A pneumostoma management system for maintaining the patency of a pneumostoma while controlling the flow of material through the pneumostoma. The pneumostoma management system includes a two-part pneumostoma management device and associated insertion and removal tools. The pneumostoma management device includes a pneumostoma vent and a chest mount for positioning and securing the vent into a pneumostoma. The pneumostoma vent includes a hydrophobic filter and/or a one-way valve.

a coupling that can releasably engage the proximal end of the vent, and

an aperture through the chest mount wherein the aperture is larger in diameter than the distal end of the vent, so that the aperture permits the distal end of the vent to be fit through the aperture into the pneumostoma, but smaller in diameter than the proximal end of the vent to prevent the proximal end of the vent from passing through the aperture into the pneumostoma.

whereby the distal end of the vent is adapted to be selectively positioned within the lung, while the proximal end of the vent is releasably secured to the chest mount and prevented from passing into the pneumostoma.

2. The medical device of claim 1, wherein the aperture passes centrally through the chest mount.

3. The medical device of claim 1, wherein the vent comprises a cap connected to the proximal end of the tubular body and wherein the cap includes a filter.

4. The medical device of claim 1, wherein the vent comprises a cap connected to the proximal end of the tubular body wherein each component of the cap is too large to pass completely through the aperture such that the aperture prevents each component of the cap from passing into the pneumostoma.

5. The medical device of claim 1, wherein the vent comprises a cap connected to the proximal end of the tubular body wherein the cap includes a filter and wherein each component of the cap, including the filter, is too large to pass completely through the aperture such that the aperture prevents each component of the vent cap from passing into the pneumostoma.

6. The medical device of claim 1, wherein the chest mount includes a recess adjacent the aperture and the proximal end of the vent is adapted to fit within the recess such that it is substantially flush with the chest mount when the vent is positioned in the pneumostoma.

7. The medical device of claim 1, wherein the vent comprises a cap connected to the proximal end of the tubular body and wherein the proximal end of the tubular body is larger than the diameter of the aperture so that the aperture prevents the proximal end of the tubular body from passing into the pneumostoma.

8. The medical device of claim 1, wherein the chest mount is adapted to remain secured to the chest of the patient when the vent is removed.

9. The medical device of claim 1, wherein the coupling of the chest mount includes a recess adjacent the aperture and the proximal end of the vent is adapted to fit within the recess substantially flush with the chest mount.

10. The medical device of claim 1, wherein the chest mount comprises:

an aperture plate of a first material which defines the aperture; and

a flange of a second more elastic material having the adhesive surface for releasably securing the chest mount to the chest of the patient wherein the flange is larger than the aperture and wherein the flange is adapted to conform to the chest of the patient.

11. The medical device of claim 1, wherein the chest mount is compliant and can follow the surface of the skin of a patient.

12. The medical device of claim 1, wherein the chest mount is adapted to be secured to a patient for about a week before being replaced.

13. The medical device of claim 1, wherein the vent is adapted to be secure to the chest mount for about a day before being replaced.

14. The medical device of claim 1, wherein the chest mount is conical in shape.

15. The medical device of claim 1 wherein the chest mount is a thin flexible disc.

16. The medical device of claim 1, wherein the chest mount is substantially flush with the skin of a patient.

17. The medical device of claim 1, wherein the chest mount is dome shaped.

18. A medical device used to allow gases to exit a lung of a patient through a passage which passes through a chest wall into the lung through a region of pleurodesis between visceral and parietal membranes surrounding the lung, wherein the medical device comprises;

a chest mount which comprises,

a surface adapted to releasably secure the chest mount to the chest of the patient,

an aperture through the chest mount; and

a vent adapted to be inserted into the chest through the passage which passes through the chest wall into the lung to permit gases to exit a lung of the patient, wherein the vent comprises,

a distal opening in a distal end of the vent adapted to admit gases from the lung,

a proximal opening in a proximal end of the vent adapted to allow gases from the lung to exit the vent outside of the chest of the patient,

a contact surface that can releasably engage the chest mount,

a tubular body adapted to slide into the passage; and

wherein the distal end of the vent is smaller in diameter than the aperture, so that the aperture permits the distal end of the vent to be fit through the aperture into the passage, but the proximal end of the vent is larger in diameter than the aperture to prevent the proximal end of the vent from passing through the aperture into the passage;

whereby the distal end of the vent is adapted to be selectively positioned within the lung while the proximal end of the vent is releasably secured to the chest mount and prevented from passing into the passage.

19. The medical device of claim 18, wherein the aperture passes centrally through the chest mount.

20. The medical device of claim 18, wherein the vent comprises a cap connected to the proximal end of the tubular body and wherein the cap includes a filter.

21. The medical device of claim 18, wherein the vent comprises a cap connected to the proximal end of the tubular body, wherein each component of the cap is too large to pass completely through the aperture such that the aperture prevents each component of the cap from passing into the passage.
