摘要

The present invention relates to an apparatus and method for positioning an apparatus and method for use in sealing the puncture site in a blood vessel, and then, properly positioned the sealing device. The positioning device, extends from the opening in the distal region of the device, but with a lumen that is located near the sealing device, the lumen extends to another opening in the proximal region of the device . when the distal opening is in communication with the blood in the blood vessels, blood flowing out of the proximal opening is shown to the user its location and flows through the lumen. The sealing device is withdrawn, so as to cut off blood flow to the distal port so that when this sealing device is located, the user knows the location of the sealing device.
