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.

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 four-component artificial intervertebral disc may provide six degrees of movement: flexion, extension, lateral bending, axial rotation, axial deflection, and anterior/posterior translation. The disc may include a superior endplate, a superior core, an inferior core, and an inferior endplate. The superior endplate may include a concave mating surface, and the inferior endplate may include a spherical mating surface. The superior endplate may roll across the superior core to provide flexion, extension, and lateral bending. The superior endplate may twist or rotate atop the superior core to provide axial rotation, and the superior endplate may slide over the superior core to provide anterior/posterior translation. The superior core may be connected to the inferior core, and the inferior core may be connected to the inferior endplate. The inferior core may be made from a flexible material that may enable the artificial disc to expand or compress vertically.

Novel articles of manufacture based comprising lattices based on trabecular bone, having a plurality of plates and interconnecting rods. The trabecular bone-inspired lattice may be designed based on the general alignment of plates and rods found in trabecular bone, including anisotropic lattices having one or more predominant axes of mechanical strength. Lumbar fusion implants and other implants are provided having a trabecular bone inspired lattice in which bone graft material may be packed and providing a scaffold for bone fusion and growth. The implants may be based on bone structures having a predominant axis of mechanical strength and may be deployed in sites with the predominant axis of mechanical strength aligned with the primary axis of mechanical stress, such as in the the spine.

A fusion cage has a first component that defines an outside surface that is configured to engage a vertebral endplate, and an interior surface. The fusion cage has a second component that defines first and second opposed surfaces. One of the first and second opposed surfaces can mate with the interior surface of the first component. The fusion cage can include vertical and lateral throughholes adapted to enhance fusion.

A prosthesis system comprises plates that can be positioned against vertebrae and a selected resilient core that can be positioned between the plates to allow the plates to articulate. The selected resilient core can be chosen from a plurality of cores in response to patient characteristics, such as age and/or intervertebral mobility, such that the prosthesis implanted in the patient is tailored to the needs of the patient. The plurality of cores may comprise cores with different resiliencies, and one of the cores can be selected such that the upper and lower plates articulate with the desired shock absorbing resiliency and/or maximum angle of inclination when the one selected core is positioned between the plates.

A spacer for separating bones of a joint, the spacer includes a first endplate configured to engage a first bone of the joint; a second endplate configured to engage a second bone of the joint; tissue engaging projections, wherein the tissue engaging projections are moveable from a retracted position to a deployed position; and an actuation subassembly that extends between the first endplate and the second endplate, wherein the actuation subassembly comprise a drive nut, a drive screw coupled to the drive nut, and a cam frame coupled to the drive screw, wherein the cam frame is disposed between the first endplate and the second endplate to engage the tissue engaging projections.

A spinal implant includes a first member configured to penetrate tissue and a second member. The second member has an abutment engageable with a surgical instrument and at least one peripheral capture element engageable with a moveable arm of the surgical instrument. Systems, spinal constructs, surgical instruments and methods are disclosed.

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.

Artificial intervertebral discs include an annulus fibrosus portion and a nucleus pulposus portion. Annulus fibrosus portions disclosed and contemplated herein include a plurality of layers. Fibers within the layers are arranged to provide a crisscross pattern between adjacent layers. Nucleus pulposus portions disclosed and contemplated herein can include a flexible, sealed enclosure.
