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. In an aspect of the invention, the interatrial device comprises portions that are more flexible or less flexible than another portion of the device.
