    A new catheter design facilitates precise selective and superselective catheterization of distal brachiocephalic arteries. This innovative device achieved over 95% success in embolization procedures across 209 patients.

    Area of Science:

    • Vascular Surgery
    • Interventional Radiology
    • Medical Device Development

    Background:

    • Selective and superselective catheterization of distal brachiocephalic arteries is crucial for various endovascular procedures.
    • Existing catheter technologies may present challenges in achieving precise navigation and stable positioning in these complex arterial networks.

    Purpose of the Study:

    • To report the development of a novel catheter system engineered for enhanced ease and reproducibility in selective and superselective catheterization.
    • To evaluate the efficacy and safety of this new catheter in embolization procedures targeting distal brachiocephalic artery branches.

    Main Methods:

    • The catheter features a proximal 6- or 7-F braided shaft and a 10 cm distal segment made of thin-walled polyurethane (4- or 5-F diameter).

  • The distal tip incorporates a 105-degree curve and a non-tapered design for improved maneuverability and engagement.
  • The catheter's performance was assessed in 209 patients undergoing 277 embolization procedures.

    • Main Results:

    • Successful catheterization of the target vessels was achieved in over 95% of the procedures.
    • The catheter design demonstrated ease of use and reproducibility in navigating and accessing distal arterial branches.

    Conclusions:

    • The developed catheter system offers a significant advancement for selective and superselective catheterization of distal brachiocephalic arteries.
    • Its high success rate and ease of use suggest potential for improved outcomes in endovascular embolization therapies.
