A polymeric tubular conduit including a polymeric tubular conduit wall having an outer tubular layer coaxially overlaying an inner tubular layer which defines a continuous tubular passage along a polymeric tubular conduit length of the polymeric tubular conduit; whereby the outer tubular layer, the inner tubular layer, or combinations thereof, include an amount of antimicrobial agent. The amount of antimicrobial agent can be sufficient to kill or inhibit growth of microorganisms in contact with a corresponding polymeric tubular conduit wall external surface, polymeric tubular conduit wall internal surface, or combinations thereof, of the polymeric tubular conduit wall.

The properties of a thermoformed polymeric article are modified by incorporation of an additive in a thermoplastic/thermoplastic elastic host matrix. The additive comprises a polydispersed hyperbranched polymer (HBP) or a branched monodispersed dendritic polymer (DP). The HBP or DP is linked to a plurality of oligomer chains. The additive migrates to the surface of the article during the thermoforming process.

A high-pressure tube comprises several co-extruded layers which include a reinforcing inner layer. Said reinforcing inner layer exhibits a mixture of a block copolymer and a homopolymer. As a result, a high-pressure tube is obtained the bending stiffness of which is reduced.

New stretchable electrically conductive composite materials comprising at least one polymer and a plurality of nanoparticles are provided, which exhibit high conductivity even at high strain levels. The composite may comprise polyurethane as the polymer and spherical gold nanoparticles. Such materials have conductivity levels as high as 11,000 Scm.sup.1 at 0% strain and 2,400 Scm.sup.1 at 110% strain. Furthermore, certain embodiments of the composite have a maximum tensile strain of 480% while still exhibiting conductivity of 35 Scm.sup.1. The inventive materials are highly flexible, highly conductive and suitable for a variety of applications, especially for advanced medical devices, implants, and flexible electronics. The disclosure also provides methods of making such stretchable electrically conductive nanocomposites, including formation by layer-by-layer and vacuum assisted flocculation. In certain embodiments, stretchable chiral plasmonic composite materials for use as optic devices and methods for making them are provided.

This invention relates to regenerable antimicrobial coatings with long-lasting efficacy for use in medical applications including implants, medical instruments or devices, and hospital equipment. The same coatings would also have broad utility in the consumer, industrial, and institutional markets. The coating technology would be based on sequestration of hydrogen peroxide (HP) by zinc oxide binders incorporated into the coatings.

The present invention provides a stretchable material suitable for use in an inflatable medical device. The stretchable material has at least one reinforcing polymer layer with a top and bottom side forming a porous matrix which is imbibed with a sealing material to infiltrate and substantially seal spaces of the porous matrix and extend beyond the reinforcing polymer layer to form a surface coating.

A balloon catheter includes a balloon which is both of high strength and radiopaque. The balloon includes an outer strengthened layer which includes a strengthening element at least partially embedded within the layer. Concentrically within the strengthened layer there is a radiopaque layer which includes a high concentration of radiopaque material distributed in the radiopaque layer. The strengthened layer acts as a support to the radiopaque layer which is otherwise be unable to withstand the pressure to which the balloon is normally inflated for deployment and in the course of a medical procedure. The structure provides a high strength radiopaque balloon with a relatively thin balloon wall optimizing balloon flexibility and wrappability. There is also disclosed a method of making a balloon which uses an internal support layer in a raw tubing which is then removed following formation of a balloon.
