Abstract: A device for implantation in a body may include a body defining a lumen. The body may have a first end and a second end, and the lumen may define a central axis. The body may include a first flexible flange having a first base portion and a first angled portion. The first base portion may be about perpendicular to the central axis and extend radially away from the first end. The body may further include a second flexible flange having a second base portion and a second angled portion. The second base portion may be about perpendicular to the central axis and extend radially away from the second end. The first and second angle portions may be generally angled toward each other. A loading device may be configured to load the device into a delivery device. The delivery device may be configured to delivery and deploy the device.
