Abstract
The disclosure notably relates to a system for phrenic nerve stimulation. The stimulation system comprises a catheter including one or more intravascular electrodes each arranged on a distal portion of the catheter. The catheter is configured to be introduced in the superior vena cava of a human patient. The stimulation system also comprises an extracorporeal electrode patch 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.
Claims28
A system for phrenic nerve stimulation, the system comprising:
- a catheter including one or more intravascular electrodes each arranged on a distal portion of the catheter, the catheter being configured to be introduced in the superior vena cava 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 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.
A method comprising performing phrenic nerve stimulation, the phrenic nerve stimulation including:
- providing a catheter including one or more intravascular electrodes each arranged on a distal portion of the catheter;
- providing an extracorporeal electrode patch operable in a bipolar mode with the one or more intravascular electrodes;
- introducing the stimulation catheter in the superior vena cava of a human patient;
- positioning the distal portion of the catheter in the superior vena cava, in the right brachiocephalic vein, and/or in the right subclavian vein;
- affixing the extracorporeal electrode patch to a human patient opposite to the distal portion relative to a phrenic nerve of the human patient;
- operating the extracorporeal electrode patch in a bipolar mode with the one or more intravascular electrodes to perform phrenic nerve stimulation.
A non-transitory data storage medium having recorded thereon a computer program comprising executable code for operating an extracorporeal electrode patch in a bipolar mode with one or more intravascular electrodes arranged on a distal portion of a catheter to perform phrenic nerve stimulation, so as to perform phrenic stimulation when the catheter is introduced in the superior vena cava of a human patient such that the distal portion is positioned in the superior vena cava, in the right brachiocephalic vein, and/or in the right subclavian vein, and the extracorporeal electrode is affixed to the patient opposite to the distal portion relative to the phrenic nerve.
