    Area of Science:

    • Cardiovascular Surgery
    • Medical Instrumentation
    • Laser Technology

    Context:

    • Traditional surgical approaches for cardiac conductive pathways can be invasive.
    • Minimally invasive techniques are crucial for reducing patient recovery time and risks.
    • Visual control is essential for accurate targeting during cardiac interventions.

    Purpose:

    • To describe two novel experimental cardioendoscopes for laser surgery on cardiac conductive pathways.
    • To detail the design and implementation of rigid and flexible cardioendoscopes.
    • To evaluate the visualization and laser delivery capabilities of these new instruments.

    Summary:

    • Two original cardioendoscope designs, a rigid type (based on Fridel's bronchoscope) and a flexible transvenous version, are presented for laser surgery on heart conductive pathways.
    • Both devices utilize a saline-filled transparent balloon at the distal end for visualizing intracardiac reference points.
    • Laser energy is delivered through an optical fiber positioned within the balloon, allowing for targeted irradiation of cardiac structures.

    Impact:

    • These novel cardioendoscopes offer potential for enhanced precision in laser surgery on cardiac conductive pathways.
    • The transvenous approach may provide a less invasive alternative for certain cardiac procedures.
    • Further research could lead to improved outcomes in treating cardiac arrhythmias and other conductive pathway disorders.
