A method for inserting an intervertebral disc prosthesis into a space between two vertebrae involves inserting the prosthesis partway into the space under constraint to prevent endplates of the prosthesis from articulating, releasing the prosthesis from constraint, and inserting the unconstrained prosthesis farther into the space. In some embodiments, the method involves grasping the prosthesis with a grasping device to insert the prosthesis partway under constraint, loosing the grasping device to release the prosthesis from constraint, and pushing the prosthesis farther into the disc space using the grasping device and/or one or more separate pusher devices. A system includes a grasping device, at least one separate pushing device, and optionally a vertebral spreading device and/or a vertebral midline indicator device.

A surgical plate system, components and methods of using are described. A surgical plate system includes a plate having an anterior surface, a posterior surface, a longitudinal axis, a transverse axis and a through hole passing through the anterior and posterior surfaces. A variable fastener is configured and dimensioned to connect to the plate, the variable fastener having a head and a shaft extending distally from the head. The head is configured to assume different proximal end diameters. The head, in a first configuration allows inward flexing to reduce a diameter of the head to allow the head to pass through an entrance opening of the through hole. In a second configuration, the head is prevented from flexing inwardly thereby preventing the head from backing out of the entrance opening, while allowing articulation of the head, within the through hole, relative to the plate.

An improved stud for assembling an engine valve cover or other mechanical parts together comprised of an elongated shaft having two end portions and at least one intermediate threaded portion therebetween. At least one end portion of the stud has a drive receiving recess formed therein. The intermediate threaded portion may be a single continuous thread or two distinct threads. The pitch and spacing on the thread or threads need not be identical and are ideally matched to the receiving threads of an orafice. The drive pocket in the head of the stud allows the shaft to be installed and removed by applying torque to the end and not to the body of the stud along the shaft. The stud may also be securely held so as not to be loosened or removed from one set of receiving threads into which it is installed while an object is installed or removed from the threads on the opposing end.

A modular barrier includes a plurality of substantially identical barrier sections each section having a base portion surmounted by an upright portion. The upright portion has projections with substantially semi-cylindrical outer surfaces at its ends. Correspondingly shaped recesses are also provided. At a femal end, the base portion includes a nose. The surface of the nose is a surface of rotation of the profile of the base portion. At the male end, the base portion includes a correspondingly shaped cavity. The first and second projections and the nose are provided with bores. When the female end of the barrier section is brought up to a male end of a similar, adjacent barrier section, the projections mate with one another and the nose is received in the cavity of the adjacent barrier section. A hinge pin may then be passed through the bores for allowing one barrier section to be articulated to an adjacent barrier section with the joint between the two portions of adjacent barrier sections presenting an essentially smooth profile irrespective of the angle between the two adjacent barrier sections.

A stuffed animal includes a body and an appendage attached to the body. The appendage includes an elongate bi-stable spring element movable between a first extended position that is straight and a second articulated position that forms a loop. The stuffed animal further includes a material covering the body appendage. Deflecting the surface of the bi-stable spring element, such as by lightly rapping it, causes the spring element to move to the second articulated position and wrap the appendage around an object, such as a wrist, a child's bed rail, or stroller bar. The stuffed animal hangs from the object by the appendage, and will stay attached until pulled off, thereby preventing the accidental loss of the animal.
