An apparatus for sealing a passage through tissue communicating with a blood vessel includes a bioabsorbable plug member coupled to the distal end of a carrier member. The plug member includes a lumen extending therethrough that communicates with a lumen extending through the carrier member. A sealing member is disposed in the plug member lumen for sealing the lumen. A guide member is slidable into the lumen such that edges of a groove extending between proximal and distal portions of the guide member engage a wall of the lumen to define a bleed back lumen. The guide member is inserted into the passage until the distal portion enters the vessel. The plug member is advanced over the guide member until the plug member enters the vessel, whereupon blood enters the bleed back lumen to identify the location of the vessel relative to the plug member.
