An improved spinal intervertebral prosthetic device that offers all degrees of motion afforded by the anatomic spinal intervertebral disc, and by virtue of the incorporation of a dashpot assembly mechanism within reversibly displaceable bellows, provides hydraulic load bearing capability as well as limiting the maximum pressure that can be exerted on the bellows assembly by limiting the compression stroke of the device. The dashpot assembly also increases resistance to lateral shear loading in excess of the bellows convolutions acting alone. The spinal intervertebral prosthetic device absorbs varying axial loads via hydraulic pressure transfer to the bellows convolutions which can flex in a spring-like fashion. Rotational coupling of the upper crown plate and center bearings plate permits normal twisting movements, and spinal flexural freedom is provided by the bellows that are interposed between the center bearings plate and the lower crown plate.

A peripheral stent with individual segments reduces the occurrence of fatigue fracture failure seen in vessels and tubes having bending and twisting movement. Segments can be attached via connecting fibers that biodegrade and offer the segments freedom of movement. The segments are balloon-expandable but will not be crushed by external forces placed upon the stent. Hinges and struts provide the stent with a plastic deformation during expansion and remain elastic if exposed to an oval shape. The segments overlap each other to provide improved scaffolding of the vessel wall and a greater flexibility during delivery. A composite stent having both balloon-expandable and self-expanding character has application in the venous system.

A suction cup device includes a cup forming unit cooperating with a flat surface to create a volume-variable space, a liftable rod secured to a central portion of the cup forming unit, a bracing shell member having a force-transmitting surrounding wall in engagement with a peripheral portion of the cup forming unit, and a twistable cap member having a surrounding bottom wall in abutting against a circumferential abutment region of the bracing shell member and threadedly engaged with the liftable rod such that a manually twisted movement of the twistable cap member can result in axial movement of the rod so as to pull the central portion away from the flat surface to produce a reduced pressure in the volume-variable space and a biasing force to thereby ensuring fluid-tight engagement of the cup forming unit with the flat surface.

The invention is an improved yo-yo that features two side assemblies that sandwich a center axle onto which the yo-yo's tether may be secured. According to a first embodiment, each of the side assemblies preferably includes a releasable, disk-shaped rim piece. By replacing one set of replaceable rim pieces with another, a user can quickly and easily change the yo-yo's shape, look and/or functionality. To remove a rim piece, one first removes a lock ring that is secured to the rim piece and blocks a number of openings that lead to grooves in a center-located hub. Next, one employs a twisting movement of the rim piece to cause a number of tabs attached to the rim piece to slide in the hub's grooves until the tabs are aligned with the openings. The rim piece can then be disengaged from the yo-yo.
