1. A method of delivering an implantable device to a target site in a lung of a patient, the implantable device comprising:
(a) an elongated central body having a fixed axial length such that the elongated central body rigidly extends along a longitudinal axis;
(b) a distal end including a first anchor; and
(c) a proximal end including a second anchor;
the method comprising the steps of:
(a) aligning the first anchor to the target site while the implantable device is at least partially placed within a deployment device;
(b) deploying the first anchor by flexibly deforming the first anchor outwardly relative to the longitudinal axis such that the first anchor engages a first region of the target site of the lung;
(c) pulling the first anchor in a proximal direction towards the second anchor to reduce the volume of the lung; and
(d) severing an engagement feature, untying the engagement feature, or disconnecting magnets of the engagement feature to flexibly deform the second anchor outwardly relative to the longitudinal axis from a first position to a second position such that the second anchor engages a second region of the target site of the lung, wherein the second position is distal to the first position.
