1. An apparatus for filling an opening in a wall of a body lumen comprising:
- a plug formed of a bioabsorbable material and defining an inner aperture extending through the plug from an upper surface to a lower surface thereof, the inner aperture having a plug engagement surface, the plug including a plurality of channels extending from an exterior surface of the plug, through a body of the plug, to the inner aperture;
a plurality of elongate members each extending slidably through a channel of the plurality of channels of the plug and selectively projecting into the inner aperture; and
an insert formed of a bioabsorbable material configured to be slidably received within the inner aperture, the insert having a first insert engagement surface configured to contact the plug engagement surface, the plug engagement surface having an undeformed inner diameter less than an undeformed outer diameter of the first insert engagement surface, and having a second insert engagement surface configured to contact the plurality of elongate members and urge the plurality of elongate members to extend outward and away from the plurality of channels of the plug and out of the inner aperture.

Abstract
An apparatus for occluding a venous or arterial puncture site is disclosed including a plug insertable within, or adjacent to, a puncture site in a wall of a body lumen. An insert is forced into an aperture within the plug to cause expansion thereof. The insert may be drawn into the aperture by applying tension to a line passing therethrough and secured to the insert. Barbs may secure to the plug to engage the wall of the body lumen or adjacent tissue tract. Elongate members passing through the wall of the plug may be forced outwardly into the wall of the body lumen or adjacent tissue as the insert is forced into the aperture.
