    Area of Science:

    • Interventional Radiology
    • Medical Device Technology

    Background:

    • Minimally invasive procedures require reliable access techniques.
    • Current methods may involve multiple guide wires and potential complications.

    Purpose of the Study:

    • To describe a novel coaxial access system for drainage procedures.
    • To evaluate the safety and efficacy of this new technique.

    Main Methods:

    • A 22-gauge removable hub needle serves as an initial guide wire.
    • The needle is replaced by an 18-gauge cannula for coaxial access.
    • A single 0.038-inch guide wire is used throughout the procedure.

    Main Results:

    • The technique was successfully applied in 150 nephrostomy and biliary drainage procedures.
