Title:
VISUAL DEEP ABLATION CATHETER
Document Type and Number:
WIPO Patent Application WO/2023/109334
Kind Code:
A1
Abstract:
The present invention relates to the fields of medical electrophysiology catheter technology and cardiac electrophysiology ablation, and in particular to a visual deep ablation catheter, comprising a sheath and a catheter, and further comprising a handle assembly and an axial movement driving component mounted in the handle assembly. The axial movement driving component can conduct a spiral motion in the handle assembly and drive the catheter to move. According to the ablation catheter in the present invention, the sheath and the catheter are integrally designed, and the relative movement of the catheter in the sheath is limited by the axial movement driving component; thus, the movement of the catheter relative to the sheath can be controlled more accurately, and when a deep lesion in the tissue is treated, the relative position of the catheter and the sheath can be accurately controlled.
