Patent Images
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; and
a second flange section having a plurality of flange segments angularly spaced about the longitudinal axis of the device;
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.

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.

31. 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; and a second annular flange section having a plurality of separate, adjacent flange segments, 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. - View Dependent Claims (32, 33, 34, 35, 36, 37, 38, 39, 40)
