In a knee prosthesis, the condylar surfaces of a femoral component engage corresponding articular surfaces of a tibial component along prescribed tracks of predetermined curvature which enable relative rotation between the femoral component and the tibial component about a longitudinal axis during articulation of the knee prosthesis, and at least the condylar surfaces or the articular surfaces are flared in a direction away from corresponding articular surfaces or condylar surfaces along engaged posterior and anterior portions of the condylar surfaces and articular surfaces to provide an increased area of contact in deep flexion and in extended hyperextension for reducing contact stresses and concomitant wear while militating against unwanted distraction of the knee prosthesis. In addition, the radius of curvature of the condylar surfaces is reduced along posterior portions of the condylar surfaces to further avoid distraction of the knee prosthesis in deep flexion, thereby enabling deep flexion with greater ease and without excessive contact forces between the femoral component and the tibial component in deep flexion.

Systems and methods for a vehicle mounted articulator are described. A vehicle conveniently allows an articulator to be moved to various remote work sites. In one embodiment, the articulator can be mounted on a movable base, thereby increasing the flexibility of use and / or reach of the articulator. Such vehicle-mounted articulators can be subjected to various potentially damaging situations due to motion of the vehicle. Various features that allow safe operation of the vehicle and the articulator are disclosed.

Provided is a device for improving the posture of a patient comprising a garment and a pair of tension straps. The garment is configured to tightly envelope the patient's torso and the patient's upper arms. The garment has an inner surface, a front side and a back side. The front side includes a chest portion. The back side includes a back portion. The garment defines opposing shoulder portions and a waist portion. The tension straps are releaseably securable to the back portion in diagonal relation to one another. Each one of the tension straps has opposed free ends that extend upwardly from the back portion to the chest portion and downwardly to the waist portion. The device includes viscoelastic pads releaseably mounted on the inner surface of the garment generally opposite the free ends and are configured to restrict movement of the free ends relative to the patient's skin.

A posture improvement device provides neuromuscular stimulation or proprioceptive therapy using a combination of pressure, torque and angle simultaneously applied to a user in order to train body muscles for proper posture through muscle memory. The device comprises a garment designed to be worn by the user, which is preferably configured like a short-sleeved undershirt or T-shirt. The garment may be fabricated of a stretchable, yet taut material in order to provide the desirable form-fitting feature such that pressure may be readily applied to the surface of the skin for neuromuscular stimulation. This elastomeric material is also preferably breathable and / or which has moisture wicking capabilities.

A surgical apparatus for positioning within a tissue tract accessing an underlying body cavity is adapted to tissues having different thicknesses. The surgical apparatus is configured to have different lengths. In one embodiment, the surgical includes a seal anchor member having two ends, and one of which is adapted to fold resulting in a plurality of folded states. Each folded state corresponds to a different length of the seal anchor member. The seal anchor member includes a slot to facilitate transition within the plurality of folded states. The seal anchor member further includes an aperture and a pin configured to further facilitate transition within the plurality of folded states.

A spinal screw assembly providing an adjustable securement of a fixation rod across at least two vertebrae. The assembly includes a pedicle screw having a spherical head portion, a threaded shaft portion and a tool engagement surface in the head portion for use in driving the screw into a vertebrae. The head portion of the screw is positioned in a body member adjacent a curvilinear surface disposed about an aperture in the end of the body member such that the shaft portion of the screw extends therethrough and the curvilinear inner surface abuts and mates with the head portion of the screw so as to define a ball joint therewith. The body member additionally defines a pair of opposed parallel slots therein adapted to receive a portion of the fixation rod and a locking cap bears against the fixation rod to releasably secure the rod within the assembly.

Various uses and constructions for an open sided nozzle for a surface cleaning apparatus are provided. Alternate constructions for a surface cleaning head are also provided.

A universal joint to transmit force from a tool to a workpiece. A driver attachable to the tool has a spherical cavity. A plurality of inwardly facing protrusions is formed in the cavity. Each protrusion has a pair of conical sidewalls separated by an angled ramp. A driven socket has a sphere formed on one end. The sphere has a plurality of channels. The sphere is received in the spherical cavity in the driver and the protrusions in the cavity are received in the channels. The drive webs forming the channel engage the protrusions when the driver is angularly offset from the driven socket.

A device for providing therapeutic treatment to a body part such as a knee joint to promote healing of the body part, including a signal generator for generating a pulsed electromagnetic field to electromagnetic stimulators based upon a selected treatment mode, a controller for storing the treatment mode and communicating the treatment mode to the signal generator and stimulators, a heat source configured to provide thermal therapy to the body part, and a monitoring element for monitoring the electromagnetic field generated by the electromagnetic stimulators. The device may also include a telemetry component in communication with the monitor for remotely accessing the controller to modify the treatment mode. The device can also be disposable.

The present invention features a remote viewing device that is capable of improving its operation by removing slack in its control cables and / or by increasing the range of motion of its viewing head. In one embodiment, the method for improving the operation involves removing at least a portion of the slack in at least one control cable attached to a servo motor. The removal of at least a portion of the slack includes changing the position of a servo motor relative to a flexible tube termination block until a specified tension is encountered in at least one of the control cables. The method further includes determining first and second servo control signal values corresponding to no angular deflection and a specified deflection in a viewing head.
