Percutaneous single-phase surgical procedure for creating a pneumostoma to treat chronic obstructive pulmonary disease

Abstract

A percutaneous single-phase surgical procedure is disclosed for creating a pneumostoma to treat chronic obstructive pulmonary disease. A pneumostomy instrument is introduced percutaneously through the thoracic wall, parietal membrane, visceral membrane and into the parenchymal tissue of the lung. The pneumostomy instrument crosses the pleural cavity between the parietal membrane and visceral membrane there being no pleurodesis between the membranes prior to passage of the pneumostomy instrument. A pneumoplasty device at the distal end of the pneumostomy instrument displaces and engages the parenchymal tissue of the lung and the pneumostomy instrument is used to secure the lung and visceral membrane in contact with the parietal membrane and chest wall. The pneumostomy instrument is left in place while a pneumostoma tract heals and pleurodesis occurs between the pleural membranes surrounding the pneumostomy instrument.

Benefits of technology

[0036]In view of the disadvantages of the state of the art, Applicants have developed a method for treating COPD in which an artificial passageway is made through the chest wall into the lung. An anastomosis is formed between the artificial passageway and the lung by creating a seal, adhesion and/or pleurodesis between the visceral and parietal membranes surrounding the passageway as it enters the lung. The seal, adhesion and/or pl

Problems solved by technology

However an additional ten million adults have evidence of impaired lung function indicating that COPD may be significantly underdiagnosed.

This increases the work of exhaling and leads to hyperinflation of the lung.

When the lungs become hyperinflated, forced expiration cannot reduce the residual volume of the lungs because the force exerted to empty the lungs collapses the small airways and blocks air from being exhaled.

With continued exposure to cigarettes or noxious particles, the disease progresses and individuals with COPD in
