A medical device for treatment of a stenosed body lumen, includes an open-ended cylindrical body carried on a distal end of a catheter for insertion of the device into the body lumen and placement at the stenosed site. The cylindrical body is movable between a collapsed position for insertion into the body lumen, and a radially expanded position pressed against the wall of the body lumen. In one embodiment the body sidewall is formed by a plurality of interconnected struts or elements defining openings therebetween, and at least one elongate ribbon is attached to an outer surface thereof for carrying a therapeutic agent. In another embodiment, the body is formed of interwoven elements defining a mesh-like structure, and the elements may comprise dissimilar materials, such as, e.g., copper and silver. In a further embodiment the body is formed of layers of different materials such as, e.g., copper, silver, and/or steel, laminated together. In a still further embodiment the device is designed for temporary placement of the catheter and body in a body lumen for treatment of a stenosed site, after which the catheter and body are withdrawn. In all forms the body may have an outwardly flared inlet end to reduce turbulence of fluid flowing through it, and/or a gel-like coating of a cholesterol-dissolving or blood clot dissolving agent may be placed on the device.

This invention provides composite yoga mats comprising a fabric sheet with a frictional material and/or loop holes to provide support, a stable surface, and moisture absorption for the practice of yoga.

Disclosed is an unique reclosable metal bottle in which a trim portion of the neck can be reused and mounted on the neck as a collar, or a separate collar provided, that has the structural rigidity necessary to form threads or lugs for recloseability. Thin wall metal bottles, having thicknesses on the order of thin wall metal cans currently in use, can be made using this process with minimal material waste since the trim neck portion is reused as a threaded collar. Structural rigidity and strength can be added by using fillers to backfill the indentations of the threads in the collar. Threads or lugs can be used, including pressure release lugs, that add both safety and convenience. Since the reclosable metal bottle is an all-metal container, the bottle can be recycled without introducing contaminants.

The invention relates to composite compositions having a matrix of polymer networks and dispersed phases of particulate or fibrous materials. The polymer matrix contains a polyurethane network formed by the reaction of a poly- or di-isocyanate and one or more saturated polyether or polyester polyols, and an optional polyisocyanurate network formed by the reaction of optionally added water and isocyanate. The matrix is filled with a particulate phase, which can be selected from one or more of a variety of components, such as fly ash particles, axially oriented fibers, fabrics, chopped random fibers, mineral fibers, ground waste glass, granite dust, or other solid waste materials. The addition of water can also serve to provide a blowing agent to the reaction mixture, resulting in a foamed structure, if such is desired.

The frame member may further include a third portion connectable to a support base, and the first to third portions may be integrally formed within the frame member.

A strut assembly to be used in conjunction with an embolic filtering device has varying strut thicknesses, with the thickness selected based at least in part on the flexing characteristics of the particular portion of the strut assembly. The strut assembly is formed with patterns having flexing portions and stable portions, with the flexing portions contributing to the flexibility of the strut assembly during delivery and recovery in the patient's vasculature. The stable portions remain relatively unflexed and stiff when being delivered or recovered from the patient's vasculature. The stable portions provide strength and increased radiopacity to the strut assembly which is needed when the strut assembly is deployed in the body vessel. The flexing portions act much like a mechanical hinges in providing the needed flexibility to resiliently bend when being delivered through tortuous anatomy of the patient.
