    摘要: A medical device for guiding through anatomy, such as a catheter or guidewire, with a tubular body that has been slotted to enhance bending flexibility, and a polymer liner with an anti-collapsing structure, and a method of making a medical device with a kink-resistant corrugated tubular member and an anti-collapsing structure. Anti collapsing structures may be helical or annular, and may be wire, such as ribbon wire, grooves in the liner, corrugations, or a braid. Liners may be bonded to the anti-collapsing structure, or may have two layers, with the anti-collapsing structure between the layers. Corrugations may be formed between sections of the anti-collapsing ‘structure with heat, pressure, stretching, compression, a mold, or a combination thereof, and may extend inward or outward. Shape or wall thickness may vary along the length to provide a varying bending stiffness. Slots may be formed in groups of two, three, or more, and adjacent groups may be rotated about the axis forming a helical pattern.

    摘要: Novel compositions comprising photoactive urethane acrylate resins and an ethylenically unsaturated reactive diluent are disclosed. The urethane acrylate resin comprises the reaction product of a polyhydric acrylate monomer and an isocyanurate. The compositions find particular application in negative photoresist compositions and exhibit improved blocking resistance compared with other negative photoresist compositions. Methods for using the compositions are also disclosed.
