Abstract

A mechanical device and/or chemical process is utilized to maintain luminal patency in conduits or other devices implanted in the lung or lungs of a patient. The mechanical device and/or chemical process ensures that air flows freely through a conduit implanted through an anastomosis into a lung. The device is suitable for use in conjunction with ventilation bypass treatments for chronic obstructive pulmonary disease.

Claims

1. A system to create an opening in parenchymal tissue of the lung and maintain patency comprising:

a first device with a lumen and an opening communicating with the lumen, wherein said opening of said device is adapted to be positioned one of adjacent to and in the parenchymal tissue;

a second device to be used in combination with the first device, wherein said second device is associated with the opening of said first device;

wherein said second device is a surgical instrument with a sharp tip; and

wherein said second device can create the opening in the parenchymal tissue.

2. The system of claim 1 wherein said second device can fit into the lumen.

3. The system of claim 1 wherein said second device can fit into the lumen and be deployed adjacent to said opening of said lumen.

4. The system of claim 1 wherein said second device is adapted to be moved relative to the parenchyma tissue in order to interfere with at least one of tissue buildup and secretional buildup.

5. The system of claim 1 wherein said tip of said second device is one of formed with and attached to the opening in the lumen.

6. The system of claim 1 wherein said first device is a conduit that is adapted to provide a pathway through the pleura of the lung.

7. The system of claim 1 wherein said first device is a conduit that is adapted to provide a pathway to the parenchymal tissue of the lung.

8. The system of claim 1 wherein said first device is a conduit that is adapted to provide collateral ventilation to the lung.

9. The system of claim 1 wherein said sharp tip of said second device allows the lumen to remain patent through the use of the first device.

10. The system of claim 1 wherein said tip is serrated.

11. The system of claim 1 wherein said second device is a trocar with said sharp tip.

12. A method to create an opening in parenchymal tissue of the lung and maintain patency comprising the steps of:

using a first device to create an opening through the chest wall so that the opening is located one of adjacent and in parenchymal tissue of the lung, wherein said first device includes a lumen and an opening communicating with the lumen; and

using a second device in combination with the first device, which second device has a sharp tip, to create the opening in the parenchymal tissue of the lung and to maintain patency.

13. The method of claim 12 wherein said second device using step includes placing the second device into the lumen of the first device in order to create the opening in parenchymal tissue of the lung.

14. The method of claim 12 wherein said second device using step includes deploying the sharp tip of the second device adjacent to the opening in the first device.

15. The method of claim 12 wherein said second device moving step includes moving said second device relative to the parenchymal tissue in order to create the opening in the parenchymal tissue.

16. The method of claim 12 wherein said second device moving step includes moving said second device relative to the first device in order to create the opening in the parenchymal tissue.

17. The method of claim 12 wherein said second device using device includes using a trocar with the sharp tip relative to the opening in the first device in order to create the opening in the parenchymal tissue.

18. A system to create an opening in parenchymal tissue of the lung and maintain patency comprising:

a first device with a lumen and an opening communicating with the lumen, wherein said opening of said device is adapted to be positioned one of adjacent to and in the parenchymal tissue;

a second device to be used in combination with and received inside of the lumen of the first device, wherein said second device is associated with the opening of said first device;

wherein said second device is a surgical instrument with a sharp tip; and

wherein said second device can move relative to the first device in order to create the opening in the parenchymal tissue.
