Disclosed are devices, system and methods for spinal implants to be deployed into an intervertebral space between adjacent vertebrae to replace the function of the intervertebral disc and the facets, while restoring stability, flexibility, coronal alignment/balance, sagittal alignment/balance and proper biomechanical motion.

The invention relates to bioactive surface coatings deposited on selected substrates. Surface nanostructured film coatings deposited on most metal or nonmetal substrates to provide surfaces can be engineered to promote enhanced tissue/cell adhesion. Attached cells, including osteoblasts, fibroblasts and endothelial cells, retain viability and will readily differentiate and proliferate under appropriate conditions. Fibroblasts and endothelial cells exhibit good attachment and growth on most coated substrates, except on nano surfaced structured silicone.

Medical devices and method for making and using the same are disclosed. An example medical device may include implantable medical device for use along the biliary and/or pancreatic tract. The implantable medical device may include a tubular member having a first end configured to be disposed within the duodenum of a patient and a second end configured to be disposed adjacent to a pancreatic duct and/or bile duct. The tubular member may have a body including one or more wire filaments that are woven together. The tubular member may also have an outer surface with a longitudinal channel formed therein.

A unitary intervertebral device, having no moving components is provided for non-fusion articulation and fusion applications. The interbody articulating device allows for limited flexion and rotation between the implant and an adjacent vertebrae, helping to preserve or restore near-normal motion between adjacent vertebrae. Rotational motion is achieved through one or more protrusions incorporated into the spinal interbody device. In one articulating form, a first protrusion extends perpendicularly from one bearing surface of the interbody device to form a rotational protrusion, while at least a second protrusion extends from the opposite bearing surface of the interbody device to form a non-rotational protrusion. In another form, a single protrusion extends axially from one bearing surface of the interbody device to form a spike or anchoring, rotating protrusion, while the opposite bearing surface may be slightly rounded and/or comprising a bone-ingrowth promoting surface. Similarly configured fusion salvage devices are also described.

An apparatus and methods are provided for a tapered implant for treating osteochondral defects. The tapered implant comprises a top portion that includes a shape that approximates an osteochondral surface to be replaced. A bottom portion of the tapered implant is configured to be implanted into a hole drilled in bone. A cylindrical sidewall of the tapered implant has a diameter that decreases from a first diameter of the top portion to a second diameter of the bottom portion. The tapered implant comprises any monophasic synthetic material suitable for implantation into bone, including any of silicone, bioglass, peek, polyethylene, titanium, and cobalt chrome.

A surgical implant having a surface treatment which contains primary cavities and secondary cavities. The primary cavities are larger than the secondary cavities and the primary cavities have an average length ranging from 20-500 micrometers. The surface treatment includes recasted material adjacent to a plurality of the primary cavities.

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

A line of joint implant systems includes an implant including a cup to be affixed in one of the elements of the considered joint, defining a smooth inner cavity of substantially hemispherical shape. The implant also includes an insert, mobile within the inner cavity of the fixation cup and having its smooth outer surface intended to cooperate by ball-and-socket joint with the inner cavity, and defining in turn a smooth inner cavity of substantially hemispherical shape. The implant further includes a head or ball, solid with a second element of the joint, of spherical shape, intended to be received in the inner cavity of the mobile insert and to form a second ball-and-socket joint. The ratio of the inner diameter of the inner cavity of the fixation cup to the inner diameter of the inner cavity of the mobile insert is constant, whatever the diameter of the selected ball.

A prosthesis may have an articulating component formed via casting and a 3D printed bone anchoring component with a joint-facing side and a bone-facing side. The bone-facing side may have a bone engagement surface with a porous structure with pores selected to facilitate in-growth of the bone into the pores. The bone facing side may further have a surface layer of Titanium Dioxide nanotubes. The joint-facing side may be secured to the articulating component by melting Titanium nanoparticles at a temperature below the melting temperatures of the major constituents of the articulating component and/or the bone anchoring component, such as Cobalt, Chromium, and/or Titanium, so as to avoid significantly modifying the crystalline structures of the articulating component and/or the bone anchoring component. The melting temperature of the Titanium nanoparticles may be about 500 C.

An orthopaedic knee prosthesis includes a femoral component which exhibits enhanced articular features, minimizes removal of healthy bone stock from the distal femur, and minimizes the impact of the prosthesis on adjacent soft tissues of the knee.
