Abstract: A device for providing support for a user seated on a commode and comprising a substantially U-shaped framework attached to a wall behind the commode includes a pair of elongated horizontal members joined by a crossbar and having legs at its forward corners. The framework is rotated through substantially 90.degree. to rest with its legs on the floor in front of the commode. A padded tray is slidably mounted on and rotatable with the horizontal members of the framework and is moved closely adjacent to the user when the user is seated on the commode. When not in use, the device is rotated upward, folded against the wall, and secured to the wall by a clip. The device is preferably made of polyvinyl chloride pipe and the tray is covered with a sheet of plastic material.

Abstract: A synthetic intervertebral disc prosthesis, molded in the same shape and general dimensions as a natural disc which it replaces after removal of a damaged natural disc, is molded of a biologically acceptable, non-porous, preferably rubber or silicone-rubber compound in two halves, each half having a hollow, molded interior. The two halves are joined together with a non-toxic adhesive to form a body having a fluid-tight cavity in its interior. The upper and lower surfaces of the disc each have a plurality of small suction cup-like projections molded thereon for frictionally engaging adjacent vertebrae. After the two halves of the prosthesis are joined, the prosthesis is implanted between two vertebrae in place of a removed natural disc, and a volume of fluid, such as saline solution, is injected into the interior cavity of the prosthesis to create the necessary amount of resilliency which restores proper vertebral spacing and facilitates flexibility of the spinal column.
