wherein, upon the degradation of said at least one reinforcing element in the presence of water, provides an agent for modulating the degradation rate of said matrix material in the presence of water.
MEDICAL HONEYCOMB STRUCTURE AND METHOD FOR PRODUCING THE SAME, MEDICAL TISSUE RECONSTRUCTION BAG, AND MOLDING DIE
A medical honeycomb structure lacking at least a portion of an outer peripheral side wall of a honeycomb structure that includes a plurality of through-holes extending in one direction, wherein sites lacking the outer peripheral side wall have a plurality of grooves, and have a plurality of planes including distant surfaces of groove side walls flanked by the grooves.
Modeling devices used in guided bone and tissue regeneration
This disclosure describes manufacturing of a device configured to guide bone and tissue regeneration for a bone defect. A method may include receiving a three-dimensional digital model or scan representing an anatomical feature to be repaired, generating a simulated membrane using the three-dimensional model, the simulated membrane being configured to cover the anatomical feature to be repaired, generating a digital two-dimensional flattened version of the simulated membrane, and generating code or instructions configured to cause a three-dimensional printer or milling device to produce a trimming guide that includes an opening corresponding to the flattened version of the simulated membrane and that further includes a cut-out configured to hold a premanufactured membrane. The trimming guide may be operative as a guide for marking or cutting the premanufactured membrane through the opening while the premanufactured membrane is held in the cut-out.
Helical graft containment cage
A bone graft containment device includes a body formed via one or more helical structures extending about a longitudinal axis of the body from a first end to a second end to define a channel extending longitudinally therethrough. The channel is configured to receive a bone graft or bone graft substitute material therein, the one or more helical structures formed of a material permitting the body to be one of expanded, compressed and curved to fill a target space of a target bone.
BONE GRAFT MATERIAL FOR USE IN A SPINAL FUSION METHOD
The invention concerns a bone graft material for use in a spinal fusion method, wherein the material comprises i) a composition for forming a matrix, comprising at least a first matrix material precursor component and a second matrix material precursor component, capable of forming a matrix by crosslinking of the precursor components under appropriate conditions; and ii) a bioactive factor, which is biologically active to stimulate bone formation between two vertebrae, and for effecting or supporting spinal fusion; wherein the spinal fusion method comprises the steps of applying a cage in between the two vertebrae, which is not pre-filled with the bone graft material; and subsequently applying the bone graft material adjacent to and/or into the cage, such that essentially the entire remaining volume between the two vertebrae is filled with the bone graft material. The invention allows for ease of use while forming a more homogeneous matrix.
REPAIR OF SHOULDER-JOINT LESIONS
The present invention relates to bone-implants for treating a lesion on a bone, comprising: a bone anchor, a container in communication with the bone anchor and an osteoconductive bone-filler material inside the container, and methods thereof.
Tissue grafts and methods of making and using the same
In some embodiments, the present invention provides tissue grafts, such as vascularized bone grafts, and methods for preparing and using such tissue grafts. In some embodiments the tissue grafts are made using pluripotent stem cells, such as autologous pluripotent stem cells. In some embodiments, the tissue grafts are made by creating a digital model of a tissue portion to be replaced or repaired, such as a bone defect, partitioning the model into two or more model segments, and then producing tissue graft segments having a size and shape corresponding to that of the model segments. Such tissue graft segments may be assembled to form a tissue graft having a size and shape corresponding to that of the tissue portion to be replaced or repaired.
CUSTOMIZED THREE-DIMENSIONAL SCAFFOLD FOR ORAL AND MAXILLOFACIAL BONE GRAFTING
A customized resorbable three-dimensional scaffold for oral and maxillofacial bone grafting involves merging two sets of three-dimensional information obtained from a patient, the first set includes three-dimensional bone information and the second set includes three-dimensional teeth and tissue information. The merged information is used to generate a three-dimensional shape of the bone to be regenerated, a three-dimensional position of the missing tooth/teeth, and a three-dimensional model of the customized resorbable three-dimensional scaffold for oral and maxillofacial bone grafting. The three-dimensional model is used to generate the customized resorbable three-dimensional scaffold and resorbable connectors for the customized resorbable three-dimensional scaffold.
Components for artificial joints
A component of an artificial joint according to an exemplary aspect of the present disclosure includes, inter alia, a hollow tube including bone ingrowth material. Further, the hollow tube is selectively expandable. The bone ingrowth material allows the component to become biologically fixed to adjacent bone. Further, expansion of the hollow tube increases friction between the hollow tube and the adjacent bone, which increases stability.
