Electrode structures for transvascular nerve stimulation combine electrodes with an electrically-insulating backing layer. The backing layer increases the electrical impedance of electrical paths through blood in a lumen of a blood vessel and consequently increases the flow of electrical current through surrounding tissues. The electrode structures may be applied to stimulate nerves such as the phrenic, vagus, trigeminal, obturator or other nerves.

La présente invention porte sur des structures d'électrode permettant une neurostimulation transvasculaire, lesquelles combinent des électrodes avec une couche support électriquement isolante. La couche support augmente l'impédance électrique des trajets électriques à travers le sang dans une lumière d'un vaisseau sanguin et, par conséquent, augmente le flux du courant électrique à travers les tissus environnants. Les structures d'électrode peuvent être appliquées pour stimuler des nerfs tels que le nerf phrénique, le nerf vague, le nerf trijumeau, le nerf obturateur ou d'autres nerfs.
