Abstract

A method for repairing pulmonary air leaks in a lung residing in a chest cavity and having an intake air stream and an outer surface is disclosed. An exemplary method comprises: introducing a first component of a biphasic sealant component as a liquid into the intake air stream of the damaged lung; ensuring that there is a pressure differential between the intake air stream and the outer surface of the lung; and introducing a second component of a biphasic sealant component into the chest cavity. The first sealant component collects at the air leak site and forms a sealant in combination with the second sealant component.

Claims

1. A method for repairing pulmonary air leaks in a lung residing in a chest cavity of a patient in need thereof and having an intake air stream and an outer surface of the lung comprising:

introducing a first biphasic sealant component as a liquid, an aerosol, or a particulate stream into the intake air stream;

ensuring that there is a pressure differential between the intake air stream and the outer surface of the lung by exposing the lung to negative pressure via a chest tube that is on suction;

introducing a second biphasic sealant component into the chest cavity, whereby the second biphasic sealant component upon contact with the first sealant component forms a sealant.

2. The method of claim 1, wherein the first biphasic sealant component is nebulized and has a particle size of approximately 1 micron.

3. The method of claim 1, wherein the first and second biphasic sealant components form fibrin glue when combined.

4. The method of claim 1, wherein the first biphasic sealant is PLGA and the second biphasic sealant is gelatin.

5. The method of claim 1, wherein said second biphasic sealant component is introduced into the chest cavity by a tube.

6. The method of claim 1, wherein the first and second biphasic sealant components form a bioabsorbable sealant when combined.

7. The method of claim 1, wherein the first and second biphasic sealant components form a biocompatible sealant when combined.

8. A system for repairing pulmonary air leaks in a lung residing in a chest cavity of a patient in need thereof and having an intake air stream and an outer surface of the lung comprising:

a selectively curable sealant capable of being introduced into the lung by inhalation;

means for introducing the sealant as a liquid, an aerosol, or a particulate stream into the lung by inhalation;

and a chest tube that is on suction for ensuring a pressure differential between the intake air stream and the outer surface of the lung.

9. The system of claim 8 wherein the selectively curable sealant is a biphasic sealant and further comprising:

a second sealant component; and

means for introducing said second sealant component to the outer surface of the lung.

10. The system of claim 9 wherein the selectively curable sealant has a particle size of approximately 1 micron.

11. The system of claim 9 wherein said means for introducing said second sealant component include a tube inserted into the chest cavity.

12. The system of claim 8 wherein said selectively curable sealant is cured by light and further comprising:

means for introducing light to the outer surface of the lung.

13. A system for repairing pulmonary air leaks in a lung residing in a chest cavity of a patient in need thereof and having an intake air stream and an outer surface of the lung comprising:

a first biphasic sealant component introduced as a liquid, an aerosol, or a particulate stream into the intake air stream;

a second biphasic sealant component introduced into the chest cavity, which forms a sealant when combined with the first sealant component;

and a chest tube that is on suction for ensuring a pressure differential between the intake air stream and the outer surface of the lung.

14. The system of claim 13 wherein the first biphasic sealant component is PLGA and the second biphasic sealant component is gelatin.

15. The system of claim 13, wherein the first and second biphasic sealant components form a bioabsorbable sealant when combined.

16. The system of claim 13, wherein the first and second biphasic sealant components form a biocompatible sealant when combined.
