Embodiment Construction

[0063] By way of background and in order to provide a context for the present invention, Figure 1A The respiratory system 10 is shown primarily within the chest cavity 11 . A description of the human body and physiology is provided to facilitate understanding of the invention. It will be understood by those skilled in the art that the scope and characteristics of the present invention are not limited by the provided human description. In addition, it should be understood that an individual's physical characteristics will vary due to a variety of factors which are not described herein. Respiratory system 10 includes trachea 12 which carries air from nose 8 or mouth 9 into primary right bronchi 14 and primary left bronchi 16 . Air enters the right lung 18 from the primary right bronchus 14 ; air enters the left lung 20 from the primary left bronchi 16 . Right lung 18 and left lung 20 together make up lung 19 . The left lung 20 consists of only two lobes, while the right lung ...

Abstract

Elongate implant structures can be introduced into an airway system to a target airway axial region, often to apply lateral bending and / or compression forces against the lung tissue from within the airways for an extended period of time. Structures or features of the implants may inhibit tissue reactions that might otherwise allow portions of the device to eventually traverse through the wall of the airway. The devices may enhance the area bearing laterally on the tissue of a surrounding airway lumen wall. Embodiments may have features which increase the device friction with the airway to allow the device to grip the surrounding airway as the device is deployed. An appropriate adhesive may be introduced around the device in the lung. Hydrophilic material may inhibit biofilm formation, or features which induce some tissue ingrowth (stimulation of tissue growth) may enhance implanted device supported.
