    摘要： Articles such as catheters or balloons that have an ester-linked poly(ester-block-amide) substrate have a lubricious hydrogel coating which suppresses particle development under accelerated aging conditions. A polymerizable coating composition is applied to the substrate without application of an intervening primer layer and cured. The coating composition comprises an uncrosslinked polyvinylpyrrolidone polymer that is free of attached photoinitiator groups and at least one polyfunctional ethylenically unsaturated monomer.

    摘要： A method of making a flexible, durable catheter tip is achieved by providing a catheter tip, and in some embodiments, applying heat energy only to the distal portion of a catheter tip. In other embodiments, the method includes ablating a portion of the outer diameter of the proximal region material. In at least one embodiment, the method includes manufacturing a catheter tip with a layer of a harder material disposed about a first layer of a relatively softer material and then ablating at least a portion of the harder material. In some embodiments, the method includes dipping at least a portion of the distal region of the catheter tip into a chemical bath. In some embodiments, the method includes providing a catheter tip made of a tip material, adding a curable adhesive to at least a portion of the distal region, and then applying heat energy to cure the curable adhesive.

    摘要： A tubular member comprises a balloon having a body portion positioned between a first end and a second end. The body portion is constructed from an extruded matrix material and at least one stripe of a second extruded material. The at least one stripe is at least partially disposed within the matrix material. The proximal end and the distal end are constructed from the matrix material.
