    A novel metal-tipped catheter can reach high temperatures for angiopyroplasty using external radiofrequency (RF) energy. This cost-effective device offers a promising alternative to existing laser-based angioplasty systems.

    Area of Science:

    • Medical Devices
    • Cardiovascular Interventions
    • Biomedical Engineering

    Background:

    • Angioplasty procedures require high temperatures to be effective.
    • Existing laser systems are expensive and complex.
    • A need exists for more accessible and cost-effective thermal ablation technologies.

    Purpose of the Study:

    • To develop a novel catheter for angiopyroplasty capable of inducing and withstanding high temperatures.
    • To investigate the use of radiofrequency (RF) energy for thermal ablation in vascular procedures.
    • To present a cost-effective alternative to laser-based angioplasty systems.

    Main Methods:

    • Development of a metal-tipped catheter designed for high-temperature applications.
    • Utilization of external radiofrequency (RF) energy focused on the catheter tip.
