Claim:
1. A vascular closure system, comprising: a carrier tube; an expandable anchor mounted to the carrier tube and configured to extend through a vessel puncture to temporarily seal the vessel puncture from within a vessel; a first lumen positioned in the carrier tube and a second lumen positioned in the carrier tube, the first and second lumens having distal openings positioned distal to the expandable member; a bioadhesive material disposed outside of the vessel and configured to seal the vessel puncture; a sealing tip mounted to the carrier tube distal of the expandable anchor; a filament connected to and extending proximally from the sealing tip, wherein applying tension in the filament maintains connection of the sealing tip to the carrier tube, and releasing the tension in the filament permits release of the sealing tip and at least a portion of the filament within a channel formed in the bioadhesive material upon removal of the anchor through the bioadhesive material to seal the channel, the filament being movable through the expandable anchor, wherein the at least a portion of the filament is configured to extend outside of the bioadhesive material upon removal of the anchor.
