摘要:
A seating unit is provided with a detachable bezel that is selectively engaged and disengaged to a receiving module. The receiving module is assembled to an interior of the seating unit and operably coupled to the activation device (e.g., linear actuator for adjusting the position of the seating unit). In operation, the receiving module is configured to receive command signals via a communication interface between the receiving module and the detachable bezel. Typically, an intermediate material of the seating unit intersects the communication interface. Further, the receiving module is configured to invoke the activation device as a function of the command signals. The detachable bezel resides external to the seating unit and is freely wielded by a user upon being disengaged from the receiving module. Additionally, the detachable bezel includes touch-activated controls that, upon receiving user-initiated actuation, generate the command signals via the communication interface.
摘要:
A femoral knee implant includes a fourth compartment of articulation. The superior posterior articulating surface is achieved by first increasing the thickness of the superior posterior condylar portion of the femoral component to widen the superior posterior edge of the posterior condyle. Second, the newly created surface at the superior posterior condyle is smoothly rounded to provide an articular surface with no sharp changes in the surface contours. In one embodiment, the fourth articular compartment of this invention is provided in a one piece femoral design. In another embodiment, it is provided as a modular addition to an existing prior art femoral component. In another embodiment, the fourth compartment is combined with a posterior stabilized (PS) TKR design that includes a tibial post and cooperating femoral cam characterized by low engagement of the cam on the spine.

The present invention includes methods and materials for manipulating the sense of satiety developed from the gastrointestinal transit of a substance in a mammal, whether the substance be a food or drug compound. The method involves administering a therapeutically effective amount, by a direct delivery route, of a pharmaceutically acceptable formulation comprising nutrients and pharmacological agents to the mammal's gastrointestinal tract. The present system is designed to maximize satiety feedback from normal intestinal sensors by small amounts of nutrients or nutrient derivatives, in essence, to “fool” body sensors that are not usually in contact with nutrients unless very large amounts are ingested.

摘要:
A method of manufacturing an articulating bearing surface for use in an orthopaedic implant uses a supply of ultra-high molecular weight polyethylene particles which are irradiated with sufficient radiation energy to crosslink at least a portion of the ultra-high molecular weight polyethylene. The irradiated particles are then formed into an orthopaedic bearing surface.

An instrument 2 used to install both the outer shell 40 and bearing liner 50 of a conventional acetabular cup assembly 4. Instrument 2 includes an impactor 30 and a reversible cup or head component 10, which is adapted for driving shell 40 into the acetabulum and for seating bearing liner 50 into the shell. Head component 10 has a rounded semi-spherical surface 12 on one end and a substantially flat surface 14 on the opposite end. Impactor 30 includes a longitudinal extension 36 which can be inserted into a bore 20 in head component 10 from either direction to secure the head component to the impactor. When instrument 2 is used to seat shell 40 into the acetabulum, head component 10 is fitted to impactor 30 with semi-spherical surface 12 facing outward for abutment against inner surface 44 of shell 40. Shell 40 is connected to the distal end 39 of extension 36, which protrudes from semi-spherical surface 12 of head component 10. When instrument 2 is used to seat bearing liner 50 into shell 40, head component 10 is connected to impactor 30 with flat surface 14 facing outward for abutment against bearing liner 50.

An adjustable bed is provided having a mattress, a mattress support, and an attachment panel for removably attaching the mattress to the mattress support. The attachment panel can be disposed along at least a portion of at least one side of the mattress and extends below a bottom surface of the mattress. The attachment panel is attached to an underside of the mattress support.

摘要:
The metal lock ring of the invention has an oblong exterior periphery which allows the ring to have a small "width" and a larger "height." The small "width" provides a strong locking mechanism on the poly liner and the larger "height" allows the ring to remain secure within the groove of the metal shell prior to and during assembly of the polyethylene liner. The ring has a chamfer on its inside leading edges defining its width to facilitate assembly of the liner. This optimizes the ease of assembly and is simpler and more economically to produce than a chamfer all the way around the oblong ring. In the preferred embodiment, the lock ring has a constant thickness such that the inner periphery and the outer periphery are oval.In an alternative embodiment, the metal lock ring has a round inner diameter and a round outer diameter that are not concentric, thereby creating a thickening of the ring at one end. The shape of the alternative lock ring provides for substantial contact between the lock ring and the poly liner about the liner. The thickened area of the ring retains the ring within the metal cup prior to and during assembly of the poly liner. The thickened portion of the ring may have scallops or notches formed therein to increase the flexibility of the ring.
