  • Catheter with double step-down bore
    Patent number: 5069673
    Abstract: A catheter defines a flexible tubular body and a tubular tip carrier at the distal end of the body. At last the majority of the tubular body defines a first bore portion having a first meter. The catheter defines side holes adjacent the distal end, with the catheter defining a second bore portion distal to the side holes having a second diameter which is less than the first diameter. The catheter also defines an intermediate, tubular portion between the first and second bore portions, the intermediate portion having a third bore diameter that is less than the first diameter and greater than the second diameter. The intermediate portion also defines a thicker catheter wall than the catheter wall defining the first bore portion.
