An orthopedic implant apparatus, said apparatus comprising: a body, said body having a generally cylindrical shape, a flat bottom surface, and a top surface; at least one stem, said at least one stem connected to said bottom surface of said body; an articular component, said articular component having a bottom connecting side and a top bearing side; and a flexible component, said flexible component disposed between said body and said articular component, said flexible component attached to said top surface of said body and said bottom side of said articular component.

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 vertebra, 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.

The present invention relates to an apparatus and method for near-simultaneous and integrated delivery of bone graft material during the placement of surgical cages or other medical implants in a patient's spine. The integrated fusion cage and graft delivery device according to various embodiments delivers and disperses biologic material through a fusion cage to a disc space and, without withdrawal from the surgical site, may selectively detach the fusion cage for deposit to the same disc space. The integrated fusion cage and graft delivery device is formed such that a hollow tube and plunger selectively and controllably place bone graft material and a fusion cage in or adjacent to the bone graft receiving area. In one embodiment, the integrated fusion cage is an expandable integrated fusion cage.

A system for distracting uncinate joints of a cervical spine segment includes two tapered elements and an actuator configured to couple with the tapered elements and change distance between the tapered elements, to insert the tapered elements into the uncinate joints, respectively, from the intervertebral disc space of the cervical spine segment.

Medical device implants disclosed herein may include an interior space and at least one bone on-growth structure disposed within the interior space. The bone on-growth structure may include a root coupled to an interior surface of the implant, or to a mesh insert disposed within the interior space of the implant. The root may extend into the interior space of the implant toward another opposing interior surface of the implant. The bone on-growth structure may also include a plurality of branches coupled to the root via a plurality of junctions. The plurality of branches may each project at a plurality of different angles with respect to the root. In some embodiments, the plurality of branches may each terminate within the interior space of the implant. In other embodiments, one or more branches may contact opposing interior surfaces of the implant. The medical device implants may also include one or more channels to enhance bone growth within the medical device implants.

A device and method for manufacturing artificial solid bone by metal 3D printing technology comprises: a metal 3D printing technology is used and preferably with CoCr alloy and laser sintering to form a solid bone with a specific change in shape and density; a synchronous cutting operation performed on approximately 80% of the preferred surface of the solid bone while the metal 3D printer unit is printing the solid bone, to make the solid bone have the following surface roughness: Ry<12 m or less; and a synchronous polishing operation performed on at least one joint surface of the solid bone, to make the joint surface have the following surface roughness: Class A4=Ra0.063 m or less.

An artificial femoral ball head having a multilayer shell-core composite structure includes a spherical shell layer, a transition layer and an inner core. The inner core is made of a toughened ceramic, the spherical shell layer is made of a ceramic material, and the transition layer is made of a composite material comprising materials of the inner core and the spherical shell layer. The artificial femoral ball head is manufactured through sintering a green body of successively stacked layers of the spherical shell layer, the transition layer and the inner core, and the green body of successively stacked layers is obtained through a powder co-injection molding process. The spherical shell layer of the artificial femoral head has a high rigidness, corrosion-proof and wear-proof performance. The inner core of the artificial femoral head has a high toughness and shockresistant performance.

An implant (30) for a mammalian bone joint (3) for spacing a first bone (2) of the joint from a second bone (1) of the joint while allowing translational movement of the second bone in relation to the first bone is described. The implant comprises (a) a distal part (31) configured for intramedullary engagement with an end of the second bone, (b) a proximal part (34) having a platform (15) configured for non-engaging abutment of an end of the first bone and translational movement thereon, and (c) an articulating coupling (10, 16) provided between the distal and proximal ends allowing controlled articulation of the first and second bones. The bone-abutting platform is shaped to conform to and translate upon the end of the first bone. A kit for assembly to form the implant of the invention, and the use of the implant to treat osteoarthritis in a bone joint, are also described.
