The present invention provides a device and assembly for electrically and/or chemically stimulating individual ganglion and a plurality of ganglia of the nervous system, and particularly to ganglia of the sympathetic nerve chain. A device is provided that generally wraps around an individual ganglion and conforms to the shape of the ganglion without exerting excessive pressure on the ganglion to damage the ganglion. An assembly (200) is also provided that includes an axially elongated shaft (170) that can be positioned adjacent to the sympathetic nerve chain and that can receive a plurality of ganglion stimulators (240) that can slidably engage with the outer surface of the shaft. As additional ganglia are desired to be stimulated, each of the plurality of ganglion stimulators can be added to the shaft to engage the outer surface of the shaft and can be positioned adjacent to the ganglia desired to be stimulated.

La présente invention concerne un dispositif et un ensemble conçus pour stimuler électriquement et/ou chimiquement un ganglion individuel et une pluralité de ganglions du système nerveux, notamment des ganglions de la chaîne nerveuse sympathique. Le dispositif selon cette invention s'enroule généralement autour d'un ganglion individuel et se conforme à la forme du ganglion sans exercer de pression excessive sur le ganglion pouvant l'endommager. L'ensemble selon cette invention comprend une tige allongée en direction axiale qui peut être placée de manière adjacente à la chaîne nerveuse sympathique et qui peut recevoir une pluralité de stimulateurs de ganglion pouvant venir en prise par coulissement avec la surface extérieure de la tige. Lorsque l'on souhaite stimuler des ganglions supplémentaires, chacun des stimulateurs de ganglion peut être ajouté à la tige afin de venir en prise avec la surface extérieure de la tige et peut être placé de manière adjacente aux ganglions que l'on souhaite stimuler.
