Medical devices and procedures for assessing a lung and treating chronic obstructive pulmonary disease

Dispositifs médicaux et procédures permettant l'évaluation d'un poumon et le traitement de la bronchopeumathie chronique obstructive

Abstract

A pulmonary pleural stabilizer (1102) holds the visceral pleura (1101) of the lung during surgical procedures accessing the lung of a patient directly through the chest wall. The stabilizer allows the lung to be opened while another device (1204) is inserted and sealed to the lung. A localized pleurodesis may be created utilizing a chemical component to create an acute adhesion and a mechanical component to create a chronic adhesion. Once a device is inserted into the lung, a pleura anastomosis reinforcement device may be positioned adjacent the device to provide structural reinforcement and prevent damage to the pleura. A visceral pleura ring connector may also be positioned around the pleura and the device to receive and secure the device. A mechanical device or chemical process ensures that air flows freely through the implanted device. The medical devices and procedures provide treatments for chronic obstructive pulmonary disease and emphysema.
La présente invention concerne un stabilisateur de la plèvre viscérale permettant de maintenir la plèvre viscérale lors d'interventions chirurgicales d'accès au poumon d'un patient directement via la paroi de la cage thoracique. Le stabilisateur permet l'ouverture du poumon tandis qu'un autre dispositif est introduit et fixé au poumon. Une pleurodèse localisée peut être créée au moyen d'un composé chimique pour produire une adhérence aiguë et un composant mécanique pour produire une adhérence chronique. Une fois le dispositif introduit dans le poumon, un dispositif de renfort d'anastomose de la plèvre peut être positionné adjacent au dispositif pour assurer un renfort structurel et empêcher l'endommagement de la plèvre. Un raccord d'anneau de plèvre viscérale peut également être positionné autour de la plèvre et le dispositif pour recevoir et fixer le dispositif. Un dispositif mécanique ou un procédé chimique assure la libre circulation de l'air via le dispositif implanté. Les dispositifs médicaux et les interventions fournissent des traitements pour la bronchopeumathie chronique obstructive et l'emphysème.
