Torque alleviating intra-airway lung volume reduction compressive implant structures
First Claim
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.

Abstract
A device for enhancing the breathing efficiency of a patient is provided. The implantable device may include a deployed configuration with one or more helical sections with proximal end in a stand-off proximal end configuration. The stand-off proximal end configuration may reduce migration of the deployed device and may preserve implant tissue compression. Alternative configurations may include two or more helical sections with a transition section disposed between the two or more helical sections. A device may include a right-handed helical section and a left-handed helical section and the transition section comprises a switchback transition section. The switchback section may provide greater control of the device during deployment by limiting recoiling forces of a device comprising a spring material. The deployed device may compress the lung to increase a gas filling resistance of the compressed portion of the lung, and/or increase tension and elastic recoil in other portions of the lung.
