Abstract: A flexible, polymer sleeve is provided that is everted into a body passageway in such a manner as to exert minimal rubbing friction on the internal walls of such passageway. The sleeve is housed within a tube assembly comprising a posterior tube that telescopingly slides into an insertion tube. The sleeve everts over the insertion tube, upon forward pressure applied thereon, as it extends forward into a body passageway, and consequently, causes the posterior tube to retract into the insertion tube. Multiple tubes can be telescoped to support the polymer sleeve and to keep a passageway open for the expelling of urine or body fluids, the insertion of tools, sanitation/antibacterial substances, or for the flow of liquids through the sleeve. The insertion tube can be locked in reference to the sleeve to prevent unintended removal of catheter assembly. Sleeve and tubing are removed by reversing the insertion and eversion movements.

Abstract: A centralizer for centralizing a pipe is provided which collaborates the spring force of its bow springs. The centralizer includes a pair of end collars, and at least one center collar. Each of the collars has a center hole for coaxially receiving a pipe. In addition, the centralizer includes a plurality of longitudinally extending and arcuate bow springs having ends which affix to the end collars. The centralizer includes linkage arms which connect the center collar to the bow springs. The linkage arms may provide additional outward spring force against the bow springs. Preferably, the centralizer includes a mechanism for forcing the bow springs radially inward from their at rest position.

Abstract: The system provides a removable sun screen that can provide shade and/or UV protection for strollers, car seats, and other carriers for infants and toddlers. The device has adjustable fastening means that allow it to be used with a plurality of carriers. The device includes at least four deformable and semi-rigid fastening mechanisms that are pivotally mounted to a screen member. The pivotal mounting allows the fastening mechanisms to be repositioned as desired, allowing the device to have more universal application to a multiple of carriers. The device includes two top straps that are also bendable and can be pivoted to aid in affixing the screen member to a carrier.
