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.

An artificial femoral ball head having a multilayer shell-core composite structure includes a spherical shell layer, a transition layer and an inner core. The inner core is made of a toughened ceramic, the spherical shell layer is made of a ceramic material, and the transition layer is made of a composite material comprising materials of the inner core and the spherical shell layer. The artificial femoral ball head is manufactured through sintering a green body of successively stacked layers of the spherical shell layer, the transition layer and the inner core, and the green body of successively stacked layers is obtained through a powder co-injection molding process. The spherical shell layer of the artificial femoral head has a high rigidness, corrosion-proof and wear-proof performance. The inner core of the artificial femoral head has a high toughness and shockresistant performance.

The invention relates to biomimetic, biodegradable composites including a magnesium (Mg) alloy mesh and a polymer/extracellular matrix (ECM). These hybrid composites, more particularly, are useful for the fabrication of medical implant devices, e.g., scaffolds, and are effective for bone regeneration. The fabrication process includes creating the Mg alloy mesh, and concurrently electrospinning the polymer and electrospraying the ECM onto the mesh.

A wound dressing and a method for production thereof. The wound dressing includes a collagen-containing sheet-like structure, which is made of magnesium or a magnesium alloy. The sheet-like structure has openings and is embedded in a collagen-containing sheet-like structure. The wound dressing is embodied as a geometrically stable bioresorbable membrane and includes a support made of a collagen membrane, on which the collagen-containing sheet-like structure is arranged.

A stent has a circumference and a plurality of members that define a lumen. The stent has three stable states, which include an unexpanded state, a partially deployed state, and a deployed state. The lumen has a first cross-sectional shape in the unexpanded state, a second cross-sectional shape in the partially deployed state and a third cross-sectional shape in the deployed state. The first cross-sectional shape of the lumen is different from the second and third cross-sectional shapes of the lumen, and the first cross-sectional shape of the lumen is a non-round shaped cross-sectional shape.

Systems, methods, and devices for bony fusion are disclosed. A threaded cannulated implant may be inserted into a target space, such as in the sacroiliac joint. The implant may have a distal section, a proximal section, and a central section between the distal section and the proximal section. The distal section may comprise cutting threads and flutes for self-drilling the implant into bone. The proximal section may be configured to couple to an insertion instrument for the implant. The central section may have a lattice structure through which bone graft may flow to promote bone ingrowth. A solid core region may be located inwards from the lattice structure. The central section may also have openings through the core region to connect the lattice structure to the cannula.

Disclosed is an expandable interbody fusion implant that is configured to have an initial configuration having a first footprint width suitable for being inserted into an intervertebral space and an expanded configuration having a second footprint width that is greater than the first footprint width. The implant may include a first body member and a second body member that is pivotally coupled to the first body member. The implant may be expanded using an inflatable balloon. The implant may be expanded bilaterally such that both body members rotate relative to the other or the implant may be expanded unilaterally such that one of the body members rotates relative to the other.

Biodegradable orthopedic implants and coatings for the implants are provided. The implant can include a Mg alloy and a coating, where the coating includes silk fibroin. The coating can be anticorrosive and can include a first layer comprising polydopamine and a second layer comprising silk fibroin. The silk fibroin can be combined with cellulose nanocrystals. Methods for making coated orthopedic implants are 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.
