Abstract

Systems and methods for implanting a shunt for regulating blood pressure between a patient's left and right atria are provided. The shunt comprises an anchor having a neck region, first and second end regions, and a conduit affixed with the anchor formed of a biocompatible material that is resistant to transmural and translation tissue ingrowth and that reduces a risk of paradoxical embolism. The shunt may be advanced through the sheath until the first region protrudes from the sheath and self-expands within the left atrium. The shunt and the sheath may then be retracted until the first region contacts the left side of the atrial septum. The sheath may further be retracted until the counterforce exerted by shunt tension on the atrial septum overcomes the friction of the retained portions of the shunt such that the second region is exposed from the sheath and self-expands within the second atrium.
