Abstract

The invention provides an electrode assembly, an electrophysiological catheter and an electrophysiological system. The electrode assembly comprises an electrode main body, a sub-electrode assembly and an electric transmission line, wherein the sub-electrode assembly and the electric transmission line are arranged on the electrode main body; the electric transmission line comprises a plurality of ablation lines; the sub-electrode assembly comprises a plurality of first ablation electrodes and a plurality of second ablation electrodes; each ablation line comprises a transmission main line, a first transmission branch line and a second transmission branch line; the first ablation electrodes and the second ablation electrodes are electrically connected with the output ends of the corresponding first transmission branch lines and the output ends of the corresponding second transmission branch lines respectively; and the input ends of the first transmission branch lines and the input ends of the second transmission branch lines are intersected at the transmission main lines. The transmission branch lines of different ablation electrodes are arranged in a parallel manner, so that the resistance value of the ablation lines is reduced, the current resistance of the ablation lines is improved, meanwhile, the ablation boundary of the catheter is also improved, and the ablation depth is increased.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an electrode assembly, an electrophysiological catheter and an electrophysiological system. Background technique [0002] In the field of electrophysiological therapy, the use of electrophysiological catheters to transmit energy for tissue ablation is a common method. Specifically, the electrophysiological catheter includes a catheter and an electrode assembly arranged on the head end of the catheter. After the head end of the catheter is inserted into the target point to be treated, energy is supplied to the electrode assembly through the energy supply platform, and the electrode assembly and The target is abutted to deliver energy to the target for ablation. Among them, the commonly used energy is the pulsed electric field of irreversible electroporation. The pulsed electric field is cell-selective, especially in the process of pulmonary vein isolation and ablation, wh...
