  • Torque controlled tubing
    Patent number: 5085649
    Abstract: Catheter tubing suitable for medical uses is disclosed, comprising an interior tubular portion and a concentric outer shell, wherein said interior portion extends beyond said concentric outer shell on at least one end of the longitudinal axis, and wherein the hardness of the concentric outer shell exceeds the hardness of the interior tubular portion, the interior tubular portion further comprising at least two resins co-tapered with respect to each other, the hardness of the innermost of which exceeds the hardness of the outermost.

  • Radiopaque polyurethane resin compositions
    Patent number: 4283447
    Abstract: Radiopaque compositions are provided by formulating polyurethane resins, alone, or combined with vinyl resins, with alkyl or alkoxyalkyl 2,5-diiodobenzoates, 2,3,4,6-tetraiodobenzoates or mixtures thereof. The compositions are useful in the manufacture of X-ray opaque medical devices, particularly medical surgical tubing. Surgical tubing with excellent plastic memory is provided, well adapted to forming flares and curved tips necessary for selective renal and celial arteriography. Multi-wall and co-tapered multiwall tubing constructions are also disclosed.
