PERCUTANEOUS SINGLE-PHASE SURGICAL PROCEDURE FOR CREATING A PNEUMOSTOMA TO TREAT CHRONIC OBSTRUCTIVE PULMONARY DISEASE
First Claim
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.

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.

17. A method for creating a stoma tract which passes through a chest wall, parietal membrane, pleural cavity and visceral membrane into a lung of a patient, wherein a surgical procedure comprises:
-
(a) percutaneously inserting a distal end of a surgical instrument through the chest wall, and parietal membrane into the pleural cavity; (b) passing the distal end of the surgical instrument across the pleural cavity; (c) inserting the distal end of the surgical instrument through the visceral membrane and into parenchymal tissue of the lung; (d) expanding an expandable portion of the surgical instrument adjacent the distal end of the surgical instrument within the lung thereby displacing parenchymal tissue of the lung and securing the distal end of the surgical instrument within the lung; (e) drawing the expandable portion of the surgical instrument toward the chest wall to approximate the visceral membrane and the parietal membrane sufficiently for pleurodesis to occur; (g) securing the surgical instrument to the chest wall for a period of time sufficient for a tract to heal around the surgical instrument; (h) causing the expandable body to contract; and (i) removing the surgical instrument from the stoma tract. - View Dependent Claims (18, 19, 20)
