1. A system for treating a patient having a lung with an airway and a portion of the lung offset eccentrically from the airway, the system comprising:
- a delivery catheter having a proximal end and a distal end with a delivery lumen therebetween, the distal end of the delivery catheter configured to be inserted distally into the airway;
an implant having a proximal end and a distal end and an elongate body therebetween, the implant configured to be delivered to the airway in a delivery configuration in the delivery lumen of the delivery catheter, the implant further configured to be deployed within the airway with the elongate body extending along a region of the airway from the delivery configuration to a deployed configuration, the elongate body of the deployed configuration of the implant configured to selectively compress the portion of the lung offset eccentrically from the airway and disposed between the proximal end and the distal end of the implant.

Abstract
A lung volume reduction system is disclosed comprising an implantable device adapted to be delivered to a lung airway of a patient in a delivery configuration and to change to a deployed configuration to bend the lung airway. The invention also discloses a method of bending a lung airway of a patient comprising inserting a device into the airway in a delivery configuration and bending the device into a deployed configuration, thereby bending the airway.

14. A method for treating a patient having a lung with an airway and a lung portion offset eccentrically from the airway, the method comprising:
-
delivering an implant in a delivery configuration, within a delivery lumen of a delivery catheter, into the airway of the lung, the implant having a proximal end and a distal end and an elongate body therebetween; deploying the implant from the delivery lumen of the delivery catheter to the portion of the lung, the implant being deployed from the delivery configuration to a deployed configuration within the lung; and wherein the elongate body of the deployed implant extends along a region of the airway and wherein the elongate body of the deployed implant selectively compresses the portion of the lung offset eccentrically from the airway between the proximal end and the distal end of the implant. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27)

28. A method for treating a patient having a lung with an airway, the method comprising:
deploying an implant with an elongate body within the airway of the lung from a delivery configuration to a deployed configuration, the elongate body of the deployed implant extending along a region of the airway and configured to locally compress a portion of the lung offset eccentrically from the airway and disposed directly between a proximal end and a distal end of the implant; and
the deployed implant allowing air or fluid to pass through the airway therepast.- View Dependent Claims (29, 30, 31)
