Patent application number | Description | Published |
20090012626 | MINIMALLY INVASIVE LUNG VOLUME REDUCTION DEVICES, METHODS, AND SYSTEMS - A lung volume reduction system is disclosed comprising an implantable device adapted to be delivered to a lung airway of a patient in a delivery configuration and to change to a deployed configuration to bend the lung airway. The invention also discloses a method of bending a lung airway of a patient comprising inserting a device into the airway in a delivery configuration and bending the device into a deployed configuration, thereby bending the airway. | 01-08-2009 |
20100100196 | Elongated Lung Volume Reduction Devices, Methods, and Systems - A lung volume reduction system is disclosed comprising an elongate implantable device adapted to be delivered to a lung airway of a patient in a delivery configuration and to change to a deployed configuration to compress lung tissue. The implant may be longer in axial length than an axial length of the target axial region in which it is deployed. Deployment may involve allowing an end of the implant to move relative to surrounding tissue while the implant is progressively deployed. | 04-22-2010 |
20100305715 | Cross-Sectional Modification During Deployment of an Elongate Lung Volume Reduction Device - Elongate implant structures can be introduced into an airway system to a target airway axial region, often to apply lateral bending and/or compression forces against the lung tissue from within the airways for an extended period of time. Structures or features of the implants may inhibit tissue reactions that might otherwise allow portions of the device to eventually traverse through the wall of the airway. The devices may enhance the area bearing laterally on the tissue of a surrounding airway lumen wall. Embodiments may have features which increase the device friction with the airway to allow the device to grip the surrounding airway as the device is deployed. An appropriate adhesive may be introduced around the device in the lung. Hydrophilic material may inhibit biofilm formation, or features which induce some tissue ingrowth (stimulation of tissue growth) may enhance implanted device supported. | 12-02-2010 |

The invention also discloses a method of bending a lung airway of a patient comprising inserting a device into the airway in a delivery configuration and bending the device into a deployed configuration, thereby bending the airway. | 12-18-2014 |
20150051709 | Torque Alleviating Intra-Airway Lung Volume Reduction Compressive Implant Structures - 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. | 02-19-2015 |
