A prosthetic device for replacing at least part of one vertebral body, the prosthetic device being expandable from a fully collapsed state to a fully expanded state and comprising an upper endplate, a lower endplate and an expandable support structure extending between the two endplates, said expandable support structure being configured to displace the two endplates relative to one another along a longitudinal axis of the prosthetic device and to hold the two endplates at a minimum axial distance that corresponds to the height of at least one intervertebral disc and half a vertebral body, wherein the expandable support structure includes an anterior post and a posterior post, wherein the length (L1/L2) of each post is individually adjustable and is lockable independently from one another to hold the two endplates with an inclination of 0 to 40 relative to each other.

A method for fusing spinal bone is provided. The method comprises placing a sac between two or more adjacent sections of the spine to be fused, inserting a cage into the sac, and filling the sac with bone tissue. The surfaces of the sac abutting the sections of the spine comprise porous material for allowing bone to grow between the spine and the sac. Surfaces of the sac not abutting the sections of the spine are nonporous to bodily fluids and thereby prevent premature deterioration of the bone tissue inside the sac. The cage maintains the sac in an expanded state upon filling. A kit comprising the sac and cage is also provided. In other embodiments of the invention, the method comprises placing an inner sac inside the inventive sac and filling the sacs with bone tissue for fusion of spinal bone.

An implant for use in a medical procedure includes an anchor body and a flexible material. The anchor body includes a perimeter sidewall having an upper free edge, an outer surface, and an inner surface. The anchor body also includes a bottom wall, connecting the sidewall on one edge, which has an inner surface and an outer surface. The inner surfaces of the sidewall and bottom wall define a cavity and the upper free edge of the sidewall defines a top opening into the cavity. The flexible material is connected to the anchor body and is positioned in the cavity with at least a portion extending out of the top opening.

A method for use of a double-structured tissue implant or a secondary scaffold stand-alone implant for treatment of tissue defects. The double-structured tissue implant comprising a primary scaffold and a secondary scaffold consisting of a soluble collagen solution in combination with a non-ionic surfactant generated and positioned within the primary scaffold. A method of use of a stand-alone secondary scaffold implant or unit for treatment of tissue defects.

The present invention is directed to a unique technology for preparing a growth-factor free, cylindrical, hydrogel implant that has multiple (three or more) longitudinal hydrogel zones with varying chemical and physical properties. The implant may be wholly made of hydrogels or the hydrogels may be associated with cells, such as mesenchymal stem cells (MSCs).

An implant device used to replace and restore the function of the knee meniscus in a human. The compliant, yet resilient device is comprised of a biocompatible, non-degradable three-dimensional body comprised of at least a central body, a second structure, a third structure, and a coating. The device is concentrically aligned wherein the second structure is adjoined to the central body wherein the third structure is adjoined on the central body opposite of the second structure. The third structure further features a first and a second pulling element which is coupled to the central body and forms the outer periphery and major circumference of the device. The device is comprised of multiple components which provide tensile strength, compressive resilience, and attachment mechanisms for replacing the meniscus. Each structure is comprised of multiple surfaces which are further reinforced, separated, and connected by an individual plurality of vertical elements. The implantable device further features a surface coating on the surface of the central body.

An implant system includes a fixation device that, in turn can include an expandable implant alone or in combination with an auxiliary implant. The expandable implant includes an expandable implant body that is made from an expandable material. The expandable material includes a polymer matrix and an expandable gas source contained within at least a portion of the polymer matrix. The implant system can further include an energy source configured to heat the polymer matrix to a temperature above its glass transition temperature, thereby causing the gas source to expand inside the polymer matrix. The fixation device can further include an insertion instrument configured to implant the fixation device into an anatomical cavity.

An implant system includes a first portion, a second portion, and a third portion. The first portion includes a hydrogel. The second portion includes a porous material and the hydrogel in pores of the porous material. The third portion includes the porous material. The first portion is free of the porous material. The third portion is free of the hydrogel. Methods of making and using the implant system.

An apparatus and method is provided for interbody fusion including distracting, in a given direction, and supporting opposing vertebral bodies. A plurality of wafers are consecutively inserted between the vertebral bodies to create a column of wafers. The column of wafers is oriented between the vertebral bodies so as to expand in the given direction as the wafers are consecutively added to the column.

An osteoimplant is provided which comprises a coherent aggregate of elongate bone particles, the osteoimplant possessing predetermined dimensions and shape. The osteoimplant is highly absorbent and sponge-like in nature. Also provided herein are a method of fabricating the osteoimplant and a method of repairing and/or treating bone defects utilizing the osteoimplant.
