Title (EN) SYSTEMS AND METHODS FOR INTRAVASCULAR CATHETER POSITIONING AND/OR NERVE STIMULATION
(FR) SYSTÈMES ET PROCÉDÉS DE POSITIONNEMENT DE CATHÉTER INTRAVASCULAIRE ET/OU DE STIMULATION DE NERF
Abstract:
(EN) A method for positioning an intravascular catheter may include inserting the intravascular catheter into a venous system of a patient, wherein the catheter includes a plurality of electrodes, and multiple electrodes of the plurality of electrodes are configured to emit electrical signals; positioning a distal portion of the catheter in a first position; using one or more electrodes of the plurality of electrodes to acquire an ECG signal; based on the acquired ECG signal, adjusting the distal portion of the catheter to a second position different from the first position; identifying at least one first electrode of the plurality of electrodes to stimulate a first nerve; identifying at least one second electrode of the plurality of electrodes to stimulate a second nerve; and stimulating at least one of the first and second nerves to cause a contraction of a respiratory muscle.
(FR) Un procédé permettant de positionner un cathéter intravasculaire peut consister à insérer le cathéter intravasculaire dans un système veineux d'un patient, le cathéter comprenant une pluralité d'électrodes, et de multiples électrodes de la pluralité d'électrodes sont configurées pour émettre des signaux électriques; positionner une partie distale du cathéter dans une première position; utiliser une ou plusieurs électrodes de la pluralité d'électrodes pour acquérir un signal ECG; sur la base du signal ECG acquis, ajuster la partie distale du cathéter à une seconde position différente de la première position; identifier au moins une première électrode de la pluralité d'électrodes pour stimuler un premier nerf; identifier au moins une seconde électrode de la pluralité d'électrodes pour stimuler un second nerf; et stimuler au moins l'un des premier et second nerfs pour provoquer une contraction d'un muscle respiratoire.
