In various embodiments, an implant for interfacing with a bone structure includes a web structure including a space truss. The space truss includes two or more planar truss units having a plurality of struts joined at nodes and the web structure is configured to interface with human bone tissue. In some embodiments, a method is provided that includes accessing an intersomatic space and inserting an implant into the intersomatic space. The implant includes a web structure including a space truss. The space truss includes two or more planar truss units having a plurality of struts joined at nodes and the web structure is configured to interface with human bone tissue.

A device, for example a medical implant, and a method of making the same, the device having a metal or metal alloy substrate, for example cobalt chrome, and a diffusion hardened metallic surface, for example a plasma carburized surface, contacting a non-diffusion hardened surface or a diffusion hardened surface having a diffusion hardening species different from that of the opposing surface.

A composition and medical implant made therefrom, the composition including a thick diffusion hardened zone, and preferably further including a ceramic layer. Also provided are orthopedic implants made from the composition, methods of making the composition, and methods of making orthopedic implants from the composition.

An orthopaedic implant having a bone-engaging layer configured to contact bone and provide antimicrobial properties and methods for making the same.

Compositions including a surface or film comprising nanofibers, nanotubes or microwells comprising a bioactive agent for elution to the surrounding tissue upon placement of the composition in a subject are disclosed. The compositions are useful in medical implants and methods of treating a patient in need of an implant, including orthopedic implants, dental implants, cardiovascular implants, neurological implants, neurovascular implants, gastrointestinal implants, muscular implants, and ocular implants.

A distal portion of a filament is extended beyond the distal end of a needle containing a gripper. A flexible one-way filament retainer with a snagging point is positioned adjacent to the extended filament. The needle with the extended filament and the one-way filament retainer are inserted into a cannula. During partial withdrawal of the needle, the snagging point of the one-way filament retainer hooks or retains the distal portion of the filament, depositing a section of the filament between the snagging point of the one-way filament retainer and the needle. When the needle is re-advanced, the needle pushes open the flexible one-way filament retainer, and the section of the filament is expelled or deposited in tissue. The needle can be rotated; the gripper engages and spirals the expelled filament to burrow into tissue. The method of needle partial withdrawal, re-advancement, rotation and pushing is repeated to pack and fill the tissue with interconnecting spirals of filament.

Implantable devices that comprise an improved bone graft material, such as for example, bioactive glass, are disclosed. Additionally, implantable devices that work in conjunction with an improved bone graft material and act as a composite implantable device, for the improved treatment of bone, are also disclosed. These devices are bioactive, and are engineered to provide enhanced cellular activity to promote bone fusion or regrowth.

Various embodiments of implant systems and related apparatus, and methods of operating the same are described herein. In various embodiments, an implant for interfacing with a bone structure includes a web structure, including a space truss, configured to interface with human bone tissue. The space truss includes two or more planar truss units having a plurality of struts joined at nodes. Implants are optimized for the expected stress applied at the bone structure site.

Methods for altering the natural history of degenerative disc disease and osteoarthritis of the spine are proposed. The methods focus on the prevention, or delayed onset or progression of, subchondral defects such as bone marrow edema or bone marrow lesion, and subchondral treatment to prevent the progression of osteoarthritis or degenerative disc disease in the spine and thereby treat pain.
