Abstract
An apparatus for sealing a passage through tissue includes a bioabsorbable body disposed on a distal end of a handle device. The plug member includes a helical thread on its outer surface and the plug member and handle device include cooperating lumens communicating with a distal port. A sealing member is disposed within the plug member lumen. An obturator is inserted through the lumens until its distal tip extends beyond the plug member, the distal tip including a bleed back port. The plug member is threaded into a passage towards a blood vessel until the bleed back indicator identifies the location of the vessel with respect to the plug member. The plug member is released from the handle device, the handle device and obturator are withdrawn, and the sealing member seals the lumen. The plug member is left within the passage to seal the passage until the tissue heals.
