1. A medical device comprising:
an elongate tubular body comprising a proximal portion, a distal portion, and a length therebetween, the elongate tubular body defining a lumen along the length;
wherein:
the elongate tubular body has an unexpanded configuration, and an expanded configuration in which the proximal portion of the elongate tubular body expands into a proximal retention member and the distal portion of the elongate tubular body expands into a distal retention member leaving a cylindrical saddle region extending therebetween; and
the elongate tubular body includes a constricted portion formed by a plurality of filament loops;
wherein:
each of the plurality of filament loops includes a membrane, covering, or coating on at least one of an inner or outer surface thereof;
each of the plurality of filament loops has a radially-inwardly directed distal free end; and
the distal free ends of the plurality of filament loops are movable between a first configuration overlapping one another to inhibit flow through the elongate tubular body, and a second configuration providing an open flow or access passage through the elongate tubular body.
 
7. A plug for selectively inhibiting flow through a tubular medical device, the plug comprising: a plurality of radially-inwardly directed overlapping filament loops circumferentially positioned with respect to one another and each including a membrane, covering, or coating on at least one of an inner surface or an outer surface thereof; wherein each of the plurality of filament loops has a radially-inwardly directed distal free end, and the distal free ends of the plurality of filament loops are configured to move between an overlapped closed configuration in which the plurality of filament loops are overlapped and contact one another to inhibit flow through the plug, and an open configuration allowing access through the plug.
 
12. A medical device, comprising: an elongate tubular body forming a lumen along a length thereof, the elongate tubular body having an unexpanded configuration and an expanded configuration; and a plug attached to or integrally formed with a portion of the elongate tubular body, wherein the plug is formed of radially-inwardly directed filament loops each including a membrane, covering, or coating on at least one of an inner or outer surface thereof, wherein each of the plurality of filament loops has a radially-inwardly directed distal free end, and the distal free ends of the filament loops are configured to move between a first configuration overlapping one another to limit flow through the lumen of the elongate tubular body, and a second configuration allowing access through the lumen of the elongate tubular body.
