1. A system for treating a heart condition, the system comprising:
a sheath having a lumen and distal end sized and shaped to be positioned through an opening of an atrial septum of a patient;
a shunt comprising an anchor and a conduit, the anchor having a first region, a second region, and a neck region joining the first and second regions, the conduit affixed to the anchor to define a passageway through the shunt, the shunt configured to transition from a contracted delivery state within the lumen of the sheath to an expanded state, wherein the passageway maintains a continuous opening across the atrial septum in the expanded state and inhibits late lumen loss; and
a delivery catheter movably disposed within the lumen of the sheath and configured to advance the shunt through the lumen of the sheath until the first region protrudes from the distal end of the sheath and transitions from the contracted delivery state to the expanded state within a first atrium,
wherein the shunt and the sheath are configured to be retracted towards the atrial septum until the first region in the expanded state engages with the atrial septum within the first atrium, and
wherein the sheath is configured to be further retracted until the second region of the anchor is exposed from the distal end of the sheath and transitions from the contracted delivery state to the expanded state within a second atrium to implant the neck region at the atrial septum.
