1. A system for treating a patient having a lung with an airway, the airway having an airway path prior to treatment, the system comprising:
- a bronchoscope having an elongate bronchoscope insertion tube, the insertion tube extending from a proximal working head to a distal end with a working channel therebetween, the distal end of the insertion tube configured to be inserted distally into an airway and having a scope oriented distally so as to acquire an image from within the airway distally of the distal end of the insertion tube;
an airway delivery catheter having a proximal end and a distal end with a delivery lumen therebetween, the delivery catheter receivable within the working channel of the bronchoscope, the distal end of the delivery catheter configured for advancement distally of the distal end of the insertion tube along the path of the airway; and
an implant including an elongate body extending between a proximal end and a distal end, the elongate body having a relatively straight configuration and a bent configuration, the elongate body in the straight configuration extending along an axis and advanceable within the delivery lumen into the airway so as to extend along the path of the airway, the elongate body of the implant configured to deploy from the straight configuration to the bent configuration within the airway so as to move the elongate body adjacent the distal end laterally from the axis and impart bending force on the airway such that the path of the airway bends.

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.

3. An implant for use in a system and for treating a patient, the patient having a lung with an airway, the airway having an airway path prior to treatment, the system including a bronchoscope having a working channel and a distally oriented viewing scope, the system also including a delivery catheter having a delivery lumen and advanceable from the working channel of the bronchoscope along the path of the airway, the implant comprising:
an elongate implantable spring element having a proximal end and a distal end, the spring element configured to be constrained into a relatively straight shape by the delivery catheter when disposed in the delivery lumen so as to extend along an axis, the spring element in the straight shape configured for advancement axially from the bronchoscope for delivery to the lung airway so as to extend axially along the path of the airway, the spring element biased to bend the spring element adjacent the distal end away from the axis when disposed in the airway unconstrained by the delivery catheter so as to impart bending force on the airway to cause the airway to be bent from the path. - View Dependent Claims (4, 5, 6)

7. A system for use with a bronchoscope and for treating a patient, the patient having a lung with lung tissue including an airway, the airway having an airway path prior to treatment, the bronchoscope having a working channel and a viewing scope for viewing distally within the airway, the system comprising:
-
a lung airway 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 advanced distally from the working channel of the bronchoscope along the path of the airway; an implantable device having an elongate body receivable within the delivery lumen and that is configured to be deployed from the delivery lumen into the airway of the lung of the patient, the elongate body configured to extend along an axis in a first configuration when disposed within the delivery catheter for axial insertion along the path of the airway, the elongate body of the implantable device configured to be reshaped from the first configuration to a second configuration within the airway, the elongate body in the second configuration configured to bend laterally away from the axis so as bend the path of the airway. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35)

36. A device for use in a system and for treating a patient having a lung with an airway lumen, the airway lumen having an airway path prior to treatment, the system including a bronchoscope having a working channel and a scope for viewing within the airway, the device comprising:
an elongate body having a proximal end and a distal end, the elongate body having a delivery configuration and a deployed configuration, the elongate body in the delivery configuration extending relatively straight along an axis and being adapted to be inserted within the working channel of the bronchoscope and advanced into the airway a lumen adjacent a region of lung tissue targeted for compression so as to extend along the airway path, the device configured for deployment from the delivery configuration to the deployed configuration within the airway lumen, the deployed configuration being more curved than the delivery configuration so that the elongate body, after deployment, bends the airway lumen away from the axis between the proximal and distal ends and locally compresses the region of lung tissue. - View Dependent Claims (37, 38)
