Abstract
A pulmonary decompression device may be utilized to remove trapped air in the lung or lungs, thereby reducing the volume of diseased lung tissue. A lung reduction device may passively decompress the lung or lungs. In order for the system to be effective, an airtight seal between the parietal and visceral pleurae is required. Chemical pleurodesis is utilized for creating the seal.
Claims2
An implantable lung reduction device comprising:
- at least one first implantable member in fluid communication, at a predetermined site, within a lung of a patient, the at least one implantable member passing through a lung via a passage created therethrough;
- a sealing device for establishing an airtight seal between the at least one first implantable member and the lung;
- and
- a second member connected to the at least one first implantable member, the second member comprising an apparatus configured for actively drawing air directly from the lung of the patient to vent to an area external of the lung and preventing air from an area external of the lung from re-entering the lung through the implantable lung reduction device, the second member being secured external of the lung.
