Methods of making the coatings for medical devices are also disclosed.

An endoscopic treatment instrument including a dual tube inserted into a channel of an endoscope, the dual tube including an outer tube and an inner tube being inserted into the outer tube and moving forward and backward relative to the outer tube. The outer tube and the inner tube are made of a plastic material composed of a mixture of an organic polymer and a silicone compound, the organic polymer is polypropylene and the silicone compound is polydimethylsiloxane, and the polypropylene is 90 to 99.5 wt % and the polydimethylsiloxane is 0.5 to 10 wt %.

Novel, lubricious coatings for medical devices are disclosed. The coatings provide improved lubricity and durability, and are readily applied in coating processes. The present invention is also directed to a novel platinum catalyst for use in such coatings. The catalyst provides for rapid curing, while inhibiting cross-linking at ambient temperatures, thereby improving the production pot life of the coatings.

An implantable medical device for lubrication of a synovial joint having a joint cavity is provided. The implantable device comprises a solid lubricant and a feeding device, wherein said feeding device is adapted to feed said solid lubricant into the joint cavity for lubricating the synovial joint.

The present invention, in general, relates to the field of poly(2-oxazolines) (PAOx), more in particular poly(2-methoxymethyl-2-oxazoline) (PMeOMeOX) and poly(2-dimethylamino-2-oxazoline) (PDMAOx). The present invention also provides methods for preparing these PAOx, as well as compositions and uses comprising said PAOx.

In an embodiment, a coated medical device is included, the coated medical device including a substrate and a polymeric layer disposed over the substrate. The polymeric layer includes a polymer and has an exterior surface. The coated medical device further includes a plurality of salt groups bonded to the polymer of the polymeric layer and disposed on the exterior surface of the polymeric layer. The salt groups can be the reaction product of a reactive group with an acid or base. In an embodiment, a method of making a medical device is included. Other embodiments are also included herein.

Hygienic Hydrophilic coatings, hydrophilic coating formulations and wetting fluids that include an anti-infective agent.

The present disclosure describes a strategy to create self-healing, slippery self-lubricating polymers. Lubricating liquids with affinities to polymers can be utilized to get absorbed within the polymer and form a lubricant layer (of the lubricating liquid) on the polymer. The lubricant layer can repel a wide range of materials, including simple and complex fluids (water, hydrocarbons, crude oil and bodily fluids), restore liquid-repellency after physical damage, and resist ice, microorganisms and insects adhesion. Some exemplary applications where self-lubricating polymers will be useful include energy-efficient, friction-reduction fluid handling and transportation, medical devices, anti-icing, optical sensing, and as self-cleaning, and anti-fouling materials operating in extreme environments.
