Abstract

A variable parietal/visceral pleural coupling may be utilized to create an air-tight seal in the pleural space between the parietal and visceral pleura. This coupling may be utilized to create a seal for other implantable devices.

Claims

1. A pleural cavity coupling comprising:

a first section that defines a first lumen having a first longitudinal axis, said first section adapted to be sealed to a parietal pleura;

a second section that defines a second lumen having a second longitudinal axis, said second section adapted to be sealed to the visceral pleura;

at least one of an adhesive and a suture adapted to secure the second section to the visceral pleura;

said first lumen of the first section in air-tight communication with the second lumen of the second section;

wherein the first section and the second section are moveable relative to each other and wherein the first lumen is sealed to the second lumen such that the communication between the first lumen and the second lumen remains sealed and air-tight as the first section moves relative to the second section; and

whereby the pleural cavity coupling is adapted to allow gasses to flow from a lung of a patient across the pleural cavity without causing a pneumothorax.

2. The coupling of claim 1 including:

the first and second sections defining a compression seal coupling in order to maintain the air-tight communication.

3. The pleural cavity coupling of claim 2 including:

said compression seal coupling includes an o-ring.

4. The pleural cavity coupling of claim 1, wherein:

said first section includes a first circular slot and a first rim;

said second section includes a second circular slot and a second rim;

wherein the first rim is received in the second circular slot and the second rim is received in the first circular slot; and

an o-ring located between the first rim and said second rim to maintain the air-tight communication.

5. The pleural cavity coupling of claim 1 adapted to establish a pleurodesis free connection between the parietal pleura and the visceral pleura.

6. The pleural cavity coupling of claim 1 wherein said first section and said second section together comprise a toroidal shape.

7. The pleural cavity coupling of claim 1 wherein said first section and said second section together comprise a rolling membrane.

8. The pleural cavity coupling of claim 1 wherein one of said first lumen and said second lumen is larger than the other.

9. The pleural cavity coupling of claim 1 wherein one of said first lumen and said second lumen is larger than the other in order to maintain the air-tight communication as the first section moves relative to the second section.

10. The pleural cavity coupling of claim 1 wherein said first section is in sliding engagement with the second section and the said first lumen is in sliding communication with the second lumen as the first section slides relative to the second section.

11. The pleural cavity coupling of claim 1 wherein said first lumen is in moving air-tight communication with the second lumen as at least one of the first section and the second section move relative to each other.

12. The pleural cavity coupling of claim 1 wherein said first section and said second section are adapted to be in sliding engagement with each other along the direction of the surface of at least one of the parietal pleura and the visceral pleura.

13. A pleural cavity coupling comprising:

a first section that defines a first lumen and the first section is adapted to be in contact with a parietal pleura;

a second section that defines a second lumen and the second section is adapted to be in contact with a visceral pleura;

at least one of an adhesive and a suture adapted to secure the second section to the visceral pleura;

said first lumen of the first section in air-tight communication with the second lumen of the second section;

the first section and the second section are moveable relative to each other such that the communication between the first lumen and the second lumen remains air-tight as the parietal pleura moves relative to the visceral pleura in order to establish a pleurodesis free connection to allow gasses to flow from a lung of a patient across the pleural cavity without causing a pneumothorax.

14. The pleural cavity coupling of claim 13, wherein said first lumen and said second lumen are adapted to create a seal for other devices that are to be implanted into the lung of a patient through the visceral pleura and the parietal pleura.

15. The pleural cavity coupling of claim 13, wherein the first section and second section together define a compression seal coupling.

16. The pleural cavity coupling of claim 15, further comprising an o-ring disposed between the first section and the second section.

17. The pleural cavity coupling of claim 13, wherein:

said first section includes a first circular slot and a first rim;

said second section includes a second circular slot and a second rim; and

wherein the first rim is received in the second circular slot and the second rim is received in the first circular slot.

18. The pleural cavity coupling of claim 17, further comprising an o-ring disposed between the first rim and the second rim.
