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 cylindrical core segment defining a passage;
a first annular flange adapted to engage a first surface of said atrial septum;
a second annular flange adapted to engage a second surface of said atrial septum,a flow control element comprising a tube within said passage and adapted to extend therethrough in an axial direction a distance beyond said annular flange into a septum of said heart.

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.
