A long term oxygen therapy system having an oxygen supply directly linked with a patient's lung or lungs may be utilized to more efficiently treat hypoxia caused by chronic obstructive pulmonary disease such as emphysema and chronic bronchitis. The system includes an oxygen source, one or more valves and fluid carrying conduits. The fluid carrying conduits link the oxygen source to diseased sites within the patient's lungs. A collateral ventilation bypass trap system directly linked with a patient's lung or lungs may be utilized to increase the expiratory flow from the diseased lung or lungs, thereby treating another aspect of chronic obstructive pulmonary disease. The system includes a trap, a filter/one-way valve and an air carrying conduit. In various embodiments, the system may be intrathoracic, extrathoracic or a combination thereof. A pulmonary decompression device may also 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 and various devices and/or drugs, agents and/or compounds may be utilized to accelerate wound healing in thoracic anastomosis applications.

A pacing lead for implantation in the pericardial space includes an elongated lead body, a compression fixation element, and at least one electrode on either the lead body or the fixation element. The fixation element defines a resilient structure, and is positioned and dimensioned so that when the lead is disposed in the pericardial space, the resilient fixation element is compressed between the parietal and visceral pericardium, thereby biasing the electrode against the myocardium and providing positional stabilization to the lead. Further positional stability may be provided mechanically with structures enabling the application of adhesive or with fixation screw or tine elements.

Techniques for treating visceral or parietal membrane and tissue defects include the application of a collagen biomatrix to the defect to repair and regenerate a visceral or parietal membrane, for example in patients suffering tissue defects or undergoing visceral or parietal surgical treatment. Such approaches avoid persistent tissue leaks and their consequences such as fluid leaks and air leaks. The use of collagen biomatrix, optionally in conjunction with a fibrin sealant, an anti-adhesive, or both, can minimize tissue leaks or fluid leaks in injured patients suffering tissue defects or subjects undergoing surgery such as visceral or parietal resections and other operations.

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.
