Abstract
A radio-frequency ablation catheter comprises a handle having a proximal end and a distal end, an outer tube assembly having a proximal end and a distal end, and an inner tube assembly having a proximal end and a distal end; the proximal end of the outer tube assembly is connected to the distal end of the handle; the proximal end of the inner tube assembly is connected to the distal end of the handle; the inner tube assembly can be driven by the handle to rotate relative to the outer tube assembly; the inner tube assembly comprises a branch electrode assembly, and the branch electrode assembly comprises a plurality of branch electrodes distributed at intervals in the circumferential direction. The branch electrode assembly of the radio-frequency ablation catheter and the radio-frequency ablation system can rotate relative to the outer tube assembly to avoid blood vessels.
