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 invention is directed to an ion plasma deposition (IPD) method adapted to coat polymer surfaces with highly adherent antimicrobial films. A controlled ion plasma deposition (IPD) process is used to coat a metal or polymer with a selected metal/metal oxide. Exposing the coated surface to ultraviolet light significantly improves the antimicrobial properties of the deposited coatings.

A method of using a disposable catheter sleeve to prevent infection. A method of using an indwelling catheter apparatus including a catheter tube comprising a first end for insertion into a patient's body and a disposable catheter sleeve wrapped around the catheter tube proximate to the first end of the catheter tube to prevent infection.

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 the composite exhibit good mechanical properties with improved ageing resistance.

This application relates to a production method for a medical balloon that can suppress the occurrence of the symptom of delayed-type allergy (Type IV) in addition to immediate-type allergy (Type I). The production method includes molding a composition containing a carboxy-modified conjugated diene polymer, a vulcanizing agent, and a xanthogen compound into the shape of a balloon. The molding of the composition into the shape of a balloon includes dipping a balloon-shaped mold in the composition in the form of latex.

A cable includes a sheath, and a coating film covering a circumference of the sheath. The coating film adheres to the sheath. The static friction coefficient of a surface of the coating film is smaller than the static friction coefficient of a surface of the sheath. The adhesion strength between the sheath and the coating film is 0.30 MPa or more.
