Abstract
The present invention provides for an apparatus to locate a blood vessel puncture having a bleed back entrance port near a first end, a bleed back exit port near a second end; and a lumen extending between the bleed back entrance port and the bleed back exit port, wherein said bleed back entrance port has a diameter substantially equal to or greater than the lumen diameter. The present invention further provides for a method for locating a blood vessel puncture by inserting a locator into a blood vessel lumen, the locator having a bleed back entrance port at a first end, a bleed back exit port at a second end, and a finger adjacent the bleed back entrance port, observing a blood flow out of the bleed back exit port, and withdrawing the locator out of the blood vessel lumen until the finger contacts the blood vessel wall.
