Abstract

L'invention concerne un dispositif et un procédé de traitement des tubes bronchiques collabés, chez des patients atteints de maladie respiratoire obstructive chronique et d'asthme. Le dispositif comprend un élément allongé (10), pourvu d'un élément chauffant (12, 14), constitué d'un ou plusieurs éléments d'alimentation énergétique (18). Le procédé consiste à chauffer le tube bronchique pour qu'au moins une partie des réticulations du collagène de la paroi de la lumière se délie/s'ouvre, formant ainsi de nouvelles réticulations après que les fibres de collagène se sont repositionnées. Cette procédure permet de renforcer efficacement l'intégrité structurelle de ladite paroi, et donc de prévenir tout collabage de la lumière.
