    Percutaneous coronary intervention (PCI) utilizes catheters to treat occluded blood vessels by placing stents to restore blood flow.

  • 2

    Steerable catheters have varying bending capabilities, with minimum bending radii reported between 8.13mm and 171mm.

  • 3

    Path planning for catheterization must consider curvature constraints to avoid exceeding the catheter's bending capabilities.

  • 4

    The proposed two-phase path planning approach optimizes catheter paths by combining global cubic B-spline curves with local curvature adjustments.

  • 5

    Real-time path replanning is essential due to intra-operative environmental changes, necessitating low computational time for effective navigation.
