Pulse electric field generator

Abstract

The invention discloses a pulsed electric field generator, which comprises a group of output channels, and each output channel is respectively connected with or disconnected from one electrode in a group of electrodes of an ablation device; the pulse generation module is used for generating a pulse sequence and is connected with one group of output channels; the switch module is used for controlling connection or disconnection between the output channel and the electrode; and the main control module is used for controlling the pulse generation module to generate a pulse sequence during use and controlling the switch module to control the output channel to be connected with the electrode, so that the pulse sequence is transmitted to the electrode. The pulse generation module of the pulse electric field generator generates the pulse sequence under the control of the main control module, and the main control module also controls the connection and disconnection between the group of output channels of the pulses and the group of electrodes through the switch module, so that the generated pulses can be accurately delivered to tissues needing ablation.

Description

technical field [0001] The invention relates to the technical field of ablation, in particular to a pulsed electric field generator. Background technique [0002] Atrial fibrillation is the most common cardiac arrhythmia, and catheter ablation is an effective means of restoring and maintaining heart rhythm in patients with AF. At present, the commonly used ablation energy is mainly radio frequency energy, supplemented by cryoenergy. These two ablation methods have their own advantages, but also have corresponding limitations. It is selective and depends on the adhering force of the catheter, and may cause damage to the adjacent esophagus, coronary artery or phrenic nerve, thereby affecting the therapeutic effect. Pulse ablation is a new ablation method using high-voltage electric field as energy. It is a non-thermal ablation technology with tissue selectivity. By designing an appropriate pulse electric field and releasing multiple high-voltage pulses in a short time for abl...
