A tube connection part adapted to accommodate a flexible tube made from a material comprising polyvinyl chloride, wherein said tube connection part comprises a sleeve adapted to form an overlapping region between said tube connection part and said tube, wherein an adhesion promoting agent is deposited on at least a subsection of a surface of said sleeve, characterized in that the adhesion promoting agent comprises a styrene-butadiene block copolymer.

A plasticized nylon and a medical device including plasticized nylon. The medical device may be a dilatation balloon. Also disclosed are methods of plasticizing nylon.

Hydration mediums, assemblies containing hydration mediums and methods of making the same.

Methods of varying the stiffness of polymeric medical tubes.

The invention provides an intermittent catheter comprising a hollow polymeric tubular body comprising a base polymer and further comprising an amphiphilic additive at and/or on an outer surface of the body, wherein one or both of the base polymer and the additive are independently cross-linked and/or the base polymer and additive are cross-linked with each other.

A catheter having a shaft made from polyvinyl alcohol where in the shaft has a varying stiffness along the length of the shaft.

Polymeric tubing containing extractable component(s) for use in medical articles include a tube and a vapor-deposited coating of a barrier polymer covering at least a portion of the tube. The barrier polymer is derived from at least one ethylenically unsaturated monomer. The vapor-deposited polymer coating reduces the extraction of extractable component(s) from the tube. The barrier polymer is parylene or a copolymer of parylene. The polymer coated tubing can be used in stethoscopes.

PURPOSE: The present invention provides a polyvinyl chloride resin composition which is superior in heat stability and processability and has less elution from the composition. CONSTITUTION: a polyvinyl chloride resin composition comprising 100 parts by weight of a polyvinyl chloride resin, 10 to 120 parts by weight of di(2-ethylhexyl)terephthalate, and 0.5 to 20 parts by weight of epoxidized vegetable oil having a peroxide number of 5 or less.

Tubing, such as medical tubing for administration of intravenous fluid, can include an outer layer on an inner layer, and, optionally additional layers, in which at least the outer layer and the inner layer are made of a same polymeric material but the outer and inner layers have differing amounts or differing types of a plasticizer such that a hardness of the outer layer is greater than a hardness of the inner layer.

Zwitterionic carboxybetaine copolymers and their use in coatings to impart non-fouling and functionality to surfaces, particularly surfaces of blood-contacting medical devices.
