Le syst\u00e8me de d\u00e9nervation des poumons dNerva\u00ae est un syst\u00e8me innovant qui utilise un cath\u00e9ter pour traiter l\u2019hyperactivit\u00e9 bronchique au cours d\u2019une intervention appel\u00e9e la D\u00e9nervation Cibl\u00e9e des Poumons.

D\u00e9nervation Cibl\u00e9e des Poumons<\/p>\n

Interruption des signaux nerveux bronchiques<\/h2>\n <\/div>\n <\/div>\n\n
\n

La D\u00e9nervation Cibl\u00e9e des Poumons (DCP) est une intervention non chirurgicale, pratiqu\u00e9e en ambulatoire, qui consiste \u00e0 ins\u00e9rer le cath\u00e9ter dNerva dans un bronchoscope souple pour r\u00e9aliser une ablation circonf\u00e9rentielle compl\u00e8te dans la bronche souche de chaque poumon.
\nL\u2019ablation interrompt les signaux des nerfs pulmonaires vers le poumon, de mani\u00e8re permanente, r\u00e9duisant les cons\u00e9quences cliniques de l\u2019hyperactivit\u00e9 neuronale.<\/p>\n <\/div>\n \n <\/div>\n

\u00c9tape 1 : Positionner <\/h3>\n

Le cath\u00e9ter dNerva est introduit dans le canal op\u00e9rateur du bronchoscope et positionn\u00e9 dans les bronches souches. <\/p>\n <\/div>\n <\/div>\n\n \n

\nLa lib\u00e9ration naturelle d\u2019ac\u00e9tylcholine chez les patients atteints de BPCO a lieu lorsque le cerveau signale aux poumons, par l\u2019interm\u00e9diaire du nerf vague, de lib\u00e9rer l\u2019ac\u00e9tylcholine et met le syst\u00e8me pulmonaire en \u00e9tat d\u2019hyperactivit\u00e9 neuronale, qui est associ\u00e9e \u00e0 une inflammation chronique des voies respiratoires, et un accroissement des exacerbations et des sympt\u00f4mes
