Elongated Lung Volume Reduction Devices, Methods, and Systems

摘要

A lung volume reduction system is disclosed comprising an elongate 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 compress lung tissue. The implant may be longer in axial length than an axial length of the target axial region in which it is deployed. Deployment may involve allowing an end of the implant to move relative to surrounding tissue while the implant is progressively deployed.

主权项

1. A method for treating a lung of a patient, the lung including an airway system having a plurality of branching airways, the method comprising:
advancing an implant through the airway system, the implant having an elongate length; deploying a distal portion of the implant within the airway system so that the distal portion engages an airway; and progressively deploying the implant proximally of the distal portion while a proximal end of the implant advances distally relative to the adjacent airway system so as to inhibit axial loading between the implant and the airway when the implant compresses lung tissue along the length of the implant.
