Title:
CATHETER SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/187154
Kind Code:
A1
Abstract:
Provided is a catheter system capable of outputting a high-voltage pulse in a state in which the cardiac muscle is in the refractory period regardless of the arrangement relationship of a pacing electrode or an ablation electrode. This catheter system has: an ablation catheter (10) having an ablation electrode (21); and a control unit (14) for controlling power supply to the ablation electrode (21). The control unit (14) has: a reception means (50) for receiving a timing of power supply to pacing electrodes (41), (45) disposed at positions different from that of the ablation electrode (21) and the value of the time required to transmit an electric signal from the pacing electrodes (41), (45) to the position of the ablation electrode (21); and an adjustment means (51) for adjusting the timing of power supply to the ablation electrode (21) on the basis of the timing of power supply to the pacing electrodes (41), (45) and the value of the transmission time received by the reception unit (50).
