A medical device includes: a substrate layer; an adhesive layer formed on at least a part of the substrate layer and containing a hydrophilic copolymer (1) containing a structural unit derived from a polymerizable monomer (A) having a sulfobetaine structure, a structural unit derived from a polymerizable monomer (B) having at least one group selected from the group consisting of a sulfonic acid group (—SO.sub.3H), a sulfuric acid group (—OSO.sub.3H), a sulfurous acid group (—OSO.sub.2H), and salt groups thereof, and a structural unit derived from a polymerizable monomer (C) having a photoreactive group; and a surface lubricious layer formed on at least a part of the adhesive layer and containing a polymer containing a structural unit derived from acrylamide and a hydrophilic copolymer (2).

The present disclosure relates to the surface modification of substrates using poly (2-oxazine)s. Specifically, the present disclosure provides the use one or more poly(2-alkyl-2-oxazine) or copolymers containing poly(2-alkyl-2-oxazine) in surface modification of a substrate. More in particular the present disclosure provides substrates having attached thereto, or associated therewith, one or more poly(2-alkyl-2-oxazine) or copolymers containing poly(2-alkyl-2-oxazine); wherein said alkyl is preferentially selected from the list comprising methyl and ethyl. The present disclosure also provides methods for preparing such substrates and uses thereof.

Hydration mediums, assemblies containing hydration mediums and methods of making the same are disclosed. The hydration mediums are intended for hydrating or wetting a medical device such as a catheter and comprise a hydration foam. Furthermore, methods and products involving hydrophilic substances are disclosed e.g. involving mucilage, deep eutectic liquids, antifreeze substances or cryoprotectants, oil or a hydration medium together with water, surfactant, polyol and stabilizer.

A plurality of structural layers having different properties are nested together to form the medical balloon. Certain embodiments include at least one layer comprising a fiber-reinforced polymer. The layers of the balloons can slide relative to one another in use. A structural layer may comprise metal reinforcing fibers suspended in a polymer matrix.

A medical device comprising a surface, wherein a sulfanilamide is associated with the surface, and methods for making the same.

Medical products containing hydration mediums, hydration mediums, and methods of making the same.

An orthopedic prosthesis includes a head which internally accommodates the major motion of a patient, e.g., during walking, thereby reducing wear against a cup or liner. A neck may be utilized which rotates within the distal member about an axis aligned with the major motion of the patient. The orthopedic prosthesis may also include a sacrificial anode, a seal made of natural fibers, and utilize lubricant made of honey.

A medical device, such as a catheter, is disclosed, comprising a substrate and having on its surface, on at least a part thereof, a hydrophilic surface layer providing low-friction surface character of the medical device when wetted by a wetting fluid. At least one base layer of the substrate, including the hydrophilic surface layer, is made of a polymer blend comprising at least one base polymer and at least one hydrophilic polymer, and wherein the concentration of the at least one hydrophilic polymer is higher in the hydrophilic surface layer than in the rest of the base layer. A method for producing such a medical device is also disclosed.

A composition for lubricant formulations is disclosed. The composition may include hypochlorite, dimethicone, and an emulsifier for improvement of lubricity. Methods of making and using the lubricant formulations are also disclosed.

The invention relates to balloon coatings and their use in delivering drugs via a drug-eluting balloon. The delivery can be, e.g., to a vessel wall.
