Abstract: An arthroplasty plate and method of use to repair a fractured end of a bone are described. The arthroplasty plate comprises a fixation plate arranged to be secured to a surface of a bone and a connector assembly comprising a barrel extending from the fixation plate and having a bore which opens through the fixation plate. A connector rod is arranged to slide within the bore of the barrel. An articulation component comprises a bearing surface coupled to or arranged to couple to an end of the connector rod which extends from the barrel away from the fixation plate. The connector assembly incorporates an adjustment mechanism arranged to cause the connector rod to slide into or out of the barrel and a locking mechanism arranged to lock the position of the connector rod within the barrel to rigidly space the articulation component apart from the fixation plate.

Abstract: A satiation device is described which includes a sheath or liner extending from the proximal or middle stomach to the distal antrum. Food ingested by the patient passes through the sheath or liner, thereby minimizing contact between the ingested food and the stomach. It is believed that over time, reduced contact between food and the stomach will result in decreased Ghrelin production by the patient and a consequent decrease in appetite. In some embodiments, the satiation device may also include a proximal pouch and/or a distal bypass tube.

Abstract: A prosthetic system for use as a partial unicompartmental artificial knee replacement system. In one form, an artificial femoral bearing component is implanted along with a floating meniscus component that is configured to cooperate with the femoral bearing component to move through a plurality of translational and rotational positions as the knee rotates through a variety of angles. In another form, an artificial tibial bearing component is implanted along with a floating meniscus component that is configured to cooperate with the tibial bearing component to move through a plurality of translational and rotational positions as the knee rotates through a variety of angles.

Abstract: An orthopedic tibial prosthesis includes a tibial baseplate with an asymmetric periphery which promotes proper positioning and orientation on a resected tibia, while also facilitating enhanced kinematics, soft-tissue interaction, and long-term fixation of the complete knee prosthesis. The asymmetric baseplate periphery is sized and shaped to substantially match portions of the periphery of a typical resected proximal tibial surface, such that proper location and orientation is evident by resting the baseplate on the tibia. The baseplate periphery provides strategically positioned relief and/or clearance between the baseplate periphery and bone periphery, such as in the posterior-medial portion to prevent deep-flexion component impingement, and in the anterior-lateral portion to avoid undue interaction between the anatomic iliotibial band and prosthesis components.

Abstract: An accommodating intraocular lens construction includes a lens of fixed optical power to correct refractive error and a lens of variable power to restore accommodation of the eye, which variable lens can have two optical elements which either shift perpendicular to the optical axis, or which variable lens can have two elements which move along the optical axis. The accommodating intraocular lens has at least one haptic to provide transfer of movement to at least one of the optical elements and at least one additional haptic for sulcus fixation to provide limitation of movement of at least one component of the lens along the optical axis. The movement of the additional haptic is largely independent from the haptic for movement.

A proximal-posterior tip of the medial condyle is rounded and is shifted inwards relative to the native level of the proximal-posterior region of the femur bone to facilitate knee flexion. A method of mounting a femoral prosthesis on a femur is also described.
