Lung volume reduction devices, methods, and systems
First Claim
1. A method for treating a lung of a patient, the lung including a first airway axial region having a pre-deployment airway axis and a second airway axial region, the method comprising:
- compressing a lung tissue volume by urging the first airway axial region laterally away from the pre-deployment airway axis toward the second airway axial region using an implant system extending into the first and second airway axial regions.

Abstract
The invention provides improved medical devices, therapeutic treatment systems, and treatment methods for treatment of the lung. A lung volume reduction system includes an implantable device having an elongate body that is sized and shaped for delivery via the airway system to a lung airway of a patient. The implant is inserted and positioned while the implant is in a delivery configuration, and is reconfigured to a deployed configuration so as to locally compress adjacent tissue of the lung, with portions of the elongate body generally moving laterally within the airway so as to laterally compress lung tissue. A plurality of such implants will often be used to treat a lung of a patient.

10. An implant for treating a lung of a patient, the lung including a first airway axial region having an airway axis and a second airway axial region, the implant comprising:
-
a first elongate body portion having a first local axis; a second elongate body portion having a second local axis; an intermediate elongate body portion coupling the first elongate body portion to the second elongate body portion so that the implant is configured to deploy from a first configuration to a second configuration when the first elongate body portion extends axially along the first airway axial region and the second elongate body portion extends axially along the second airway axial region, the intermediate elongate body portion in the second configuration configured to bend so as to urge the first elongate body portion away from the airway axis and compress a lung tissue volume laterally between the first airway axial region and the second airway axial region, wherein the elongate body portions are included within a continuous elongate body, and wherein the elongate body is biased to bend from the first configuration to the second configuration so as to compress the lung tissue volume by urging a bearing surface of the elongate body laterally against an airway lumen surface so as to impose a bend in the airway system between the airway axial regions. - View Dependent Claims (11, 12, 13, 14)

15. A method for treating a lung of a patient, the lung including an airway system with a pre-deployment airway axis, the method comprising:
deploying an implant into an axial region of the airway having a first end and a second end so that a proximal end of the implant engages the first end of the axial region, so that a distal end of the implant engages the second end of the axial region, and so that the implant inwardly bends an airway wall portion into the airway between the first end of the axial region and the second end of the axial region laterally away from the pre-deployment airway axis. - View Dependent Claims (16)

17. An implant for treating a lung of a patient, the lung including an airway having a pre-deployment airway axis, the implant comprising:
an elongate body having a proximal end and a distal end, the implant having an insertion configuration suitable for insertion of the implant into an axial region of the airway so that a proximal end of the implant is adjacent the first end of the axial region and so that a distal end of the implant is adjacent the second end of the axial region, wherein the inserted implant is reconfigurable to a deployed configuration so as to move the airway laterally from the pre-deployment airway axis and impose an inward bend of an airway wall portion into the airway between the first end of the axial region and the second end of the axial region. - View Dependent Claims (18)
