1. A device for implanting in an opening is a septal wall in a heart of a patient, the device comprising:
- a core segment defining a passage through which fluid can flow after implantation of the device, the passage comprising a diameter larger than about 5 mm, the flow being from one side of the septal wall to another side of the septal wall, the core segment having a first diameter when deployed;
a first annular flange contiguous with the core segment; and
a second annular flange contiguous with the core segment,wherein the device is collapsible, enabling the core segment to have a second diameter less than the first diameter thereby enabling percutaneous delivery of the device to the heart of the patient, andwherein the core segment comprises a non-braided substantially open mesh.
