Abstract: A deflectable catheter comprises a catheter body, a tip section and a control handle. The Control handle, which is preferably curved, comprises a housing having a generally hollow interior, a piston receiving assembly at least partially within the interior of the housing, and a piston. The piston receiving assembly is afforded rotational movement but not longitudinal movement relative to the housing and comprises a generally tubular member defining a piston chamber. The piston is fixedly attached to the proximal end of the catheter body and extends into the piston chamber of the piston receiving assembly, wherein the piston is afforded longitudinal movement but not rotational movement relative to the piston receiving assembly. Rotation of the piston relative to the housing correspondingly rotates the piston receiving assembly, catheter body and tip section. A puller wire extends from the control handle, through a lumen in the catheter body and into a lumen in the tip section.

Abstract: A multipositioning power mobility aid for physically challenged children is provided. The power mobility aid provides a transition to a power wheelchair. The power mobility aid includes a multipositioning main frame that allows a child to be placed in a sitting, semi-standing or standing position without requiring multiple adjustments. The back support rotates to a nonsupporting position to facilitate placing a child in or removing a child from the power mobility aid. The back support then locks into an upright supporting position after the child is positioned in the power mobility aid. The power mobility aid includes an adjustable arm that supports the user-operable input device in multiple locations.

Abstract: Expansion joint cover assemblies are disclosed which are structured and dimensioned for use in covering expansion joints or spaces between adjacent structural sections of a building such as spaced floors or floor and wall sections. The assemblies include base members adapted to be positioned and secured to the adjacent structural sections and a leaf spring cover member fixedly interconnected to one of the base members at one end and bridging the expansion joint or space between the structural sections in a cantilever manner such that the cover member lies in a plane essentially flush with the floor section or sections and is structured and dimensioned to be slidably interconnected with the other base member to provide a secure, functionally effective and aesthetically pleasing assembly for accommodating translational relative movement of the structural sections.
