Abstract
An intraluminal device and method of fixation of an intraluminal device to resist distal migration in a mammalian lumen or hollow organ that is subject to peristalsis, according to an aspect of the invention, includes spaced apart wall portions connected with a connector. The wall portions are configured to the size and shape of a portion of the lumen or hollow organ and the connector is configured to be positioned against a wall of the lumen or hollow organ. The intraluminal device is positioned in a mammalian lumen or hollow organ that is subject to peristalsis. The device is fixed in the lumen or hollow organ against distal migration, wherein tissue lining the lumen or hollow organ bridges over the connector. The device is explanted after tissue bridges over the connector including separating the connector from one or both of the wall portions and withdrawing the connector axially from the tissue bridging over the connector.
