摘要： A flexible plastic material catheter having a distal tubular member portion with a greater than 75 weight percent loading of a radiopaque agent for radiographic viewing. The catheter comprises an elongated member having a proximal portion and a distal end portion with a flexible, radiopaque plastic material having a durometer lower than that of the proximal portion. The plastic material of the distal end portion comprises a homogeneous and evenly dispersed composition of a 20 weight percent base thermoplastic, elastomer material such as a polyether block amide and 80 weight percent loading of a radiopaque agent such as tungsten. This distal end portion plastic material exhibits a durometer of approximately 47 on the Shore D scale, whereas the polyether block amide material exhibits a durometer of approximately 40 on the Shore D scale. The flex modulus of the polyether block amide material is in range of 23,000 to 75,000 pounds per square inch. The proximal end portion comprises a base thermoplastic material such as a polyamide elastomer material and a radiopaque agent of bismuth oxychloride.
