The present invention provides fabrics that have unique chemical, electrical, and thermal properties. The fabrics comprise layers of yarns woven together wherein the yarns further comprise carbon nanotube fibers. These carbon nanotube fibers may be either single-walled or multi-walled carbon nanotubes. The use of carbon nanotube fibers allows the fabrics to insulate, semi-conduct or super-conduct electrical charges. Additionally, the thermal properties of carbon nanotubes allow thermal energy to flow efficiently between the fabric and a heat sink or source. Additional yarns of materials other than carbon nanotubes can be integrated or woven into the fabric to provide other unique properties for the fabric. These fabrics can be layered to form unique garments or structures.

A protective article formed of a laminate between at least a layer of a liquid-impermeable, vapor-permeable barrier, and at least a layer of a stretchable or elastomeric, nonwoven fiber web is described. The barrier is reinforced at least on one side by the nonwoven fiber web, which remains elastic after being bonded to the barrier layer. The elasticity of both barrier and bonded fiber layers simulate the flexibility of natural or synthetic latex or other polymer films. The nonwoven fiber web includes at least about 75% of individual fibers with a length of over about 1 mm, and the fibers are substantially continuous. A second nonwoven web, a second barrier layer, or both may be attached to the exterior side of the breathable barrier. An elastomeric material coating, such as either a nature or synthetic latex or other polymers, may be applied over at least a portion of the article to provide for additional protection.

A flushable catheter assembly having features to enable selective activation of fluid flow through the catheter assembly is disclosed herein. A septum is placed within the catheter adapter of the catheter assembly and includes a pathway that is closed prior to being biased open via a septum activator also positioned within the catheter adapter. A plurality of air vent channels is interposed between the septum and the inner surface of the catheter adapter to permit “flashback” of blood during insertion of the catheter into a patient. The septum activator is advanced through the pathway of the septum as a coupler is attached to a proximal opening of the catheter adapter.

The present invention relates to a process for preparing surface modifications having an improved antithrombogenic activity, whereby the improvement is achieved by treating heparin at a temperature above 40° C. or a pH in the rage of 9-14 or in contact with nucleophilic catalysts before attaching said heparin to the surface to be modified.

In some embodiments, a cam assembly and strap based closure system using a spiral is configured for bringing two sides of an article together.

Articles such as medical devices are selectively coated with a lubricious coating. A temporary coating, formed from an aqueous solution of a water-soluble polymer of low to moderate molecular weight, is painted onto those portions of the article which are to remain free of any coating in the final product. Then, the entire article is coated with a material which forms a lubricious coating. The article is then soaked in water to loosen the coatings at the locations at which the temporary coating was applied. The coatings are cleanly removed from those locations, leaving an article with a lubricious coating in some portions, and which is uncoated in the remaining portions. The process can be used in coating portions of catheters, surgical gloves, contact lenses, and any other articles which require a lubricious coating only on a portion of the surface of the article.
