Abstract
An implantable device can be configured to occlude an opening in a septum of a heart, such as a perimembranous ventricular septal defect. The device can comprise an expandable member expandable from a first state to a second state upon contact with a fluid. The implantable device in the second state can be configured to occlude the opening in the septum, thereby preventing blood from leaking through the opening and across the septum. The implantable device can be substantially or completely devoid of metal, resulting in a reduced likelihood that the implantable device affects the function of heart valves near the opening of the septum or leads to tissue erosion.
