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.

(canceled)
An implant for deployment within an airway of a lung of a patient for treating the lung of the patient, the implant comprising:
- a first portion having a first bearing surface and defining a first local axis, the first portion configured to engage the airway with the first bearing surface;
- a second portion coupled to the first portion, the second portion having a second bearing surface and defining a second local axis, the second portion configured to engage the airway with the second bearing surface;
- wherein, in a deployed configuration within the lung, the first portion presses against the airway in a direction lateral to the first local axis and toward the second portion, and the second portion presses against the airway in a direction lateral to the second local axis and toward the first portion, thereby compressing lung tissue between the first and second portions.
An implant for deployment within an airway of a lung of a patient for treating the lung of the patient, the implant comprising:
- an elongate body having a proximal end and a distal end;
- the elongate body configured to transition between a delivery configuration and a deployed configuration;
- and
- wherein the deployed configuration of the elongate body exerts force on the airway to fold the airway of the lung for locally compressing the lung;
- and
- wherein the elongate body is configured to elute a therapeutic drug.
A method for treating a patient having a lung with an airway, the method comprising
- deploying a lung implant to the airway of the lung, the implant comprising an elongate body having a proximal end and a distal end;
- wherein the elongate body of the deployed lung implant folds the airway of the lung;
- and
- wherein the elongate body of the lung implant is configured to elute a therapeutic drug.
