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 having an elongate body including a proximal end and a distal end, the implantable device 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 comprising at least one helical section;
wherein the at least one helical section includes a proximal portion, a distal portion, and a helical axis, the proximal portion and the distal portion of the at least one helical section configured to compress lung tissue disposed between the proximal portion and the distal portion;
wherein the elongate body transitions from the at least one helical section to a stand-off proximal tail at the proximal end of the elongate body, the stand-off proximal tail comprising a distal portion adjacent to and bending from the at least one helical section, a proximal portion, and a bend disposed between the distal portion and the proximal portion.

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.

20. A method of enhancing breathing efficiency of a patient with a lung having an airway, the method comprising:
-
providing an implant, the implant having an elongate body including a proximal end and a distal end; advancing the implant distally through the airway toward a target site of the lung of the patient while the implant is in a delivery configuration; deploying the implant at the target site of the lung by transitioning the implant from the delivery configuration to a deployed configuration, the deployed configuration of the implant comprising at least one helical section; wherein the at least one helical section includes a proximal portion, a distal portion and a helical axis; and
wherein the proximal portion and the distal portion of the at least one helical section are configured to compress lung tissue disposed between the proximal portion and the distal portion at the target site; andwherein the elongate body transitions from the at least one helical section to a stand-off proximal tail at the proximal end of the elongate body, the stand-off proximal tail comprising a distal portion adjacent to and bending from the at least one helical section, a proximal portion, and a bend disposed between the distal portion and the proximal portion.
