AI Technical Summary
The electrodes of existing electrophysiological catheters or ablation catheters cannot simultaneously take into account both axial and circumferential positions during the unfolding, contact, and retraction processes, resulting in insufficient continuity and uniformity of ablation coverage and affecting the treatment effect.
By designing the first electrode connection part, the second electrode connection part, and the third electrode connection part, a continuous electrode node chain of vertex-edge-vertex is formed in the grid structure. The electrodes are not only set in the vertex region of the grid structure, but also in the edge region, ensuring that a continuous electrode coverage path is formed in both the circumferential and axial directions when the grid is unfolded.
It improves the continuity of the electrode coverage path and the uniformity of the ablation coverage, enhances the support strength and stability of the electrode, ensures that the electrode is not easily displaced during the ablation process, and improves the ablation efficiency and effect.
