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.
Claims20
A pleural cavity coupling comprising:
- a first section that defines a first lumen and said first section is sealed to the parietal pleura;
- a second section that defines a second lumen and said second section is sealed 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 sealed and air-tight as the parietal pleura moves relative to the visceral pleura.

A pleural cavity coupling comprising:
- a first section that defines a first lumen and the first section is adapted to be in contact with the parietal pleura;
- a second section that defines a second lumen and the second section is adapted to be in contact with the visceral pleura;
- at least one of an adhesive and a suture 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 the lung of a patient.
