Computer implemented methods of producing a bone graft are provided. These methods include obtaining a 3-D image of an intended bone graft site; generating a 3-D digital model of the bone graft based on the 3-D image of the intended bone graft site, the 3-D digital model of the bone graft being configured to fit within a 3-D digital model of the intended bone graft site; storing the 3-D digital model on a database coupled to a processor, the processor having instructions for retrieving the stored 3-D digital model of the bone graft and for combining a carrier material with, in or on a bone material based on the stored 3-D digital model and for instructing a 3-D printer to produce the bone graft. A layered 3-D printed bone graft prepared by the computer implemented method is also provided.

Computer implemented methods of producing a porous implant are provided including obtaining a 3-D image of an intended tissue repair site; generating a 3-D digital model of the porous implant based on the 3-D image of the intended tissue repair site. The method also includes determining an implant material and an amount of a porogen to add to an implant material to obtain a desired porosity of the porous implant. The desired porosity is based on a combination of macropores, micropores and/or nanopores structures. The 3-D digital model developed is stored on a database coupled to a processor, wherein the processor has instructions for combining the implant material with the porogen based on the stored 3-D digital model and for instructing a 3-D printer to produce the porous implant. A layered 3-D printed porous implant prepared by the computer implemented method is also provided.

The present disclosure provides a bone-implantable device and methods of use. The bone-implantable device comprises a body having an exterior surface, wherein a portion of the exterior surface includes a cured osteostimulative material comprising MgO.

An artificial acetabulum having a multilayer shell-core composite structure includes a ceramic acetabular liner, a transition layer and an acetabular shell. The acetabular shell is made of a porous metal, a porous alloy or a porous toughened ceramic; the ceramic acetabular liner is made of a ceramic material; and the transition layer is made of a composite material comprising materials of the acetabular shell and the ceramic acetabular liner. The artificial acetabulum is manufactured through sintering a green body of successively stacked layers of the ceramic acetabular liner, the transition layer and the acetabular shell, and the green body of successively stacked layers is obtained through a powder co-injection molding process. The ceramic acetabular liner of the artificial acetabulum has a high rigidness, corrosion-proof and wear-proof performance. The acetabular shell of the artificial acetabulum has a high toughness and shock resistant performance.

A biodegradable metallic vascular stent includes: a base body which is tubular with a lumen along a longitudinal axis, wherein the base body has a plurality of circumferential support structures which are successively positioned along the longitudinal axis. The circumferential support structures are each composed of a sequence of repeat units and has two or more connectors, wherein two adjacent circumferential support structures are joined together by at least one of the connectors, and each of the connectors is attached to one of arched elements in the repeat units of the two adjacent circumferential support structures to be connected. The biodegradable metallic vascular stent possesses suited radial pressure, flexibility and fatigue strength. Furthermore, the stent is design for peripheral vascular disease and coronary artery disease treatment as well.

The invention relates to a method for producing an implant, which is in particular in the form of a wound dressing. The implant consists of a sheet-like structure made of magnesium, which is embedded in a collagen non-woven fabric.

A raw material of aluminum base alloy is extruded and formed by using a forming pattern comprising an upper pattern having plural through-holes for supplying the raw material into diaphragms of equal angles on the circumference and circular cylindrical protrusions positioned in the center of plural through-holes so as to be surrounded by plural through-holes at the exit side of the through-holes, and a lower pattern positioned in the concave portions commonly penetrating at the exit of the plural through-holes of the upper pattern, having through-holes for inserting the protrusions of circular circumference of the upper pattern by providing a tube forming gap, positioned in the center of concave portions of the concave portions in the circular columnar shape of the upper pattern.

The invention relates to an implant for covering bone defects in the jaw region, which comprises a magnesium film.

A device for containing bone graft material comprises a body including an inner sleeve extending longitudinally from a proximal end to a distal end and an outer sleeve surrounding the inner sleeve and extending longitudinally from a proximal end to a distal end such that a bone graft collecting space is formed therebetween.

An intervertebral implant for insertion into an intervertebral disc space between adjacent vertebral bodies or between two bone portions. The implant includes a spacer portion, a plate portion operatively coupled to the spacer portion and one or more blades for securing the implant to the adjacent vertebral bodies. The blades preferably include superior and inferior cylindrical pins for engaging the adjacent vertebral bodies. The implant may be configured to be inserted via a direct lateral trans-psoas approach. Alternatively, the implant may be configured for insertion via an anterior approach.
