Minimally invasive lung volume reduction devices, methods, and systems

摘要

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.

主权项

1. 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 of the implant configured to engage a first portion of the airway with the first bearing surface; and the implant further comprising a second portion coupled to the first portion of the implant, the second portion of the implant having a second bearing surface and defining a second local axis, the second portion of the implant configured to engage a second portion of the airway with the second bearing surface, the second portion of the airway being axially spaced apart from the first portion of the airway; wherein, in a deployed configuration within the lung, the first portion of the implant presses against the first portion of the airway in a direction lateral to the first local axis and toward the second portion of the implant, and the second portion of the implant presses against the second portion of the airway in a direction lateral to the second local axis and toward the first portion of the implant, thereby compressing lung tissue between the first and second portions of the implant.
