1. A medical device for placement across aligned penetrations in adjacent tissue of a first luminal region of a body and a second region of the body to form a flow path therebetween, comprising:

  • an anchor comprising a woven filament braid with a central lumen having a first length in a radially constrained configuration, the anchor transitionable between the radially constrained configuration and a preformed configuration,the preformed configuration comprising a middle segment of the central lumen having a second length and a proximal end and a distal end of the central lumen flaring radially outward to form only one proximal flange structure along the proximal end and only one distal flange structure along the distal end,wherein the middle segment includes a substantially constant diameter which extends substantially an entire length between the proximal and distal flange structures,wherein the proximal flange structure includes a single tissue apposing surface adjacent to the middle segment and the distal flange structure includes a single tissue apposing surface adjacent to the middle segment to appose the adjacent tissue of the first luminal region and the second region along the middle segment,wherein, in the preformed configuration, the second length of the middle segment is at least 40% shorter than the first length of the central lumen in the radially constrained configuration, andwherein each of the proximal and distal flange structures has a diameter greater than twice a diameter of the middle segment and greater than the second length of the middle segment.
