Abstract
The disclosure notably relates to a system for phrenic nerve stimulation. The stimulation system comprises a catheter (200) including one or more intravascular electrodes each arranged on a distal portion (240) of the catheter. The catheter is configured to be introduced in the superior vena cava (VC) of a human patient. The stimulation system also comprises an extracorporeal electrode patch (260) configured to be affixed to the patient opposite to the distal portion relative to the phrenic nerve. The extracorporeal electrode patch is operable in a bipolar mode with the one or more intravascular electrodes. Such a system forms an improved solution for phrenic nerve stimulation, in particular during a cryoablation procedure.

A system for phrenic nerve stimulation, the system comprising:
- a catheter (200, . . . , 1000) including one or more intravascular electrodes (310, . . . , 1010) each arranged on a distal portion (240, . . . , 1040) of the catheter, the catheter being configured to be introduced in the superior vena cava (VC) of a human patient so as to position the distal portion in the superior vena cava, in the right brachiocephalic vein, and/or in the right subclavian vein, and
- an extracorporeal electrode patch (260, 460) configured to be affixed to the patient opposite to the distal portion relative to the phrenic nerve, the extracorporeal electrode patch being operable in a bipolar mode with the one or more intravascular electrodes.
