1. A percutaneously deliverable device for treating a heart condition in a patient comprising:
- a first flange section having a plurality of flange segments angularly spaced about a longitudinal axis of the device, each flange segment of the first flange section comprising two prongs meeting at a junction; and
a second flange section having a plurality of flange segments angularly spaced about the longitudinal axis of the device, each flange segment of the second flange section comprising two elements meeting at a junction;
wherein each of the flange segments the each of the first and second flange sections are adapted to fold in the same direction upon the device being drawn into an opening of a percutaneous catheter to assume a collapsed configuration in which the junctions of the flange segments of the first flange section and of the second flange section are disposed distal to their corresponding prongs.

Abstract
Devices and methods to enhance the implantation, retreivability, or repositionability are provided. Embodiments of devices include pivotable sections providing the ability to maintain the device'"'"'s engagement with a delivery system during implantation where the deliver system approaches an opening of the septum at an angle. Embodiments of devices also include configurations that allow for improved retrieval into a delivery system in the event that a malfunction or a problem with the patients physiology is detected.

- 11. A reversibly collapsible device for treating a heart condition in a patient comprising a first flange section, a second flange section, and a longitudinal axis, wherein each of the first and second flange sections comprise a plurality of separate, adjacent segments, each segment comprising two prongs meeting at a junction, and is adapted to fold in the same axial direction upon the device being drawn into an opening of a percutaneous catheter to assume a collapsed configuration in which the junctions of the flange segments of the first flange section and of the second flange section are disposed distal to their corresponding prongs.

21. A percutaneous deliverable device adapted to be implanted into or retracted from, via a catheter, a patient'"'"'s atrial septum, comprising:
- a first annular flange section having a plurality of separate, adjacent flange segments, each flange segment of the first annular flange section comprising two prongs meeting at a junction; and
a second annular flange section having a plurality of separate, adjacent flange segments, each flange segment of the first annular flange section comprising two prongs meeting at a junction, wherein the flange segments of the first annular flange section and the flange segments of the second annular flange section are configured to collapse in the same direction upon retraction by said catheter to assume a collapsed configuration in which the junctions of the flange segments of the first flange section and of the second flange section are disposed distal to their corresponding prongs. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30)
