Removable lung reduction devices, systems, and methods
First Claim
1. A method of moving a device in an air passageway, wherein the device comprises a flexible frame with at least one frame support, the frame support further comprising at least one fixation projection configured to extend inwardly into the air passageway while deployed, wherein the at least one fixation projection is configured to release from the air passageway when pulled in a proximal direction, the method of moving the device comprising:
- advancing a catheter through a trachea and into the air passageway, the catheter having at least one internal lumen;
advancing a retractor through the internal lumen of the catheter to the device;
grasping a portion of the device with the retractor;
collapsing the device to free the device from deployment in the air passageway; and
advancing the catheter over at least a portion of the retractor and a proximal end of the device; and
withdrawing the catheter from the air passageway and trachea.

Abstract
An air passageway obstruction device includes a frame structure and a flexible membrane overlying the frame structure. The frame structure is collapsible upon advancement of the device into the air passageway, expandable into a rigid structure upon deploying in the air passageway and recollapsible upon removal from the air passageway. The flexible membrane obstructs inhaled air flow into a lung portion communicating with the air passageway. The device may be removed after deployment in an air passageway by recollapsing the device and pulling the device proximally through a catheter.

8. A kit for moving a device, the device being collapsible and dimensioned for insertion into an air passageway communicating with a portion of a lung to be treated, the device being movable from a collapsed position to a deployed position, the device further comprising at least one anchor configured to engage the air passageway when the device is in a deployed position, and wherein the at least one anchor is configured to release from the air passageway when pulled in a proximal direction, and wherein the kit comprises:
-
a catheter having an internal lumen and being dimensioned to fit within the air passageway; and a retractor configured to fit within the internal lumen of the catheter and comprising at a distal end a member for engaging the device to remove the device from the air passageway. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17, 18)
