1. A surgical procedure used to create a pneumostoma which passes through a chest wall, parietal membrane, pleural cavity and visceral membrane into a lung of a patient, wherein the surgical procedure comprises:

  • (a) obtaining a pneumostomy instrument comprising an elongated body with an expandable body at a distal end thereof;

    (b) inserting the distal end of the pneumostomy instrument through the chest wall, and parietal membrane into the pleural cavity;

    (c) passing the distal end of the pneumostomy instrument across the pleural cavity;

    (d) inserting the distal end of the pneumostomy instrument through the visceral membrane and into parenchymal tissue of the lung;

    (e) expanding the expandable body within the parenchymal tissue of the lung thereby displacing parenchymal tissue and securing the distal end of the pneumostomy instrument within the lung;

    (f) pulling the pneumostomy instrument in the direction of a proximal end of the pneumostomy instrument to approximate the visceral membrane and the parietal membrane sufficiently for pleurodesis to occur;

    (g) securing the pneumostomy instrument to the chest wall while pleurodesis occurs between the visceral membrane and parietal membrane surrounding the pneumostomy instrument thereby sealing the pneumostoma from the pleural cavity;

    (h) reducing the expandable body;

    (i) removing the pneumostomy instrument from the pneumostoma.
