  • Catheter having highly radiopaque, flexible tip
    Patent number: 5171232
    Abstract: A flexible plastic catheter defines a flexible, distal tip. In accordance with this invention, the distal tip comprises a plastic formulation containing sufficient radiopaque agent to be substantially more radiopaque and preferably softer than portions of the catheter proximal to the tip. Thus, the distal tip area of the catheter can be flexible to avoid possible tissue damage as the catheter is advanced, but is still readily visible by x-ray. At the same time, the majority of the catheter may be of normal flexibility and strength.
    Type: Grant
    Filed: July 12, 1991
    Date of Patent: December 15, 1992
    Assignee: Cordis Corporation
    Inventors: Miguel A. Castillo, Javier E. Castaneda, Eric Glemser
