1. A percutaneously deliverable device for treating a heart condition in an atrial septum of a patient comprising:
- a first flange section having a plurality of flange segments spaced about a longitudinal axis of the device; and
a second flange section comprising a plurality of flange segments, wherein the first and second flange sections are configured to be positioned on opposing sides of the atrial septum,wherein a proximal portion of each of the plurality of flange segments of the first flange section has a pivotable section, the pivotable sections joining to form a proximal hub, wherein the pivotable sections allow for the proximal hub to be curved, bent, turned, or twisted relative to the first flange section as the first and second flange sections are deployed across and conform to the atrial septum.

Abstract
Devices and methods to enhance the implantation, retrievability, 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.

9. A method for percutaneously delivering a device for treating a heart condition, the method comprising:
-
releasably engaging the device with a delivery catheter; advancing the device through the delivery catheter to a septal wall of a heart of a patient, a proximal portion of the device comprising a pivotable section; positioning a first flange and a second flange of the device on opposing sides of septal wall; and pivoting the pivotable section such that the pivotable section is angled away from a longitudinal axis of the device while the first and second flanges are deployed across and conform to the septal wall. - View Dependent Claims (10, 11, 12)

13. A percutaneously deliverable device for treating a heart condition in an atrial septum of a patient comprising:
-
a first flange section having a plurality of flange segments spaced about a longitudinal axis of the device; a second flange section comprising a plurality of flange segments, wherein the first and second flange sections are configured to be positioned on opposing sides of the atrial septum; and a pivotable end connecting to a proximal end of the first flange, wherein the pivotable end of the first flange section is adapted to have a non-zero angle up to 180 degree rotational displacement angle relative to the longitudinal axis of the device.
