Variable parietal/visceral pleural coupling
First Claim
Patent Images
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.

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.

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. - View Dependent Claims (14, 15, 16, 17, 18)
