POROUS COMPOSITE BIOMATERIALS AND RELATED METHODS
A composite material for use, for example, as an orthopedic implant, that includes a porous reinforced composite scaffold that includes a polymer, reinforcement particles distributed throughout the polymer, and a substantially continuously interconnected plurality of pores that are distributed throughout the polymer, each of the pores in the plurality of pores defined by voids interconnected by struts, each pore void having a size within a range from about 10 to 500 μm. The porous reinforced composite scaffold has a scaffold volume that includes a material volume defined by the polymer and the reinforcement particles, and a pore volume defined by the plurality of pores. The reinforcement particles are both embedded within the polymer and exposed on the struts within the pore voids. The polymer may be a polyaryletherketone polymer and the reinforcement particles may be anisometric calcium phosphate particles.
Demineralized bone fiber composition for use in minimally invasive surgery
A bone implant composition and methods thereof include bone material made into various implant shapes including a cylinder having an outermost layer and an inner layer completely surrounded by the outermost layer. The bone implant compositions and methods include a bag or cylindrical tube made from a bone material which may be filled with additional bone material.
Porous composite biomaterials and related methods
Synthetic composite materials for use, for example, as orthopedic implants are described herein. In one example, a composite material for use as a scaffold includes a thermoplastic polymer forming a porous matrix that has continuous porosity and a plurality of pores. The porosity and the size of the pores are selectively formed during synthesis of the composite material. The example composite material also includes a plurality of a anisometric calcium phosphate particles integrally formed, embedded in, or exposed on a surface of the porous matrix. The calcium phosphate particles provide one or more of reinforcement, bioactivity, or bioresorption.

IMPLANTABLE DEVICES
Implantable devices for orthopedic, including spine and other uses are formed of porous reinforced polymer scaffolds. Scaffolds include a thermoplastic polymer forming a porous matrix that has continuously interconnected pores. The porosity and the size of the pores within the scaffold are selectively formed during synthesis of the composite material, and the composite material includes a plurality of reinforcement particles integrally formed within and embedded in the matrix and exposed on the pore surfaces. The reinforcement particles provide one or more of reinforcement, bioactivity, or bioresorption.
Artificial intervertebral implant
An intervertebral implant includes a core member operably coupled between an upper and a lower base member. An outer cavity extends between the core member upper end and lower end, and radially between the inner cavity and an outer surface of the core member. A core member inner wall is formed between the inner and an outer cavity, and a core member outer wall is formed between the outer cavity and the outer surface of the core member. A first locking member is positioned on at least one of the core member upper end and the core member lower end and at least one second locking member is positioned on an inner surface of at least one of the upper and lower base member for locking engagement. The upper and lower end of the core member are oriented at a lordotic angle ranging from 1 degrees to 20 degrees.
DEMINERALIZED BONE FIBER COMPOSITION FOR USE IN MINIMALLY INVASIVE SURGERY

The bone implant compositions and methods include a bag or cylindrical tube made from a bone material which may be filled with additional bone material.
METHOD AND IMPLANT DEVICE FOR GRAFTING ADJACENT VERTEBRAL BODIES
A methodology for grafting together adjacent bony structures is provided using an implant device having an endplate with an inner disc portion and outer ring portion spaced from the inner disc portion by a connecting wall disposed there between. An endplate interior surface includes a retaining structure for securing the endplate to one of the bony structures, and endplate an exterior surface has an integrally formed socket. A ball-joint rod has a longitudinally extending body and an end, and at least a portion of the ball-joint rod end is curvilinear in shape. The curvilinear ball-joint rod end is rotatably disposed in the endplate socket to fixedly interconnect the bony structures.
IMPLANT FOR THE INTERVERTEBRAL DISC SPACE FOR TREATING SCOLIOSIS, KYPHOSIS, STENOSIS AND FRACTURES OF THE SPINAL COLUMN
Disclosed is an implant for the intervertebral disc space, for the treatment of scoliosis, kyphosis, stenosis and fractures of the spinal column, which comprises a substantially cylindrical, inflatable, flexible, biocompatible element that has a morphology dependent on the problem to be treated and is suitable for insertion into the intervertebral disc space. The implant can be inflated using an external pressure system in order to allow the injured disc to be lifted, and it can be filled with a material (2) which, once solidified, has an elastic hardness similar to that of a healthy intervertebral disc at the vertebral level in which the implant is to be inserted, said elastic hardness being higher in the area of the lumbar vertebrae and lower in the dorsal or cervical area.
Artificial disc
A medical device includes a base ring configured to be implanted within a body of a patient. The base ring provides a contact surface to a vertebra. Multiple layers of multiple leveling plates are configured to equalize forces applied to the contact surface of the base ring, where at least one of the layers of the leveling plates engages an inner surface of the base ring. A layer of multiple pads is included with a top surface of the pads configured to maintain a parallel plane and a bottom surface of each of the multiple pads is configured to engage a top surface of one of the layers of the leveling plates. A cover is configured to enclose the multiple layers of the leveling plates, the layer of the multiple pads and the base ring. The cover provides a contact surface to a vertebra.
