摘要： A method of planning a lung volume reduction treatment for a lung of a patient, the lung including an airway system having a plurality of branching airways, the method comprising identifying a target axial region of the airway system, the target axial region having a proximal end toward the esophagus and a distal end away from the esophagus with a length therebetween; selecting an implant in response to the length of the target axial region such that the implant has an elongate body with a body length greater than the length of the target axial region; such that a distal end of the selected implant can be advanced through the airway system toward the distal end of the target axial region; and such that the implant can be deployed within the target axial region so that the elongate body laterally compresses a portion of the lung. A system for use in a lung volume reduction treatment plan resulting from the method, comprises a catheter having a proximal end and a distal end with a lumen therebetween, the distal end of the catheter being advanceable through the airway system; and an implant receivable by the lumen, the implant comprising an elongate body having a distal portion and a proximal portion adjacent a proximal end of the implant, and a body length greater than the length of the target axial region, the distal portion being biased so that retraction of the distal end of the catheter from the distal portion of the implant can release the distal portion to engage the airway, the proximal end of the implant being advanceable distally relative to the airway while the catheter is withdrawn proximally from the proximal portion of the implant.
