1. A lung volume reduction system for enhancing a breathing efficiency of a patient with an airway, the system comprising:

  • an implantable device configured to impart a compression force on lung tissue, the implantable device including a proximal end and a distal end and further having a first configuration and a second configuration, the second configuration of the implantable device corresponding to a configuration of the implantable device pre-implantation or post-implantation, the second configuration comprises at least two helical sections with a transition section disposed between the at least two helical sections;

    wherein each of the at least two helical sections include a proximal portion and a distal portion, and wherein the proximal portion and the distal portion of each of the at least two helical sections are configured to compress lung tissue disposed between the proximal portion and the distal portion of each respective helical section.
