Intra/extra thoracic system for ameliorating a symptom of chronic obstructive pulmonary disease
First Claim
1. A system to alleviate a symptom of chronic obstructive pulmonary disease in a lung of a patient wherein the system comprises:
- at least one conduit having a first end which includes a first aperture, a second end which includes a second aperture, and a lumen which connects, in fluid communication, the first aperture and the second aperture;
an airway connection device which is adapted to connect the first end of the conduit to an artificial opening through a wall of a proximal airway wherein the proximal airway is a region of a trachea and a bronchus external to the lung;
a lung connection device which is adapted to connect the second end of the conduit to an artificial opening through a visceral membrane of the lung;
an access fitting connected to the conduit between the first end of the conduit and the second end of the conduit which can seal the lumen and is adapted to allow at least intermittent access to the lumen from outside the patient;
whereby the system is adapted to allow air to exit the lung via the artificial opening through the visceral membrane, enter the lumen through the second aperture, exit the lumen through the first aperture, and enter the proximal airway through the artificial opening in the wall of the proximal airway.

Abstract
A system to alleviate a symptom of chronic obstructive pulmonary disease in a lung of a patient by providing a ventilation bypass pathway which allows air to exit the lung via the bronchus or trachea. The system includes a conduit connected by an airway connection device to an artificial opening through a wall of a region of a trachea and a bronchus external to the lung. The other end of the conduit is connected by a lung connection device to an artificial opening through a visceral membrane of the lung. An access fitting is connected to the conduit between the first end of the conduit and the second end of the conduit and allows intermittent access to the lumen from outside the patient.

10. A system to alleviate a symptom of chronic obstructive pulmonary disease by creating a ventilation bypass between a lung of a patient and an airway of the patient wherein the airway is a region of a natural airway of the lower respiratory tract of the patient external to the lung, and wherein:
-
the system comprises a conduit having first and second ends and an access fitting connected to the conduit between the first end of the conduit and the second end of the conduit; the access fitting is adapted to allow at least intermittent access into the conduit from outside the patient; the first end of the conduit is adapted to be connected with the airway of the patient and sealed to a wall of the airway of the patient; the second end of the conduit is adapted to be connected with lung of a patient and is sealed to the lung of the patient; and the conduit is adapted to create a direct fluid communication between the lung of the patient and the airway of the patient along a path through the patient outside the lung and the airway of the patient thereby providing a ventilation bypass which permits air to exit the lung and enter the airway via the conduit. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)

19. A system to alleviate a symptom of chronic obstructive pulmonary disease in a lung of a patient by creating a ventilation bypass between the lung and an airway of the patient wherein the airway is a region of a natural airway of the lower respiratory tract of the patient external to the lung, and wherein the system comprises:
-
at least one conduit having a first end, a second end, and a lumen which connects, in fluid communication, the first end and the second end; a first connector which is adapted to connect the first end of the conduit to an artificial opening through a wall of the airway such that air may enter the airway through the wall of the airway via the lumen of the conduit; a second connector which is adapted to connect the second end of the conduit to an artificial opening in a visceral membrane of the lung such that air may leave the lung through the artificial opening in the visceral membrane of the lung via the lumen of the conduit; an access port connected to the conduit between the first end of the conduit and the second end of the conduit adapted to allow at least intermittent access to the lumen of the conduit from outside the patient. - View Dependent Claims (20)
