Implantable artificial bronchus

An implantable artificial bronchus (IAB) is provided that is used for the treatment of chronic obstructive pulmonary diseases, such as pulmonary emphysema. The implantable artificial bronchus can be made with silicone or nitinol, and has a tapered cylindrical shape. Additional embodiments of this apparatus may be further associated with a one-way valve on the nozzle of the IAB.

Implantable artificial bronchus and use of an implantable artificial bronchus

An implantable artificial bronchus including a body having a proximal upper opening and a distal lower opening. The distal lower opening being in fluid communication with the proximal upper opening, and the body at least partially tapering along a length toward the distal lower opening. The body having a plurality of side openings configured to allow air to enter into and exit the implantable artificial bronchus through the body. A length of the body is greater than 4 times the size of a largest diameter of the body, and the diameter of the proximal upper opening is larger than a diameter of the distal lower opening.

A method of promoting lung disinsufflation including inserting a catheter into a bronchial passage of a patient's lung. The catheter contains an implantable artificial bronchus compressed within the catheter. The method further includes using the catheter to position the implantable artificial bronchus in the bronchial passage such that the implantable artificial bronchus extends across openings of a plurality of other bronchial passages and withdrawing the catheter from the bronchial passage to cause the implantable artificial bronchus to naturally expand and remain in the bronchial passage. The implantable artificial bronchus is configured to promote enlargement of the bronchial passage and allow air to exit from the plurality of other bronchial passages and into the implantable artificial bronchus through one or more of the plurality of side openings.
