Torque Alleviating Intra-Airway Lung Volume Reduction Compressive Implant Structures

摘要

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.

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.
