Apparatus and associated methods relate to a balloon kyphoplasty surgical device comprising an extrusion tube having internal fluid channels and a support wire, a port arrangement positioned on a proximal end of the extrusion tube and a balloon arrangement positioned on a distal end of the extrusion tube, the balloon arrangement resulting in a cubic shape when inflated by the port arrangement. An exemplary implementation may be configured with multiple inner balloons housed in an outer balloon to create a specific shape. Some designs may be configured with multiple ports designed to individually and independently inflate each inner balloon and outer balloon. The outer balloon may be inflatable. The outer balloon may be sealed off, constraining inflation of the inner balloons to create a cubic-like shape when the inner balloons are inflated within the sealed outer balloon, resulting in improved vertebral structure stabilization by increased surface area lifting the bone.

A synthetic tissue-graft scaffold (10) includes one or more nominally identical scaffold cages (12) that are configured to facilitate regrowth of tissue of an organism in and around the scaffold cages. Each scaffold cage comprises a volumetric enclosure (14) bounded by a perforated wall structure (30) that has an interior surface (32) and an exterior surface (34). A first annular inlet (22) and second annular inlet (24) positioned at opposite ends of the enclosure form, respectively, a first conjoining surface (54) and a second conjoining surface (56) that are configured so that confronting conjoining surfaces form complementary surfaces to each other. A perforated platform (60) is bounded by the interior surface of the enclosure and provides passageways (62) within the interior chamber. Corridors (40) extend through the perforated wall structure and communicate with the passageways to enable migration of material within and out of the cage.

A method of manufacturing an implant, including mixing a first quantity of biocompatible polymer particles, a second quantity of bioactive ceramic particles, and a third quantity of fugitive material particles to define an admixture, forming the admixture to define a composite body having an inferior portion, a superior portion and a central portion disposed between the inferior and superior portions, heating the admixture to fuse the first quantity of bioactive polymer particles to define a composite implant body, and infiltrating the composite implant body with a solvent to remove fugitive material particles to yield a network of interconnected pores and to define a porous implant body. The fugitive material particles are hollow spheres partially filled with a material selected from the group comprising air, bioactive agents, biological growth enhancers, drugs, and biocompatible polymer material, combinations thereof.

An implant holder is provided with a first guide lumen and second guide lumen. The implant holder has a first position wherein the implant holder couples to an interbody implant, aligns the first guide lumen with a first hole in the interbody implant, and aligns the second guide lumen with a second hole in the interbody implant. The implant holder has a second position wherein the implant holder releases the interbody implant.

Methods and apparatus for providing correction of one or more maladies or conditions of the spinal column of a living being. In one embodiment, the apparatus includes an implant delivery instrument and an implant for use therewith. In one variant, the implant delivery instrument includes a non-detachable distraction member for distraction of the disc space and a track for slidable delivery of an implant to the distracted disc space. In another variant, the implant delivery instrument includes a detachable distraction member for distraction of the disc space and a track for slidable delivery of an implant to the distracted disc space. In the latter variant, the distraction member is co-implanted in the disc space with the implant.

Spinal interbody cages are provided that include a bulk interbody cage, a top face, a bottom face, a top mesh structure, a bottom mesh structure, pillars, and slots. The top and bottom faces are exterior surfaces of the bulk interbody cage having a top central opening and a bottom central opening, respectively. The top and bottom mesh structures extend from the bulk interbody cage across the top central opening and the bottom central opening, respectively. The pillars are for contacting vertebral bodies. The slots are to be occupied by bone of the vertebral bodies and/or by bone of a bone graft. The spinal interbody cage has a Young's modulus of elasticity of at least 3 GPa, and has a ratio of the sum of (i) the volumes of the slots to (ii) the sum of the volumes of the pillars and the volumes of the slots of 0.40:1 to 0.90:1.

Osteoconductive devices and methods of use are provided herein. An example device includes a hollow body member having surfaces, the hollow body member having a shape that substantially conforms to a cross-sectional area of an opening of an orthopedic prosthesis, and apertures formed in the surfaces of the hollow body member that provide a osteoconductive path through the hollow body member.

A balloon kyphoplasty surgical device including an extrusion tube having internal fluid channels and a support wire, a port arrangement positioned on a proximal end of the extrusion tube and a balloon arrangement positioned on a distal end of the extrusion tube, the balloon arrangement resulting in a cubic shape when inflated by the port arrangement.

A modular synthetic tissue-graft scaffold (10) includes one or more nominally identical scaffold cages (12) configured to facilitate regrowth of tissue of an organism in and around the scaffold cages. Each scaffold cage comprises a volumetric enclosure (18) bounded by a perforated wall structure (40). A recess (24) formed at one end of the volumetric enclosure defines an inner stepped coupling surface. An annular raised portion (26) positioned at the other end of the volumetric enclosure forms an outwardly projecting stepped seating surface sized to form a complementary matable surface to the inner stepped coupling surface for whenever an inner stepped coupling surface of another one of the cages is placed on the outer stepped seating surface of the scaffold cage. Corridors (46) extending through the perforated wall structure and communicating with passageways (54) within the volumetric enclosure enable migration of material within and out of the scaffold cage.
