First Claim
Patent Images
1. A device for implanting in an opening in a septal wall in a heart of a patient, comprising:
- i. a first annular flange comprising a plurality of flange segments, each of said flange segments of the first annular flange having a first end and a second end;
ii. a second annular flange comprising a plurality of flange segments, each of said flange segments of the second annular flange having a first and a second end, at least one of said flange segments of said second annular flange comprising a end adapted to be substantially parallel with and contact the septal wall when deployed; and
iii. a core segment having a first diameter when deployed, said core segment defining a passage adapted to permit fluid to flow therethrough from one side of said septal wall to another side of said septal wall,wherein the first ends of the first annular flange and the first ends of the second annular flange are contiguous with and define the core segment,wherein at least one of the flange segments of the second annular flange includes a first section that extends into the atrium and a second section that extends from the first section toward the septal wall,wherein the second end of the at least one of the flange segments of the second annular flange is adapted to be in contact with the septal wall,wherein at least a portion of at least one of said flange segments is more flexible than a portion of said core segment, andwherein 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 intra-cardiac pressure devices, placement catheters, methods of placement and methods of treating heart failure are presented. The intra-cardiac pressure devices presented allow sufficient flow from the left atrium to the right atrium to enable the relief of elevated left atrial pressure and resulting patient symptoms. The intra-cardiac pressure devices are made of a non-braided material.
