Devices, systems and methods to treat heart failure
First Claim
1. A device for treating a heart condition in a patient, said device implanted into the atrial septum of said patient'"'"'s heart, said device comprising:
- a body element comprising;
a core segment having an axial length and defining a passage;
a first annular flange comprising a plurality of flange segments having substantially similar lengths and adapted to engage a first surface of said atrial septum;
a second annular flange comprising a plurality of flange segments having substantially similar lengths and adapted to engage a second surface of said atrial septum; and
a third annular flange disposed between the first annular flange and the second annular flange along the core segment axial length, the third annular flange comprising a plurality of flange segments having substantially similar lengths and less than the lengths of said plurality of flange segments of said second annular flange, said plurality of flange segments of said third annular flange also adapted to engage said second surface of said atrial septum;
wherein the first, second, and third annular flange are at least one of attached to and extending from the core segment, and wherein the core segment has a first diameter when deployed and wherein the core segment is collapsible, enabling the core segment to have a second diameter less than the first diameter thereby enabling percutaneous delivery.

Abstract
Several unique intracardiac pressure vents, placement catheters, methods of placement and methods of treating heart failure are presented. The intracardiac pressure vents presented allow sufficient flow from the left atrium to the right atrium to relieve elevated left atrial pressure and resulting patient symptoms but also limit the amount of flow from the right atrium to the left atrium to minimize the potential for thrombus or other embolic material from entering the arterial circulation. In embodiments, the device comprises a core segment, an annular flange to engage one surface of the atrial septum and two other annular flanges to engage another surface of the atrial septum.
