Abstract: A coating composition for applying a very thin film coating to a substrate such as a polymeric film comprises a copolymer such as a block copolymer (BCP) that is compatible with the substrate, an alcohol solvent or solvents capable of dissolving the copolymer, a hydrolysed metal alkoxide precursor, a carboxylic acid stabiliser, and an active agent in an ionic, molecular, or small nanoparticle form. The active agent is configured to provide a functionality to the coating composition, selected from antimicrobial, antifungal, barrier, therapeutic, electrical, electronic, magnetic and optical. The composition is a sol comprising a continuous non-sedimentable/stable suspension of very small sized (of nano order) amorphous inorganic polymers in their oligomeric or polymeric state, and comprising the active agent dispersed in a hydrolysed metal alkoxide-BCP matrix.

Abstract: A hub assembly includes a retainer housing, a retaining member, a biasing element, and a restraining element. The retainer housing includes an axle bore configured to receive an axle and a pin sleeve. The pin sleeve includes a first end in fluid communication with the axle bore, a second end, and a conduit between the first end and the second end. The retaining member is in the conduit and is configured to operatively engage a groove in an axle. The biasing element is in the conduit and is configured to bias the retaining member towards the axle bore. The restraining element is configured to prevent the retaining member from exiting the second end of the pin sleeve at least prior to coupling the hub assembly to a wheel. A wheel assembly can include the hub assembly and a wheel.

Abstract: The present invention is directed to a system and method for percutaneous delivery of bone cement during a surgical procedure. The system of the present invention has a plunger assembly 100, comprising: a shaft having a first end, a middle section, and a second end, wherein the middle section is threaded; and a handle attached to the first end of the shaft. The system further comprises a dispenser hub assembly 200 around the shaft having a collar and a hand-grip attached to the collar, and a threaded portion formed on an interior surface of the collar. The system may further comprise a hollow tube 300 for containing the bone cement during the surgical procedure having a first end and a second end, the first end of the hollow tube adapted to be removably engaged with the threaded portion of the dispenser hub assembly. The shaft is axially displaceable through the hollow tube for controlled displacement of the bone cement through the second end of the hollow tube.
