Abstract
A device (10) for treating heart failure in a patient. The device (10) comprising a body (12), at least one passage (18) through the body (12), at least one one way valve (20) in the passage (18) and a mounting means (14) adapted for mounting the body (12) in an opening provided in the patient'"'"'s atrial septum. In use, the device (10) is oriented such that, when the patient'"'"'s left atrial pressure exceeds the patient'"'"'s right atrial pressure by a predetermined amount, the one way valve(s) (20) opens to allow blood flow through the passage(s) from the left atrium to the right atrium to thereby reduce the left atrial pressure.

102. A method for treating a heart condition in a patient, the method comprising the steps of:
-
forming an opening in the patient'"'"'s atrial septum; inserting at least one valve in the opening such that the at least one valve allows blood flow through the passage from the left atrium to the right atrium when the patient'"'"'s left atrial pressure exceeds the patient'"'"'s right atrial pressure; and securing the at least one valve relative to the patient'"'"'s atrial septum, whereby, when the patient'"'"'s left atrial pressure exceeds the patient'"'"'s right atrial pressure, by a predetermined amount, the at least one valve opens to allow blood flow through the passage from the left atrium to the right atrium to thereby reduce the patient'"'"'s left atrial pressure and the valve prevents and the valve prevents flow when the right atrial pressure exceeds the left atrial pressure. - View Dependent Claims (103, 104, 105)
