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 The plug member is released from the handle device, the handle device and obturator are withdrawn, and the sealing member seals the lumen.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.

The apparatus of claim 17, wherein the plug member lumen provides fluid communication between the distal end of the plug member and the lumen of the elongated member. 19. The apparatus of claim 18, further comprising a second elongate member insertable through the plug member lumen such that a distal end of the second elongate member is disposed beyond the distal end of the plug member. 20. The apparatus of claim 19, wherein the distal end of the second elongate member comprises a location indicator for identifying when the distal end of the plug member is disposed adjacent a body lumen. 21. The apparatus of claim 20, wherein the second elongate member comprises a tubular member including a bleed back lumen, and wherein the location indicator comprises a bleed back port on the distal end of the tubular member, the bleed back port being in communication with the bleed back lumen. 22. The apparatus of claim 20, wherein the location identifier comprises an expandable member, the expandable member being expandable when the distal end of the second elongate member is disposed within a body lumen for providing tactile feedback of a location of the distal end of the plug member with respect to the body lumen. 23. The apparatus of claim 19, wherein the second elongate member comprises an obturator including a substantially atraumatic distal tip. 24. The apparatus of claim 19, further comprising a valve in the plug member lumen for substantially sealing the body member lumen yet accommodating insertion of the second elongate member therethrough. 25. The apparatus of claim 17, wherein the sealing member is biased towards a first configuration for substantially sealing the plug member lumen from fluid flow therethrough, and is movable to a second configuration for accommodating introduction of one or more devices through the plug member lumen. 26. The apparatus of claim 17, wherein the sealing member comprises a valve. 27. The apparatus of claim 17, wherein the plug member lumen includes a tapered portion reducing in cross-section, and wherein the sealing member comprises a generally annular-shaped member disposed adjacent a wide end of the tapered portion of the plug member lumen, the annular-shaped being movable into the tapered portion for substantially sealing the plug member lumen. 28. The apparatus of claim 27, further comprising a activation element coupled to the elongate member, the activation element extending into the plug member lumen for moving the sealing member into the tapered portion for substantially sealing the plug member lumen. 29.
