Spinal tissue distraction devices
09788974 · 2017-10-17 · ·

Spinal tissue distraction devices that include a member which has a pre-deployed configuration for insertion between tissue layers and a deployed configuration in which the member, by change of configuration, forms a support structure for separating and supporting layers of spinal tissue.

Bone implant for enclosing bone material

A bone implant for enclosing bone material is provided. The bone implant comprises a mesh having an inner surface and an outer surface opposing the inner surface. The inner surface is configured to receive a bone material when the inner surface of the mesh is in an open configuration. A plurality of projections are disposed on or in at least a portion of the inner surface of the mesh. The plurality of projections extend from at least the portion of the inner surface of the mesh and are configured to engage a section of the inner surface of the mesh or a section of the outer surface of the mesh or both sections of the inner and outer surfaces of the mesh in a closed configuration so as to enclose the bone material. A tray, a kit and a method of making the bone implant are also provided.

Zirconium oxide-based composite material

A ceramic composite material and a method for producing same. The ceramic composite material has a ceramic matrix comprising zirconium oxide and at least one secondary phase dispersed therein. The matrix is composed of zirconium oxide as at least 51 vol.-% of composite material, and the secondary phase is in a proportion of 1 to 49 vol.-% of composite material, wherein 90 to 99% of the zirconium oxide is present in the tetragonal phase based on the total zirconium oxide portion. The tetragonal phase of the zirconium oxide is stabilized by at least one member selected from the group consisting of chemical stabilization and mechanical stabilization. The ceramic composite is damage-tolerant.

Resorbable interbody device

A spinal interbody device fabricated of fully resorbable bioactive glass materials is used to maintain the intervertebral spacing in a fusion of adjacent vertebrae. The spinal interbody device can include regions of porous material having various levels of bioactivity so that fusion through ingrowth of bone tissue can be provided while regions of the spinal interbody device can continue to maintain the intervertebral space.

09737415 · 2017-08-22 · ·

Techniques and systems for distracting a spinal disc space and supporting adjacent vertebrae are provided. Trial instruments are insertable into the disc space to determine a desired disc space height and to select a corresponding implant. Implants can be also be self-distracting and the implant providing the desired disc space height can be implanted in the spinal disc space.

Orthopaedic implant with porous structural member

A tool for use with an orthopaedic implant includes: a tubular assembly including a tubular passage having a first end and a second end, the first end including a means for attachment to an implant body; a plug; and a plunger coupled to the plug. The tubular passage is configured to receive, via the second end, a material agent and the plunger coupled to the plug. The plunger is configured to slide through the tubular passage for expelling the material agent from the tubular passage into a load bearing member via the at least one first opening. The plunger is configured to rotate within the tubular passage for coupling the plug with the first opening to seal the first opening against expulsion of the material agent from the load bearing member via the first opening.

Medical Implant Porous Scaffold Structure Having Low Modulus

A medical implant porous scaffold structure having low modulus, wherein said structure is formed by multiple basic units superposed sequentially along the three-dimensional directions in three-dimensional space, each of the basic units is composed of a quadrangular prism or hexagonal prism having central interconnected pores encircled by four or six side walls, each of the side walls is composed by a “X-type” frame structure formed by two crossed ribs, and the central interconnected pores of the adjacent basic units arranged along the axis direction of the quadrangular prism or the hexagonal prism are interconnected to each other. The structure could not only reduce the modulus of the implant, make the modulus of the implant and strength achieve an ideal match, improve the configuration of traditional metal implants to optimize the distribution of mechanical and weaken the stress shielding effect; but also has a regular interconnected pores structure which is conducive to bone tissue in-growth, and can increase mutual locking of bone tissue and implant and shorten the recovery time of patients.

SPINAL CAGE HAVING DEPLOYABLE MEMBER

A spinal cage with a wall extending in a longitudinal direction defining an interior space is disclosed. There is also provided a deployable element in movable relation to the spinal cage.

Injectable fibrin composition for bone augmentation

The present invention relates to a biodegradable injectable composition for bone augmentation comprising fibrin, a contrast agent and calcium salt-containing particles, as well as a method for bone augmentation in a patient suffering from a bone disorder comprising injecting said composition into a non-mineralized or hollow portion of said bone.
