In one example implementation, a device for closing an opening in tissue includes a proximal end and a distal end. The device further includes a port that extends from the proximal end of the device towards the distal end of the device. In addition to extending from the proximal end of the device towards the distal end of the device, the port includes a restriction zone and a storage region. The device further includes a blocking element that is configured to move between a neutral position, located in the storage region of the port, and a blocking position, located in the restriction zone of the port. When the blocking element is in the blocking position, the blocking element cooperates with the restriction zone in the port to assist in blocking fluid flow through the port.
