First Claim
1. A device for implanting into an atrial septum of a patient, the device comprising:
- a core region comprising a plurality of core segments surrounding a central opening, the core region being adapted and configured to be disposed in an opening in the atrial septum;
a distal retention region comprising a plurality of distal retention segments extending from the core segments, the distal retention segments being adapted to engage tissue on a left atrial side of the septal wall;
a proximal retention region comprising a plurality of proximal retention segments extending from the core segments, the proximal retention segments being adapted to engage tissue on a right atrial side of the septal wall; and
a retrieval region comprising a plurality of retrieval members each extending from an outward end of the proximal retention segments, each retrieval member comprising a connector at a proximal end, the connector being adapted to connect to a delivery system;
the device further comprising a first configuration and a second configuration, wherein in its first configuration, the distal retention region engaging the atrial septum in the left atrium, and the proximal retention region engaging the atrial septum in the right atrium, while the plurality of retrieval members extend in an elongated profile, and the connectors at the proximal end of each retrieval member are proximate to each other, and wherein in its second configuration, the distal retention region engaging the atrial septum in the left atrium, and the proximal retention region engaging the atrial septum in the right atrium, while the connectors at the proximal end of the retrieval members are disposed radially outward from the central opening of the core region.

Abstract
A device for implanting into an atrial septum of a patient. In some embodiments, the device has a core region to be disposed in an opening in the atrial septum; a distal retention region adapted to engage tissue on a left atrial side of the septal wall; a proximal retention region adapted to engage tissue on a right atrial side of the septal wall; and a retrieval region comprising a plurality of retrieval members, each retrieval member comprising a connector at a proximal end, the connector being adapted to connect to a delivery system. The device has a delivery configuration and a deployed configuration, the core region, distal retention region and proximal retention region each having a smaller diameter in the delivery configuration than in the deployed configuration, the retrieval member connectors being disposed proximal to and radially outward from the opening in the deployed configuration.

10. A method of implanting a pressure relief device in an atrial septum of a patient'"'"'s heart, the device comprising a retrieval portion, a proximal retention region, a distal retention region, and a core region with an opening, wherein the retrieval region has a plurality of retrieval members each extending from an outward end of the proximal retention segments and is proximal to the proximal retention region, the device comprising a first configuration and a second configuration, wherein in its first configuration, the distal retention region engaging the atrial septum in the left atrium, and the proximal retention region engaging the atrial septum in the right atrium, while the plurality of retrieval members extend in an elongated profile, and the connectors at the proximal end of each retrieval member are proximate to each other, and wherein in its second configuration, the distal retention region engaging the atrial septum in the left atrium, and the proximal retention region engaging the atrial septum in the right atrium, while the plurality of retrieval members of the retrieval region is disposed radially outward from the opening of the core region, the method comprising:
-
expanding the device into its first configuration, wherein the distal retention region, comprising a plurality of flexible retention segments, engages the septal wall in a left atrium of the patient'"'"'s heart, the proximal retention region, comprising a plurality of flexible retention segments, engages the septal wall in a right atrium of the patient'"'"'s heart, and the core region is positioned within an opening in the septal wall between the left atrium and the right atrium of the patient'"'"'s heart; releasing the retrieval members from the delivery system; and
thereby letting the device transition into its second configuration. - View Dependent Claims (11, 12)
