Abstract
The invention provides methods and devices for creating a localized pleurodesis between the thoracic wall and the lung such that a ventilation bypass conduit may be introduced into the lung through the thoracic wall and visceral membrane without causing a pneumothorax. A catheter or implantable device delivers the pleurodesis agent to the pleural cavity.
Claims18
A method to introduce a conduit through a parietal membrane and a visceral membrane and into a lung of a subject without allowing air to enter an intrapleural space around the lung, the method comprising:
- (a) introducing an implantable medical device which comprises a chemical agent into the intrapleural space;
- (b) allowing the release of the chemical agent from the implantable medical device into a localized area of the intrapleural space such that the chemical agent creates a localized adhesion between the parietal membrane and visceral membrane within the localized area;
- and
- (c) subsequent to steps (a) and (b) introducing the conduit from a position external to the lung into tissue of the lung through the parietal membrane and the visceral membrane within the localized adhesion.
A method for treating a lung of a patient using a ventilation bypass system comprising a conduit having a distal end for insertion in the lung through a thoracic wall, a parietal membrane and a visceral membrane wherein the method comprises:
- (a) inserting an implantable disk including a pleurodesis agent into an intrapleural space;
- (b) delivering the pleurodesis agent to a localized area of the intrapleural space using the implantable disk so as to create a localized pleurodesis between the parietal membrane and the visceral membrane;
- (c) creating an opening in the thoracic wall, parietal membrane and visceral membrane through the localized pleurodesis;
- and
- (d) inserting the distal end of the conduit into the lung through the opening in the thoracic wall, parietal membrane and visceral membrane through the localized pleurodesis.
