A screw cap removably associated with a bone screw, the bone screw comprising: a head having a set of interior threads, one of the set of interior threads having a circular slot; a magnet; and an interior cavity located within the bone screw and configured to house the magnet; the screw cap comprising: a top end configured to receive a driving means for inserting the screw cap into, and removing the screw cap from, the head; a body having a set of cap threads, one of the set of cap threads comprising a locking bead; and an annular recess concentrically lining a portion of the body, the annular recess comprising a leakage ring for establishing a seal between the screw cap and the head; wherein an association of the set of cap threads with the set of interior threads causes the locking bead to be engaged with the circular slot.

A thermoplastic elastomer (TPE) material includes a styrene-ethylene-butadiene-styrene block copolymer rubber, a Food and Drug Administration (FDA) grade mineral oil, and a heat and UV stabilizer package. A method includes extruding a thermoplastic elastomer (TPE) material into a thin film roll with a thickness from 0.003″ to 0.010″, the TPE material comprising a styrene-ethylene-butadiene-styrene block copolymer rubber, a Food and Drug Administration (FDA) grade mineral oil, and a heat and UV stabilizer package.

The present invention relates to a method of preparing reduced graphene oxide, incorporation of the reduced graphene oxide into polyisoprene latex to provide a polyisoprene latex graphene composite and elastomeric articles prepared using the polyisoprene latex-graphene composite. In particular, the reduction of graphene oxide is accomplished without the use of strong reducing agents and organic solvents and incorporation of the reduced graphene oxide into polyisoprene latex is accomplished using room temperature latex mixing method or hot maturation. The resultant composite exhibits good colloid stability and polyisoprene latex films produced from the composite exhibit good mechanical properties with improved ageing resistance.

Provided are multilayer elastomer compositions such as multilayer films which possess the ability to self-repair upon puncturing. The multilayer elastomer compositions may be prepared from, for example, styrenic block copolymers and find use in the manufacture of thin walled articles, for example gloves, particularly medical or industrial gloves.

A medical device component is provided. The medical device component may include a body having a first surface being at least partially formed from a markable material having a first color, the markable material having a characteristic that an area exposed to laser irradiation of a predetermined wavelength of ultraviolet light changes to a second color different from the first color; a film covering at least a portion of the first surface of the body, the film having a transmittance at the predetermined wavelength of ultraviolet light of at least 5%; and a visible mark on the markable material at the first surface of the body covered by the film. The visible mark may include one or more areas of the markable material at the first surface having the second color. Methods of manufacturing the medical device component are also provided.

There is provided a method for decreasing leakage of matter from an object to a surrounding, said object being coated with a coating at least partially applied on the object, said coating comprising an at least partially covering layer comprising silver, said object optionally comprising area(s) without said layer, said coating comprising metal particles applied on the layer and optionally on areas without said layer, said metal particles comprising palladium and at least one metal selected from the group consisting of gold, ruthenium, rhodium, osmium, iridium, niobium, neodymium and platinum and wherein the amount of the metal particles is in the interval 0.01-8 μg/cm.sup.2. Advantages include that leakage of matter such as latex allergens of metal ions can be reduced while the coating is both biocompatible and antimicrobial. Further, the blood clotting can be reduced.

The present application relates to an elastomeric article, such as a glove, comprising: (i) an elastomeric film comprising one or more film layers, and including an external surface and an internal surface, (ii) an antimicrobial agent that is effective against both beneficial and harmful microorganisms on the external surface of the elastomeric film, and (iii) a skin-protective agent selected from a probiotic, a prebiotic, or a combination thereof on the internal surface of the elastomeric film; wherein the inner surface of the film is free of an antimicrobially-effective amount of an antimicrobial agent that is effective against both beneficial and harmful microorganisms. The elastomeric articles may further comprise a barrier film layer that provides separation between the antimicrobial agent and the skin-protective agent. Also described are methods for the manufacture of such articles.
